Introduction

The Centurion Diagnostic Software is a user-friendly software tool able to diagnose engine and system

problems.

This Windows-based program was designed to communicate with a wide variety of Engine Control Units (ECUs).

The interface between the ECU and the PC is a Vehicle Communication Module or VCM. The user interacts with

the Centurion PC software, Centurion communicates with the VCM and the VCM communicates with the

vehicle.

How it Works

The ECU is a specialized small computer that interacts with and controls various vehicle sensors and solenoids.

These sensors and solenoids include the temperature of the motor (Harleys head temperature sensor), outside

ambient temperature and pressure (altitude), throttle position (TPS), engine speed (RPM), load (kPA or Manifold

Absolute Pressure/MAP), and many more. The ECU processes all this data and makes adjustments so that the

vehicle performs as it is programmed.

Centurion diagnostics gives the user the ability to interact with these ECUs to improve, repair, or monitor the

vehicle.

About this Manual

This manual is organized by chapters to assist novice users with getting started. Many topics covered in this

manual are also covered in the help menus available in the program itself.

1. Setup and installation

1.1 Where to get the Software

The software is available online as a download from the TechnoResearch website or from the CD that is

distributed with VCM products.

Insert the CD-ROM from TechnoResearch Inc. into the DVD/CD-ROM drive of the computer…

OR download from our website (www.technoresearch.com , go to Support > Downloads).

Scroll down to the Centurion heading:

6

1.2 Install Centurion-U

After auto-run, press install button and follow installation prompts.

1.3 Run Centurion

Double-click on the Centurion-U icon on the desk top to run the program. This will install the USB security

hardware key driver necessary for Step 1.4

1.4 Insert Security Key into USB Port

This is a portable licensing system. Plug this USB license key into any computer and the freely downloadable

Centurion software will run. This lets shops utilize the software through multiple computers, simply by moving

the hardware between them.

Insert the provided pre-programmed USB software license key, (color matched for application), into the USB

port of the computer. This will enable the software to run.

7

• Remove one software license key before attempting to use another. Only one software license key may be

accessed at a time.

1.5 Connect USB Cable

These USB cables are standard and common. No unique cables are needed to connect the VCM to the computer.

The VCM-TR3 also has Bluetooth 2.1 as an option over the USB cable.

Connect the mini USB or USB cable to the Vehicle Communication Module (VCM). The module is shown below,

with the mini USB port on the right side of the VCM. Connect the other end to the PC’s second USB port.

VCM-TR1 VCM-TR3

1.6 Power up the Centurion

The Centurion Super Pro Kit provides cables to connect directly to the OBD ports on all Harley Davidson models.

These also have individual part numbers and replacements can be purchased if needed

Connect the Vehicle Communication Cable to the port on the other end of the Vehicle Communication Module.

Connect the other end to the motorcycle’s data link connector. Please consult the motorcycle user manual for

motorcycle data link port locations.

To avoid damaging the cables, keep them clear of the exhaust

.

1.7 Power up to Automatically Install Drivers

The VCM-TR1 is powered by the battery of the motorcycle, just make sure the ignition is ON and the RUN switch

is ON. The VCM-TR3 can be powered by the battery of the motorcycle or from the computers USB port. The

green light on the VCM should be lit is power is being received. Once the VCM is powered and the USB cable

8

attached to computer, the software will start a search for the cable drivers. In XP and older versions of

Windows, the computer will prompt the user to perform additional steps:

1. Select the folder called ‘USB 2.0 Cable Drivers’ on the install CD.

2. The software will then find and install the drivers.

In more recent versions of Windows, on a PC that is connected to the internet, the drivers will be located and

installed automatically. If notifications are enabled, the user will see the status of the driver installation in a chat

bubble in the lower right corner of their screen.

1.8 Update the Centurion Software

Feature additions, changes, fixes, and updates are a part of our commitment to delivering the best possible

product to the user. Keeping the software up to date, via the internet updater, is the best way to ensure that the

user has the best possible experience with their software.

After the Centurion software is installed, run the updater to get the latest program versions, including the

newest calibrations and manuals. To update: Click the ‘Updater’ icon at the bottom of the opening screen. This

will launch a separate program that will download all the updates and put them in the correct folders. This often

requires no additional setup steps to be successful. If issues do arise, it may be necessary to disable the internet

firewall on the computer and/or set exceptions for updater program.

3.5 Active Test

Sends commands to the ECU making it attempt to active parts of the motorcycle. This aids in quickly identifying

WHERE the failure is or WHAT is failing. Example: Turn signal switch does not activate the turn signals.

Command the ECU to turn on the LEFT turn signal via the appropriate CENTURION ACTIVE TEST. If the ECU can

turn on the turn signal lights, the problem exists between the switch and the ECU, not the ECU and the light.

