Fitment: This kit is made for 2008 - 2021 Subaru STI. It's designed to work with the latest Cobb “Green Speed” tuning packages. Note that compatibility may vary among tuners, so consult your tuner. If you want to replace old flex - fuel kits without retuning, check iBR's FLX01 Kit or FLX01 Upgrade Kit. Features: The I Build Race Cars FLX02 Flex Fuel Upgrade Kit allows you to data - log and monitor ethanol content and is compatible with Cobb's latest tuning software. iBR's unique controller creates its own 12V supply for the sensor, reducing wiring, installation time, and boosting reliability. It references the ECU 5V power for consistent and accurate data. The custom wiring harness can be detached from the controller for easy troubleshooting. It also has a replaceable wiring harness (sold separately), automotive - grade wiring, no need for a 12V supply from the boost control solenoid circuit, top - side installation, proper analog output from ECU 5V for accuracy, a potted housing with a solid pin connector for durability, and requires tuning. Included: FLX02 Flex Fuel Sensor Controller, Wiring Harness, Continental Flex Fuel Sensor, Flex Fuel Sensor Bracket, and Fuel Lines. This kit is compatible with iBR's standard FPS01 Fuel Pressure Sensor kit (sold separately), great for high - flow E85 mixtures. WARNING: (http://www.p65warnings.ca.gov)
Using this I Build Race Cars FLX02 Flex Fuel Full Kit is easy. First, check if your car is a 2008 - 2021 Subaru STI. Then, work with your tuner to make sure the kit is compatible with your car's tuning. The installation can be done from the top of the car, so you don't need to crawl under it. When it comes to the wiring, the controller has its own 12V supply, reducing the complexity. The wiring harness can be detached easily for any repairs or troubleshooting. Remember, tuning is required for this kit to work properly. As for maintenance, keep an eye on the sensor and wiring. The potted housing with a solid pin connector makes it durable, but if there are any issues with the replaceable wiring harness, you can buy a new one separately. Also, if you're using high - flow E85 mixtures, consider getting the iBR's standard FPS01 Fuel Pressure Sensor kit for better performance.
