What is StreetTUNER?What is StreetTUNER?What is StreetTUNER?What is StreetTUNER?What is StreetTUNER?The StreetTUNER package is a software enhancement for the AccessPORT. Withit, you can custom design and tune your own AccessPORT map files for use onyour vehicle. In addition, the map files you create can be shared with otherStreetTUNER users.

The StreetTUNER software package does not replace the AccessPORT butinstead enhances its capabilities by allowing end-users the freedom ofcustomizing their ECU tuning.

With the StreetTUNER software package, you can interface directly with theECU to make live adjustments to the Realtime portion of engine mapping.When changes are necessary outside of the Realtime portion of enginemapping, you will save a Base map file and transfer it onto your AccessPORT.With the AccessPORT, you may then flash program your new data into yourengine computer (ECU).

Introduction to Real Time tuning technologyIntroduction to Real Time tuning technologyIntroduction to Real Time tuning technologyIntroduction to Real Time tuning technologyIntroduction to Real Time tuning technology

Designed and pioneered by AccessECU, the patent-pending Real Time tuningtechnology allows you to instantly adjust ECU parameters that dictate how yourengine performs. The factory ECU still controls and runs all of its sensors andauxiliary components. All the factory fail-safes are also fully retained for anengine management system virtually unparalleled by any aftermarket system.

While there are other systems that allow manipulating the data in the factoryECU to alter engine performance, none allow the tuner the ability to test theirchanges in real-time while the engine is running. With other systems, tunersmust modify the ECU program file on their PC, turn the engine off, set the ECUinto a special mode, send the new data to the ECU, and then restart the car totest if those changes were effective or not. Due to these cumbersome and timeconsuming tasks, it is very difficult for even highly skilled tuners to truly extractthe best from the car in a reasonable time frame.

Furthermore, there is a hardware limitation in modern ECUs that limits the totalnumber of times the data may be written. The original ECU manufacturer onlyguarantees a minimum of 100 successful reprograms. When using the RealTime tuning technology, this limitation is not a factor for tuning as making RealTime changes does not reduce the life-span of the ECU.

With the AccessECU Real Time tuning technology, you can now modify andverify all major tuning parameters instantly to produce a higher quality tune ina fraction of the time.

Understanding Map TUnderstanding Map TUnderstanding Map TUnderstanding Map TUnderstanding Map Typesypesypesypesypes

Base MapsBase MapsBase MapsBase MapsBase MapsThe Base map files represent the entire ECU ROM image, or software, that iscontained on the ECU. This includes everything from program data to the tabledata you will be able to modify with this software. This is, in concept, the exactsame as other ROM editing software programs available for tuning ECUs.

Base maps are activated by flashing their contents on the ECU. This is again thesame, in concept, to other ECU tuning packages. So in the traditional vein ofECU tuning, this is the same as its always been.

Thus, there are no limitations to what can be changed in a Base map so far asthe base map is concerned. The only limitation is with the software and whatdata you have access to change.

Realtime MapsRealtime MapsRealtime MapsRealtime MapsRealtime MapsThis unique map type, developed by AccessECU, allows certain data to bechanged while the engine is running and without requiring the data be flashedinto the ECU. This is a unique concept and technology, available only throughAccessECU. The data stored in these maps are not simple values that applyblanket corrections to ECU maps. They are the actual data, at the same resolu-tion shown to you in the StreetTUNER software.

By empowering your ECU with this unique technology, you are able to makeadjustments to your tuning tables and test their result before ever committing toa final value. This is the same convenience provided by many aftermarketengine management systems, but something unheard-of with the factory ECU.

There are some limitations to Realtime maps with regard to how much data canbe changed at a time. For instance, its not possible to change some programspecific data like Check Engine Lights on the fly. The limitations are normallyreserved for tuning functions that require very little or no Realtime testing.When it is not possible, it is clearly documented for you in these instructions.

For example, during the course of fine-tuning an aftermarket intakesystem the ECU may have learned A/F Correction values that are no longernecessary. While the ECU will eventually learn new corrections, you may speedits process along by resetting the ECU with the StreetTUNER.

Notes on Data ManipulationNotes on Data ManipulationNotes on Data ManipulationNotes on Data ManipulationNotes on Data ManipulationIn an effort to improve the effectiveness of manipulating data when using theIncrease Value [ + ] or Decrease Value [ - ] options, some parameters arechanged at a rate greater than the maximum allowed resolution by the ECU. Ifwhile manipulating data you find the need to achieve a more exact value, youmay use the Direct Value Edit [ E ] feature to input your exact data.

