An updated release of AEMPro and a new ECU Firmware release is out!AEMPro v3.22 AEMLog v3.10Strategy v1.19b

Changes from v1.11 to v1.19:

Firmware:1. Improved automatic transmission torque converter lockup function2. Added an integrated radiator fan / air conditioning control feature3. Improved O2 FB function4. Improved Alt control function5. Improved the engine load calculation function for use with frequency inputs6. Added selectable analog inputs for MAP, MAF and TPS inputs (previously restricted to

individual input pins)7. Added programmable telemetry function8. Added accel fuel warmup enrichment table

AEM Pro:1. Expanded configure outputs dialog for AEM by adding a third section titled Switched Output

Configure.2. Added fixed timing to the ignition setup window programming the options ignition fixed and

ign fixed.3. Added shortcut button to menu bar for context window4. Added connect to ECU or work offline dialog box on start up of AEM Pro5. Fixed problem where closing a file by disconnect following an attempt to change a

calibration online while the ECU is offline resulted in a GPF6. Added shortcut button for configure outputs to AEMPro7. Added message dialog following closure of injector change function window to open the

battery offset wizard if desired.8. Added AEM log icon in AEMPro. Also added ability to open a log file in AEMLog following

successful download of a log file.9. Modifications made to x axis of tabular maps such that the angle of text changes to better

utilize the available space according to the shape of the rectangle in which it fits. It also usesa bigger maximum size font.

10. Added notes indicating fuel pressure/injector throughput changes when affected.11. Fixed bug where resizing a table window resulted in the obscuring of the active site under

follow ECU.12. Fixed bug under full option window where hexadecimal values did not work.13. Fixed bug whereby crashes repeat if a table graph window is displayed when the associated

tabular view is not shown. Only noticeable if the current table site value changes.

14. Removed 'template save as window' from menu15. Under compare across different versions, copying a value into the current calibration failed

to remove the entry from the list. This occurred because the converted value isn't exactly thesame. Modifications made ensure the entry is removed as the conversion is as close aspossible.

16. Added use last folder option for storing calibration files.17. When saving a log file note now adds ECU name, version, date and time ahead of note text.18. Added programmable telemetry setup window: View | Telemetry Setup…



19. Added a Save and Load function to the internal logger setup dialog box. Preconfiguredsetups can now be saved and re-loaded.

AEM Log:1. Added a programmable filter function.



Setup Instructions:

1. In AEMPro go to File|Convert and select OK under the “Manual Conversion” option thenopen the .cal you want to convert.

2. Select the new file type by choosing the V1.19 option from the drop down list.



3. When the following message box appears, choose “Yes”.

4. When the following message box appears, use the assign button to assign:

A/C Clutch to A/C Output #1 andA/C Fan Speed to A/C Output #2

Select the options in each column and press the “Assign” button as shown below thenpress the “Finished” button. Next save the file.



5. Open the .cal file you just converted in AEMPro. Go to the menu Options|ConfigureOutputs. Select the output from the drop down lists associated with fuel pump control inyour application. Refer to your connection diagram to identify your fuel pump output control.Ensure the basic activation criteria are always met and that the fuel pump function isactivated. Pay special attention to the Road Spd criteria. Make sure this condition is alwaysmet. For example, if the Activation criteria for Road Spd is set to at least 255 MPH. Thismeans the fuel pump will never activate unless your vehicle speed is at least 255 MPH.Make any changes as necessary.

6. Go to the menu Options|Configure Outputs. Review all configured outputs for yourapplication. Ensure the activation criteria are appropriate. Refer to your connection diagramfor a listing of the outputs used in your application or use your old calibration file forreference.



7. The A/C control function was revised in V1.19. Go to Setup | Air Conditioner | Options – A/C. If you want to activate your radiator fan when the air conditioner is turned on,configure you’re A/C options as follows: Find the low speed radiator fan output as definedin your applications pin-out sheet and use this output to define both the A/C Fan Speed andRad Fan options as shown below. You must also turn off the low speed fan control LSX_Altoption. For example, if your low speed is defined as LS8, go to Options | Full List and turnoption LS8_Alt OFF. IF you don’t do this, the output will cycle when the A/C function is ON.



8. Go to Setup | Sensors | Manifold Pressure Sensor | Options – MAP Sensor. If yourapplication uses a 0-5V manifold pressure (MAP) sensor for the engine load input,select MAP voltage for the MAP Analog Input option.



9. Go to Setup | Sensors | Mass Airfow Sensor | 0-5V MAF | Options 0-5V MAF. If yourapplication uses a 0-5V Mass Airflow (MAF) sensor for the engine load input, selectMAF voltage for the MAF Analog Input option.



10. Go to Fuel | O2 Sensor Feedback | Options - O2 Sensor FB. If you are using O2FB,Select an appropriate value for the O2FB Cut Inhibit Option. Once any rev limiter isactivated, O2FB will be inhibited for this amount of time after the rev limiter is turned offagain. Recommend 200 ms. Select an appropriate value for the O2FB Minimum RPMoption. O2FB will be disabled below the RPM setting for this option.



11. Go to Setup | <<Advanced Setup>> | Anti-Lag Turbo Spool | Drag Race Anti-Lag |Options – Alt. Select an appropriate value for the Alt OK Below VSS Option. The Altfunction will be disabled above the vehicle speed defined by this option.



12. If your application uses automatic transmission control 94-98 Toyota Supra TTautomatic and 94-95 Ford Mustang GT automatic only, go to Transmission | Automatic |<<Advanced A/T>> | Options – Advanced A/T. Enable or disable torque converterlockup hysteresis by selecting or deselecting the A/T Gear Lock Hyste option. The A/TGear Lock Delay option can be used to define the lock/unlock delay time.



13. Now save your newly converted version 1.19 calibration file.

14. Before continuing, disconnect all injectors and coils (remove the harnessconnector). During firmware update, the EMS software does not control the outputsfor a brief period of time. This step is a safeguard to protect the vehicle’s hardware.

15. Turn the key to the ON position then connect to the EMS.

16. Go to ECU|Update EMS Firmware. Follow the on-screen instruction to update the firmware.The firmware update process is now an automated procedure. The software will check eachitem as it is completed.

17. When the window below is displayed, click Next twice then select the AEM15 v1.19b.fin file.



18. Click Next then when prompted to select the calibration file for upload, remember to selectthe file saved above.

19. The software will clear the current calibration file from memory.



20. The following window displays the status of the firmware upgrade. You may have to wait amoment before it begins. DO NOT INTERRUPT THIS PROCESS . DO NOT TURN OFF SWITCHED POWER. DO NOT ALLOW YOUR LAPTOP TO SHUT DOWN OR GO INTO STANDBY MODE. BE SURE LAPTOP BATTERY POWER IS SUFFICIENT OR USE A/C POWER.

21. The software will automatically upload the chosen calibration file.



22. Click close when each item is shown as completed.

23. IMPORTANT NOTE: When the firmware update and calibration file upload process iscompleted, cycle the vehicle power.

24. Re-connect all injector and coil wiring.

25. Connect to the EMS.



26. Go to Setup | Internal Logging and configure your internal logger setup as necessary. YourInternal Logger setup configuration must be re-defined after the file is converted.

27. Save your calibration file.

28. Start the car.

29. Confirm ignition timing by using the ignition sync function. Go to Configure|ECU Setup|SetIgnition and follow the on-screen instructions.

30. If any problems are encountered during this process. Compare your calibration file to theprovided AEM Base map for your application.
