Fitment Information:

2008-2021 Subaru STI

Please note: This kit is specifically designed to work the latest Cobb “Green Speed” tuning packages. Please work with your tuner to understand what options they have to tune your car as compatibility may vary from tuner to tuner. If you are looking to replace older flex fuel kits without the need to retune, take a look at iBR’s FLX01 Kit or FLX01 Upgrade Kit.

Features:

The I Build Race Cars FLX02 Flex Fuel Upgrade Kit has been designed to provide a way to data log and monitor the ethanol content and be compatible with Cobb’s latest version of their tuning software. iBR’s proprietary controller reduces complications by generating its own on board 12V supply to power the sensor. This reduces wiring, installation time and improves reliability. This system also properly references the ECU 5V power to provide the most consistent and accurate data. 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.

• Replaceable wiring harness that will be sold separately
• Automotive grade wiring
• No need for 12v supply from boost control solenoid circuit
• Installation can be done from the top with no need to crawl under the car
• Properly referenced analog output from ECU 5V for better accuracy
• Potted housing with solid pin connector for the ultimate in durability
• Tuning is required

Included in this kit:

• FLX02 Flex Fuel Sensor Controller
• Wiring Harness

This kit is compatible with iBR’s standard FPS01 Fuel Pressure Sensor kit which is available to purchase separately and is a great addition when you are pushing your fuel system to its limit with the higher flow rates of E85 mixtures.