After inputting the exact value you desire in a table, occasionally the displayedvalue varies slightly from your original input. This occurs in the event that theECU is not capable of the exact value you inputted, and the software isdisplaying the closest possible value the ECU can use. This is due to the factthat resolutions when altering table values vary depending on the table. Somedata tables in the ECU have higher resolution than others. This is a function ofthe ECU, not a limitation of the StreetTUNER software.

NOTE:NOTE:NOTE:NOTE:NOTE: The Ignition key must be in the ON position (engine running or off)before you can enable Live Tuning.

To enable Live Tuning, select ECU -> Live TECU -> Live TECU -> Live TECU -> Live TECU -> Live Tuninguninguninguninguning or use the [ CTRL + L ] hotkey.A checkmark will appear next to the menu option when Live Tuning is activated.The status bar at the bottom will also indicate when you are connected to theECU.

If any errors occur while attempting to connect to the ECU, verify the Ignition isin the ON position and that you are properly connected to the vehicle using theDiagPORT cable. Also verify you have selected a COM port in the ConfigureOption setting. If you do not know what COM port to use, select Auto-DetectAFTER you have connected the DiagPORT cable to the vehicle. Turn to page 62for additional troubleshooting notes if problems persist.

When first connecting to the ECU, the StreetTUNER will download all of theRealtime Map data from the ECU. This data then becomes what is viewed andmanipulated with the StreetTUNER. It is important to note however that noBase Map data is downloaded at this time.

If you open a Map file while in Live Tuning mode, it will upload the Real Timemap data to the ECU for its immediate use.

While in Live Tuning mode, changes you make to the tables signified as Realtimetables occur instantly on the ECU.

Take great care while manipulating data with Live Tuning enabled. The changesyou make become active on the ECU immediately. Incorrect or unsafe changesmay result in engine damage.

Once you have completed the necessary tuning, it is advised to deactivate LiveTuning when not actively tuning or logging the ECU.

It is considered good practice to deactivate Live Tuning before exiting theprogram.

Live tuning the factory ECU is an unique technology developed exclusively byAccessECU. The factory ECU was never designed to allow for this type ofinteraction.

Due to this unique feature, users of the StreetTUNER software can address theirvehicle’s tuning needs in a manner slightly different than those using othertuning solutions.

When tuning Realtime adjustable parameters, there is no need to periodicallyflash them into the ECU as a base map in order to make them “stick”.

The recommended method for tuning is as follows:

1. Make any necessary off-line changes to settings that are noted as BaseMap Tables. These items can be Closed Loop parameters, Boost Limits,and/or Knock Correction values. Save those changes as a Base Map,transfer them to your AccessPORT and flash this data to your ECU usingthe AccessPORT.

2. Connect to the ECU using StreetTUNER’s Live Tuning mode. When firstconnecting, the Realtime data on the ECU will be downloaded intoStreetTUNER and displayed in the table windows. NO BASE MAP DATAIS DOWNLOADED ON CONNECTION WITH LIVE TUNING.

3. If you wish to use a previously saved a Realtime or Base Map file thatholds data different from what you currently have on the ECU, you canFile -> Open that map at this time and all the Realtime data in thatopened map will be transferred to the Realtime section of the ECU forimmediate use. It will overwrite the existing Realtime map data. BASEMAP DATA WILL NOT BE EFFECTED.

If you do not have any previously saved maps you wish to use, skip thisstep.

4. Begin tuning the Realtime parameters. You may continue to fine tunethe Realtime data settings over a period of several days, weeks ormonths and they will be retained by the ECU. Only in the event thatpower is completely lost to the ECU by means of the ECU beingphysically removed from the vehicle or the battery being removed forsome period of time will Realtime data be lost. Turning the car off doesnot erase or otherwise corrupt the Realtime data.

5. Once you are satisfied with the new tune, you may then save it as aBase Map and flash it to your ECU. The flashed data will not beembedded on the ECU and cannot be erased by any means other thanflashing different data to the ECU. 25

In order to enable Live Tracing, you must first have connected to the ECU bymeans of activating the Live Tuning mode.

Live tracing will display what part of the currently viewed table is beingaccessed by the ECU. This is particularly useful when tuning the car on a load-based dyno where you need to verify the portion of the table being edited isthe same portion the ECU is currently using. It can also be very useful for roadtuning when trying to smooth out a driveability issue or stumble in thepowerband.

Once enabled, the accessed cell for the table you are currently viewing will behighlighted with a light blue background color. As the accessed cell changes, atrace will be shown to help visualize both what is currently being accessed aswell as what had been accessed previously.