This window provides the selection of Active Tests. An Active Test is an ECU command that temporary causes an

effect on the vehicle, such as turning on a fan for a few seconds or activating a turn signal. These commands

differ from Active Settings in that the changes do not persist beyond the testing phase. The Centurion’s Active

Tests are filtered by ECU and limited to what the ECU being tested actually supports. Some ECUs differ within

the brand and cannot be filtered, the Centurion will indicate if an attempted test is not supported by the ECU

variation present.

3.5.1 Active Test Definitions (HD Delphi)

System: System relay, fuel and coolant pumps.

LED: ABS, battery, cruise, engine, 6th gear, low fuel, security tell tail, security lamp and alarm LEDs.

Speedometer: Tachometer and speedometer.

ABS Solenoid: Front & rear/apply & release, ABS and rear pumps.

TSSM: Left and right turn signals.

Actuators: ACR and throttle actuator.

17

ACR: Air compression release.

EITMS: Engine idle temperature management system.

Fans: Cooling fan.

Adjust Idle Speed: Change and test idle speed.

Injectors: Injectors 1 and 2.

3.6 Active Settings

These are advanced features. Many Harley repairs and modifications REQUIRE the use of advanced diagnostic

tools. Centurion is feature rich and easy to use. Simply click the icon and select the task from the dropdown

options.

This window provides the selection of Active Settings. An Active Setting is an ECU command that creates a

lasting change to the vehicle, such changing a Key FoB, bleeding the ABS, or clearing DTCs. These commands

differ from Active Tests in that the changes persist beyond the testing phase. The Centurion’s Active Settings are

filtered by ECU and limited to what the ECU actually supports. Some ECUs differ within the brand and cannot be

filtered before connection, the Centurion will indicate if an attempted procedure is not supported by the ECU

variation present.

18

3.6.1 Active Settings Definitions

DTC: Read and clear current and historic diagnostic trouble codes.

Quickly read trouble codes from multiple modules on the motorcycle, view the results, and clear the codes… all in

Glossary

ECM/ECU (Electronic control module/unit): This is the brain of the motorcycle; it makes calculations based

on inputs coming from sensors mounted all over the engine.

WOT (Wide open throttle): The maximum opening of the throttle valve.

AFR (Air fuel ratio): The relationship of parts of fuel to the parts of air. 13.0(air) to 1(fuel) usually makes the

best power, and 14.6 is considered “perfect” air fuel ratio. This would be the AFR to get an ideal burn

(theoretically). This would be at perfect atmospheric conditions and temps, with a perfect atomization which is

almost impossible.

MAP (Manifold absolute pressure): These sensors measure barometric absolute pressure in the intake

manifold. By calculating the mass of the air going into the engine, air temperature, and the rotations per minute

of the engine, the engine’s ECU can determine the density of the air flowing into the fuel mixture. The ECU can

then adjust air flow or fuel flow.

CKP or CP (Crank position sensor): This sensor tells the ECM when to fire and inject fuel depending on how

fast the engine is running in Revolutions Per Minute.

IAT (Intake air temperature): The ECM calculates how dense the air is from this input.

ET (Engine temperature): The ECM uses the signals from this sensor to determine if the engine is at operating

temperature, or warming up.

Fuel Pressure Regulator: A mechanical device usually operated by vacuum form intake manifold that controls

fuel pressure. It returns excess fuel from the fuel pump back to the fuel tank.

Fuel Injectors: The fuel injectors are electric valves that open and close to deliver fuel in spray form to the

cylinder. They are controlled by the ECM to precisely deliver the correct amount of fuel at every engine speed or

RPM and any given load. The time of injection is also known as the injector “pulse width” and is measured in

milliseconds. Injectors are rated by their flow rate – such as in gm/sec, l/hr or grams per second.

Electric Fuel Pump or Fuel Pump: A 12-volt high-pressure fuel pump, usually located in the fuel tank, but it

can be located outside as well. It supplies pressurized fuel to the fuel injectors.

IAC (Idle air control): An electric valve that’s threaded, to open and close as needed to let air into the engine

for startup and idle operation when throttle valve is closed.

Closed Loop injection system: This circuit has 2 Oxygen sensors. The information on the difference of how

much is coming out of the cylinder is relayed to the ECM and then adjusts the amount of fuel injected by

shortening or lengthening the time the injectors are open.

O2 (oxygen) sensor: This tells the ECM how much oxygen is in the exhaust mixture so as to have the correct

mixture. Anything under 14.7 is considered a rich mixture and anything above 14.7 is considered a lean mixture.

RPM (Revolutions per minute): Used to measure engine speed.

TPS (Throttle position sensor): Measured in percentages (0 to 100) or Degrees (°) and/or Volts (V).

DDM (Drop down menu): selection of parameters available for a field.
