New to Injection - Guhl Motors

New to your injection? Start here!

This page includes all the information you need to get started with your injection, including what your injection comes with and how to set it up with your Fuel Tech ECU. Be sure to read all warnings, steps, and recommendations for the best experience.

R6 Standard Electronics with Stock ECU

***WARNING*** What coils should I use?

NEVER use 1999-2005 R6 coils with the 2006-2020 R6 electronics!!! Doing so will destroy the ECU!!! Using an ohm meter, measure across the 2 wire harness pins on the coil. The ’99-’05 coils will read near 0.5 Ω, and the ’06-’20 coils will read near 1.5 Ω.

‘08 R6 Moveable Stack Injection System (Standard for all)

60 or 65 PSI Fuel Pressure – Should be written on the ECU
Air temperature sensor to be zip tied to upper fuel rail outside of the car. (Inside the hood will produce a false reading) Current systems have an air temp sensor mount on the outside lip of lower airbox plate.
Barometric pressure sensor connected to lower injector sub-harness to be left un-capped.
Throttle position sensor(TPS) connectors are the same connectors. If when you start the engine and it revs up immediately, shut down the
engine and reverse the connectors.
The connector with two BLUE wires go the the backside of the throttle body.

‘03-’05 Yamaha R6 (Black and Silver)

Use ‘06 and newer (all black) Yamaha R6 coils.
Use ‘06 and newer (all black) intake boots.
Use Guhl pickup wheel. PN: 002-Y60B-PUWHEEL (Supplied separately)
Verify that the programming in the ECU is for the ’03-’05 engine.

Recommendations

1. Fuel Filters:

Strongly recommended: Use our fuel filters/elements (PN: FTR-0001).

2. Fuel Line Setup:

Route fuel lines to allow air filter changes without disconnecting any fuel lines.

3. TPS Sensors:

Generally, TPS sensors do not fail. NEVER adjust, move, or change a TPS sensor without first consulting us. Adjustment of the TPS will most likely result in having to send your system to us for re-calibration.

Instruction Sheet: GT6 Electronics with Fuel Tech ECU

All Engines

1. Fuel Pressure: Set to 60 PSI.

2. Coils: Use only the coils provided with the GT6 electronics package.

3. Air Temperature Sensor Placement:

Secure the sensor to the upper fuel rail outside the vehicle.
Avoid placing it under the hood, as it will produce false readings.
Note: If the injection system has a sensor mount, do not move the sensor.

4. MAP Sensor:

The MAP sensor is now integrated into the Fuel Tech ECU and no longer located on the throttle bodies.
Connect the vacuum line from the throttle bodies to the nipple on the rear of the ECU.

5. Sensors (Yamaha R6 Only – TPS and APS):

The TPS (Throttle Position Sensor) is located on the inside end of the throttle bodies.
The APS (Accelerator Position Sensor) is located on the front of the throttle bodies.
Important: These sensors use identical connectors. Ensure they are plugged into their correct locations.

6. Software Installation:

Download the Fuel Tech FTManager software from this link:
https://files.fueltech.net/software/previous/ftmanager-v491.zip
Important: This is the correct version. Do NOT upgrade to a newer version if prompted.

7. TPS Calibration:

Calibrate the TPS using the FTManager software or the Fuel Tech touchscreen dash after the
system is operational.

8. Data Logging Memory:

Clear the data logging memory regularly. It can store data for about one weekend of use before
becoming full, which stops further recording.

‘03-’05 Yamaha R6 (Black and Silver) Specifically

1. Intake Boots: Use ‘06 or newer all-black intake boots.

2. Pickup Wheel:

Install the Guhl pickup wheel (PN: 002-Y60B-PUWHEEL), supplied separately.

3. ECU Programming: Verify that the ECU is programmed specifically for the ’03-’05 engine.