The X and Y axis values will also be highlighted to help visually follow theaccessed location.

A checkmark will appear next to the menu optionwhen Cursor Tracing is activated. The status bar at the bottom will also indicatewhen Cursor Tracing is active.

In order to enable Cursor Tracing, you must first have Live Tracing mode acti-vated.

Cursor tracing enhances the Live Tracing function by forcing the editing cursor tofollow the currently accessed cell. This is useful for editing the cell(s) the ECU iscurrently accessing without trying to manually follow the live tracing cursor.

An example of this feature’s use would be fine tuning ignition timing whileholding the engine under load with a load-based dyno. The tuner can focus onthe real-time power reading of their dyno while using the + / - keys in thesoftware to find the optimal timing value.

Another example would be wastegate duty cycle adjustments while performingroad tuning. With cursor tracing changes could be made while they are experi-ences on the road without the tuning being distracted by trying to find thecurrently accessed value on the screen.

Before Datalogging for the first time, it is recommended to perform the follow-ing steps: (if you have already performed these steps, go to page 28)

1. Start by having the software in Offline mode. If you have alreadyconnected to the ECU, disconnnect at this time before continuing.

2. Go to the Configure Options window (Edit -> Configure OptionsEdit -> Configure OptionsEdit -> Configure OptionsEdit -> Configure OptionsEdit -> Configure Options) andclick on the Logging tab.

3. The Log Rate slider is defaulted to 10 samples per second. Dependingon how much data you plan on logging at the same time, this may betoo high and result in repeated data in the log files. If this occurs, goback into this window and reduce the Log Rate. A typical Log Rate for7-10 logged parameters is 7. If you log more parameters, you likelywill need to REDUCE your log rate. If you log fewer parameters, youmay be able to use a higher log rate.

4. Configure the Log File Folder. This is the folder where log files willautomatically be saved to. The default folder is the StreetTUNERinstalled folder. (default: c:\Program Files\AccessECU\StreetTUNER )

5. Click OK to close window once all settings have been made.

Next, you will need to connect to the ECU by being in Live Tuning mode(ECU -> Live TECU -> Live TECU -> Live TECU -> Live TECU -> Live Tuninguninguninguninguning).

MAP ManagementMAP ManagementMAP ManagementMAP ManagementMAP Management

File ManagementFile ManagementFile ManagementFile ManagementFile ManagementThere are two primary types of files to become familiar with when using theStreetTUNER software: Base Map files and Realtime Map files. Each offers itsown unique capabilities and uses. Getting the most of our the StreetTUNER willrequire having a good understand how the potential of each of these file times,as well as their limitations.

Base Map FilesThese files represent complete map files with virtually no limitations.Any and all data you adjust can be saved in the base map format. Thebest way to think of these files are as complete ECU programs. Theycontain not only all the Base Map data, but also everything normallyincluded in the Realtime Map files.

To use Base Maps, you must flash the map onto the ECU using the[CHANGE BASE MAP] option on your AccessPORT.

StreetTUNER specific Base maps are identified with their unique fileextension: .stb

Realtime Map FilesThe Realtime map files represent a new technology pioneered byAccessECU. The unique feature of Realtime Map files is that they can beloaded while the engine is running.

Realtime map files contain the table data that is marked with a red “R”.This means the complete fuel, timing, boost, and other maps are storedin the Realtime map files. This data can then be sent to the use, for itsimmediate use, when using the [SWITCH MAP] function of the Access-PORT.

StreetTUNER specific Realtime map files are identified with their uniquefile extension: .str

35

Loading Map FilesLoading Map FilesLoading Map FilesLoading Map FilesLoading Map FilesA Base or Realtime map can be loaded into StreetTUNER for either offlineediting, or to be applied to the ECU’s Realtime section if already in Live Tuningmode. Even if you open a Base map file, the Realtime data stored in that file willbe sent and activated on the ECU.

If you want to design and save a new Base Map file, it is advised that you firstload a Base Map file you wish to start from. This is because some base map filescontain special data not present in the stock base map. An example of thiswould be the Speed Limiter that is present in the Stock base map but may beremoved in other provided Base maps.

If you open a Map file and THEN connect to the ECU in Live Tuning mode, all theRealtime data loaded on the ECU will be downloaded and overwrite any previ-ously loaded map data.

Saving FilesSaving FilesSaving FilesSaving FilesSaving FilesYou can save your work in either the Base map or Realtime map format. Whensaving a Realtime map, all the table data designated as a Realtime tunable valuewill be saved.

