Installation Instructions
This kit is designed to provide a way to Datalog and monitor the ethanol content of fuel on most new Subaru Vehicles. Our proprietary controller reduces complications by generating its own onboard 12V supply to power the sensor. This reduces wiring, installation time, and improves reliability. Our system also properly references the ECU 5V power to provide the most consistent and accurate data. We have supplied hose assemblies for both the 2008+ STi and WRX in a single kit to reduce complication and confusion when ordering. The kit also comes with a custom wiring harness that can be detached from the controller to make any troubleshooting and repairs simple and painless.

Since the cars only have two TGV plugs capable of receiving inputs, you cannot run our Secondary Injection Controller, Flex Fuel Sensor, and Fuel Pressure Sensor kits all at the same time. You can only run a maximum of two of these three items. The SIC can be wired as power only in order to utilize all three but a custom harness must be made.
 
Compatibility:
2008 - 2021 STi
2008 - 2021 WRX
 
Tuning:
Works with most fuel management systems, but the car must be tuned specifically to run flex fuel. This will not work with Cobb “Green Speed” tunes. They have just released a new flex fuel option that is compatible with Green Speed and we will be doing testing to understand what we will need to do to ensure compatibility. Please work with your tuner to understand what options they have to tune your car, as compatibility may vary from tuner to tuner.
This kit has the same voltage output as other popular kits. Returning your car most likely will not be required if you are just replacing another brand of flex fuel controller.