If you save a Base Map, all the map data designated as a Realtime tunable valueand any StreetTUNER adjustable base value will be applied to the Working BaseMap file you have loaded. This is either the last Base Map file you’ve opened,designated as the “Working File”, or the stock base map if no others had beenopened.

When saving a map, you will be presented with the following dialog box.

Sharing Map FilesSharing Map FilesSharing Map FilesSharing Map FilesSharing Map FilesThe StreetTUNER has been designed specifically to allow fellow enthusiasts toshare their work for the benefits of others, as possibly themselves.

All maps generated are compatible with other StreetTUNERs using the same typeof AccessPORT. File data can be compared, edited, and loaded on your ECU orAccessPORT.

When sharing StreetTUNER maps, it is helpful to include a brief description ofyour work in the properties section of the Map File. This may be accessed whenusing the integrated Map Management software built into the StreetTUNER.

Map ManagerMap ManagerMap ManagerMap ManagerMap ManagerThe ability to manage the maps on your AccessPORT is integrated into theStreetTUNER software. The stand-alone version of the Map Manager softwarewill not be able to load or read StreetTUNER format files. For this reason, youcan only manage the maps on your AccessPORT by using the Map Manager builtinto the StreetTUNER software.

All other functionality of the Map Manager is the same as before. It has beendesigned specifically for StreetTUNER applications. It can load and manageStreetTUNER format map files, but will not be able to open or manage standard,non-StreetTUNER format map files.

In addition, the standard Map Management software normally provided as itsown application will no longer be able to communicate to your AccessPORTonce it has been upgraded to use the StreetTUNER software.

TTTTTunable Punable Punable Punable Punable ParametersarametersarametersarametersarametersThe following is a list of tunable parameters and a brief description regardingtheir function.

FFFFFuel Tuel Tuel Tuel Tuel Tablesablesablesablesables

FFFFFuel Injector Latencyuel Injector Latencyuel Injector Latencyuel Injector Latencyuel Injector LatencyAll fuel injectors require a certain amount of time to open fully andbegin flowing their rated amount of fuel. This time to open is referredto Injector Latency. This condition may also be referred to as InjectorDead Time. The amount of latency an injector has can be dependanton several factors such as Battery Voltage and Fuel Pressure. Lowerbattery voltage will increase the injector’s latency (dead time).Likewise, higher Fuel Pressure may also increase the injector’s latency.

The factory ECU has an Injector Latency adjustments table based onBattery Voltage. The data in this table is represented in milliseconds.This is the only table that exists for the sole purpose of adjustinginjector latency values.

This table is a BASE Map parameter only and cannot be tuned inRealtime. No changes will take effect until you flash the Base maponto your ECU with the AccessPORT

Tuning TipsYou will tune this map if you’ve changed injectors and/or fuel pressure.If using stock, STI (pink) or modified factory injectors, these values donot need to be altered. For other brand injectors, try and contact themanufacturer for the latency (dead time) values. Most will be able toprovide you with this data and the Voltage and Fuel Pressure they arereferenced at. Use that as a starting point and modify from there.Don’t be afraid if your final values differ from what the manufacturerprovided.To tune this table, it is suggested that you first establish a good InjectorScale value through a best guess estimate. Adjust the latency valueswith the car at idle. If the car is running lean (positive fuel trimcorrection values) you should try increasing the latency value. Doing sowill extend your total injector on-time. If the car is running rich(negative fuel trim correction values), try decreasing your latencyvalues. In most cases, aftermarket injectors are Slower than the factoryinjectors and thus need Higher fuel latency values.

40

FFFFFuel Injector Scaleuel Injector Scaleuel Injector Scaleuel Injector Scaleuel Injector ScaleThis singular value is used to represent the fuel injector size or flowrate. Any changes to this value will effect ALL maps within the ECUrelated to fuel delivery during both closed and open loop operation.When using stock injectors, this value DOES NOT need to be altered.

When adjusting this value, a lower number represents an LARGERinjector whereas a larger scale value will represent a SMALLER injector.The value displayed is not converted into an injector cc size due to itsinability to be translated accurately. Please see the Tuning Tips belowthe tips on determining a injector scale value.

This value can be adjusted in Realtime. The value can be changed witha Realtime or Base Map stored on the AccessPORT.

Tuning TipsDo not adjust this value when using a stock injector. To calculate astarting value for a different injector size, use the following formula:

New Scale Value = (Original Injector Size / New Injector Size) * OriginalScale Value

For example, lets say you are replacing your factory WRX injectors(420cc) for aftermarket 650cc injectors. The formula would look like:New Scale Value = (420cc / 650cc) * 6442, so;New Scale Value = 4162

Tip: For STi (Pink) injectors start with a value of 5120.Tip: For STi (Pink) injectors start with a value of 5120.Tip: For STi (Pink) injectors start with a value of 5120.Tip: For STi (Pink) injectors start with a value of 5120.Tip: For STi (Pink) injectors start with a value of 5120.

Input this value as a starting point. You will likely need to tune fromthere. To fine tune the scale value, display the A/F Learning and A/FCorrection values with the Dashboard. With the engine idling, makeadjustments to the scale value until ( A/F Correction + A/F Learning ) =+/- 5%. The closer you can get to 0% is ideal, but do not begin tuningany other fuel maps until you at least have it within the +/- 5%window of total correction.

In addition, do not attempt to tune for an aftermarket Intake andaftermarket injectors at the same time. An aftermarket intake willeffect your A/F Correction and Learning values at idle, making it nearlyimpossible to find an accurate Injector Scale Value. It is advised you dothe injector scale tuning using a stock intake if possible. If you plan touse an aftermarket intake, it can be installed and the necessary tuningperformed AFTER (or BEFORE) you have found the optimal Fuel InjectorScale value but not attempt both at the same time.

Primary FPrimary FPrimary FPrimary FPrimary FuelueluelueluelThe primary fuel table used when the system has NOT beenexperiencing a high level of detonation. Table data is represented intheoretical Air/Fuel mixture values. In most cases this is relativelyaccurate. However, do not tune under the assumption that it willmake corrections based on this value in an effort to achieve it. TheECU does not use a closed loop system to meet these values.A higher value represents leaner the air/fuel ratio, the lower value thericher the air/fuel ratio.

Table is referenced by RPM versus Calculated Load. Calculated load isdetermined by the mass of air (gram/sec) per cylinder.

Table data, RPM axis and Load Axis can all be tuned and adjusted inRealtime. All data can be changed when using either Realtime or Basemap files from your AccessPORT.

Tuning TipsThe leanest value allowed by the ECU in the map is 14.7:1. Variablessuch as octane rating, spark plug temperature & gap, intake airtemperature, and application (street driving, road racing, rally racing,drag racing, etc.) must be taken into account when tuning this fueltable.

There are many philosophies with regard to optimal A/F ratio. Somewill tune according to Load and engine RPM where the A/F Ratio willgradually run richer to protect the motor as engine RPMs increase(factory OEM style). Other methods include tuning the A/F Ratioaccording to boost, where you target your “ideal” A/F ratio at theonset of target boost, regardless of engine Load or engine RPM. Workwith whatever method provides you the best results.

42

It is highly advised to tune this table while using Live Tracing and/ordatalogging the RPM and Calc Load values to help determine where inthe map the ECU is accessing for fuel targets. In the event you loghigher Calc Load values than displayed in the table, you will need torescale the Calc Load reference values (Hortizontal Y Axis).

When tuning this table, keep in mind the A/F Learned correction (LongTerm Fuel Trim) will effect the actual A/F Ratio. For example, if you havea -10% A/F Learned correction value, your total A/F Ratio will be leaner(less fuel) than the value you have in the table.

Intake CalibrationIntake CalibrationIntake CalibrationIntake CalibrationIntake CalibrationThe calibration table for the Mass Air Flow (Intake) sensor. Thecalibration table is referenced by the Voltage generated by the Mass AirFlow sensor, with the table values representing the grams a second ofair that is passing across the sensor. The Mass Air Flow sensor worksacross a 0-5 Volt range.

MAF Voltage values and g/sec air flow values can both be adjusted inRealtime. All data can be changed when using either Realtime or Basemap files from your AccessPORT.

Tuning TipsThis calibration may need to be altered when using an AftermarketIntake system. The air flow values are determined when measured inthe stock MAF housing. If you increase (or decrease) the size of thehousing (piping) the MAF sensor resides, this will effect how much airis passed across the housing for a given MAF voltage. If you increasethe diameter of the housing, more air will pass through for the samegiven voltage compared to stock. Thus, you need to increase orotherwise modify the Air Flow values for each given MAF voltage.Failure to do so will result in inaccurate A/F targets at both closed loopand Wide Open Throttle.

To tune, enable Live Tuning and Live Tracing while monitoring A/FCorrection and A/F Learned values. Let the engine idle and adjust theactive cells until your A/F Correction and Learning values are close to0%. Drive the car in closed loop (light throttle) and continue to modifythe active cells, all the while targeting a 0% correction value. In orderto tune the other cells at high load, determine how much change wasrequired at idle and low load and apply your best guess to the untunedcells.

Continue adjustments until the car has a stable and expected A/F Ratiothat matches your Low/High Detonation Fuel tables. Patience is a keyto producing a good MAF calibration table. Keep in mind not allintakes act the same. Some will have turbulance or poor flow issues atcertain MAF voltages which will require additional tuning.

Tip-In EnrichmentTip-In EnrichmentTip-In EnrichmentTip-In EnrichmentTip-In EnrichmentEffects the amount of enrichment used during throttle “tip in”conditions. This is the situation when the throttle is opened quickly, anextra burst of fuel must be injected to improve throttle response. Tablevalues are arbritrary values referenced against a delta (change) inthrottle position. The higher the values, the more fuel will be injected.

This map is a BASE Map parameter only and cannot be tuned inRealtime. No changes will take effect until you flash the Base map ontoyour ECU with the AccessPORT

Tuning TipsThese values should only need adjusting when using fuel injectors thatflow more (or less) than the factory injectors (420cc), and/or whenusing more (or less) than factory fuel pressure (43.5psi @ 0 psi). As theinjector size increases, the amount of Tip-In enrichment requiredtypically decreases. The goal in tuning these values will be to provide aclean throttle response when the throttle is suddenly opened from acruise condition. In addition, you should watch your A/F Ratios toverify the A/F ratio does not suddenly increase/descrease from expectedvalues when quickly opening the throttle. Go with what “feels” bestand what matches the intended driving style and application of thevehicle and driver.

Dynamic Ignition AdvanceDynamic Ignition AdvanceDynamic Ignition AdvanceDynamic Ignition AdvanceDynamic Ignition AdvanceThis is a dynamic ignition advancing table which uses engine RPM forthe y-axis and calculated load for the x-axis. This map is an auto-tuningclosed-loop ignition advance map that determines the authority theECU has to advance ignition timing in addition to the primary ignitionadvance table values.

To determine the final Dynamic Ignition Advance, the ECU will take thevalue looked up in this table (for the current RPM and Calc Load) andmultiply it against the current Ignition Advance Multiplier (percentage).

In the event Knock is detected, the ECU will reduce the IgnitionAdvance Multiplier (percentage) so less of the Dynamic IgnitionAdvance table is added on top of your Primary Ignition Advance table.

All values are in degrees BTDC (before top dead center).

This table is a BASE Map parameter only and cannot be tuned inRealtime. No changes will take effect until you flash the Base maponto your ECU with the AccessPORT.

Tuning TipsUse this table to give the ECU the ability to add timing on top of yourPrimary Ignition Advance table. This provides the ECU with the abilityto dynamically use the optimal Ignition Advance value for every givencondition.

Keep in mind that if conditions are optimal, the ECU will add the fullamount in your Dynamic Ignition Advance to your Primary IgnitionAdvance table. Take care not use too much total Ignition Advance thatthe engine will Knock when conditions are optimal.

48

Primary IgnitionPrimary IgnitionPrimary IgnitionPrimary IgnitionPrimary IgnitionThis is the primary ignition table which uses engine RPM for the vertical(Y)axis and calculated load for the hortizontal (X) axis. All, if any,corrections made to ignition timing will be based on the values lookedup originally in this table. These values are in degrees BTDC (before topdead center); the higher value the more ignition advance, the lowervalue, the lower the ignition advance.

Table data, RPM axis and Load Axis can all be tuned and adjusted inRealtime. All data can be changed when using either Realtime or Basemap files from your AccessPORT.

Tuning TipsVariables such as octane rating, spark plug temperature & gap, intakeair temperature, and application (street driving, road racing, rallyracing, drag racing, etc.) must be taken into account when tuning thistiming map. When tuning Ignition Advance, keep in mind that yourfinal actual ignition advance value will also include all, or some portionof, the Dynamic Ignition Advance map, as well as any corrections.

If your boost and fuel mapping is ideal for your configuration, you candatalog your Ignition Advance, Dynamic Ignition Advance and IAMvalues to determine if you are using too much (or too little) timingaccordingly.

There are two popular schools of thought with regards to IgnitionAdvance tuning, one which utilizes the Dynamic Ignition Advance tableto add in a majority of the ignition timing and the other philosophy ofreducing the dynamics of the Dynamic Ignition Advance table byreducing its values and adding them instead into the Primary IgnitionAdvance table. Use whichever philosophy best meets your goals andcomfort level.

It is advised you make small adjustments when tuning your PrimaryIgnition Advance table. Keep in mind you will need less IgnitionAdvance as the engine’s Volumetric Effeciency increases. This meansyou will typically use less ignition advance near or at peak torque.After your torque peak, you typically will want an increasing ignitionadvance. Best power typically is found near the threshold of knock, souse care when tuning. However, it is also possible to make less powerwith more ignition advance without actually reaching the knockthreshold. This is where tuning on a load-based dyno with realtimefeedback can be very beneficial.

Boost LimitsBoost LimitsBoost LimitsBoost LimitsBoost LimitsDefines the limits for Boost Pressure. Once this value has beenexceeded, the ECU will cut fuel to the engine until boost drops belowthe limit. Table is referenced by Barometric Pressure, which is meant toallow for variable limit values based on air density, atmosphericconditions and altitude. As the air pressure decreases, theturbocharger RPM must increase for the same boost pressure. Doingso may result in turbocharger and/or engine damage, thus the ability toset a lower limit at lower barometric pressures. Boost Limit values arerepresented in boost pressures (above 1 atm, not taking into accountcurrent barometric pressure)

Boost TBoost TBoost TBoost TBoost TargetsargetsargetsargetsargetsThis table represents the boost you desire according to engine RPM andthrottle position. These values can be set to imperial or metric values inthe Configure Options selection from the Edit -> Configure Optionsdrop down menu. The higher the value, the higher the target turboboost pressure target, the lower the value the lower the target turboboost pressure target.

Table data, RPM axis and TPS Axis can all be tuned and adjusted inRealtime. All data can be changed when using either Realtime or Basemap files.

Tuning TipsIt is recommended that you establish a good Boost Target settingbefore tuning any other Boost Control tables. We suggest you staywithin the efficiency range of the turbo compressor map and you donot overspin the turbo. When the turbo is run beyond its efficiencyrange it basically turns into a flame thrower increasing intake airtemperatures beyond an acceptable range. If the vehicle has stockcams, heads, turbo, or intercooler, we highly suggest you taper downthe boost level starting at 5,400 RPMs to promote turbo and enginelongevity.

If the vehicle does not produce an appreciable horsepower and torquegain per every pound of manifold pressure that is added, then do notcontinue to run higher boost levels. Excessive boost levels can createcombustion circumstances that will damage or destroy a motorassembly.

Caution: the closed-loop boost control system is very responsive. Whileyou are tuning, the ECU is going to do everything within its authorityto hit these boost targets so long as your other tables are tunedproperly to allow the ECU to do so.

TTTTTurbo Dynamics - Bursturbo Dynamics - Bursturbo Dynamics - Bursturbo Dynamics - Bursturbo Dynamics - BurstRelated to the wastegate duty cycle values. The ECU will take thecurrent Target Boost Map value and reference it against the actualboost pressure. Based on the amount of “error” between the boostyou want and the boost you are getting, the ecu will use the TurboDynamics maps to make corrections.

The Burst table is for larger errors, typically seen when first applying fullthrottle (ie: spool up). The table values represent percentagecorrections made against the wastegate duty cycle value. They arereferenced by the actual amount of error. Use this map to improveinitial “spool” of the turbocharger. This is tuned to correct boostspiking or slow boost response.

Boost Correction and Correction Percentage can all be tuned andadjusted in Realtime. All data can be changed when using eitherRealtime or Base map files from your AccessPORT.

Tuning TipsIf during the course of boost tuning you find the turbocharger reachesor overshoots target boost and then falls and climbs rapidly, tryadjusting the far left and far right values to be closer to 0%. Forexample, if the far left and far right values are -9% and 9% respectively,you may try reducing those to -4% and 4% to stablize boost pressures.

The ECU will use this tableto fine-tune the wastegate duty cycle to maintain the desired targetboost. The table values represent percentage corrections made againstthe wastegate duty cycle value. They are referenced by the actualamount of error. Use this map to improve stability in your boost onceyou’ve achieved target boost pressure. This is tuned to correct boost“hunting”.

Boost Correction and Correction Percentage can all be tuned andadjusted in Realtime. All data can be changed when using eitherRealtime or Base map files from your AccessPORT.

Tuning TipsIf during the course of boost tuning you find the turbocharger spoolsup to target boost pressure but then starts to oscillate by ~1psi aboveand below target boost in a rapid but consistent pattern, you may tryadjusting the values to be closer to 0%.

WWWWWastegate Duty Cycle -astegate Duty Cycle -astegate Duty Cycle -astegate Duty Cycle -astegate Duty Cycle -This table is used to help achieve the boost levels set in the TargetBoost Map by driving the OEM electronic boost control solenoid.

These values are in % of duty cycle for the boost control solenoid. Thisboost control solenoid is a “bleeder” device used to achieve higherthan wastegate actuator boost levels. By running a duty cycle on theboost control “bleeder” solenoid, you effectively decrease the boostpressure seen by the wastegate actuator. This in turn keeps thewastegate closed longer which increases the amount of boost pressuregenerated by the turbocharger.

Table data, RPM axis and TPS Axis can all be tuned and adjusted inRealtime. All data can be changed when using either Realtime or Basemap files.

Tuning TipsIt is recommended that you establish a good Boost tune beforemapping any other maps. We suggest you start with low duty cyclevalues, then datalog RPM, relative boost pressure, and wastegate dutycycle to see what duty cycle the ECU is trying to run in order to achievethe boost pressure specified in the Boost Target Map. If the wastegateduty cycle values are too low, you will not achieve your target boostpressure. If the wastegate duty cycle values are too high, you willovershoot your boost targets and potentially damage the engine.Gradually increase the Wastegate Duty cycle values in this table,according to what you see in your data logs, until you achieve yourtarget boost pressure.

We do not suggest you run a wastegate duty cycle of more than 95%to prevent overheating or lock-up of the wastegate solenoid, and topromote the longevity of the wastegate solenoid.

Idle SpeedsIdle SpeedsIdle SpeedsIdle SpeedsIdle SpeedsThe base idle speeds used depending on if A/C is on or off. This is thefinal idle speed used after the engine has warmed to normal operatingtemperature.

The left hand value is Idle Speed with the A/C Off.The right hand value is Idle Speed with the A/C On.

Dynamic Advance MultiplierDynamic Advance MultiplierDynamic Advance MultiplierDynamic Advance MultiplierDynamic Advance MultiplierThe primary use of this value is for the Dynamic Ignition Advance table,and it represents the tendency for the engine to knock (detonate) for itsgiven mapping and conditions. The higher the value, the “healthier”the state of tune. As the engine experiences detonation, this value willbe decreased. In addition, if this value goes below 4 , the ECU willdefault into a safer fuel map.

Valid values are 1 to 16. Resolution is 1. This means the ECU normallylooks for conditions based on 1 increments. Default value is 8. You canedit this to start at any value you desire, but this action does not LOCKthe value. The ECU will still learn based on conditions.

This value is used for the Dynamic Ignition Advance table. To determinehow much Dynamic Ignition Advance to use, this value is divided by 16.The result is then multiplied against the Dynamic Ignition Advance tablevalue and added to the Primary Ignition Advance table.

Example: if DAM = 12:12 / 16 = 0.75 (75%)( Dynamic Ignition Advance table value * 0.75 ) + Primary Ign. Adv.

The Advanced Parameters window allows you to deactivate/activate the Enginecomputer’s DTC Diagnostic Trouble Codes, a.k.a. CEL codes. Changes onlyeffective when saving Base Map files. Changes do not become active until BaseMap is flashed to ECU using the AccessPORT.

These values represent possible emissions or low-priority DTCs that can occurwith the stock vehicle. When modifying parts of the vehicle, such as exhaust, itmay be necessary to deactivate particular codes.

While it is not necessarily recommended to simply disable all codes, doing sodoes not effect any other operation within the ECU. The change made simplylets the ECU know if it should warn the owner in the event it detects a problem.The program code designed to detect the problem is not altered, only if itshould be reported.

The end result will be that the Check Engine Light will not illuminate for aparticular problem if you’ve deactivated the associated code(s). Keep in mindthat each sensor typically has several codes associated to it.

If the box to the left of the DTC Code is checked, the code is ACTIVE and maybe set causing a CEL light to appear.

If the box to the left of the DTC Code is NOT checked, the code is INACTIVE andwill not cause a CEL light to appear even in the event the condition for thattrouble code has been met or otherwise set.

Reference your AccessPORT manual or a Subaru service manual for a moredetailed explanation of the codes meaning.

Baud rate: This configures the COM port's speed when communicating. Cur-rently, the value should stay at "4800."

Data rate: This configures how long StreetTUNER will wait to see a responsefrom the ECU during communications.

02/03/04/05 WRX: Recommended data rate is 100ms.

04/05 STi | 04/05 Forester XT (MT/AT) | 05 Legacy GT (MT/AT): Recom-mended data rate is 150ms.

If communications seem unstable or if StreetTUNER disconnects from the ECUwhen data logging, try upping the data rate slightly.

Retries: This configures how many times StreetTUNER will retry communication ifthe time configured in Data Rate elapses.

Normally you will not want to change this value from the default unless thereare severe communication issues.
