Cobb Flex Fuel Complete Package 2008-2014 WRX, 2008-2021 STI

  • Harness the power of ethanol, while maintaining ease of ownership and the flexibility to fuel up where and when you want. Flex Fuel is a combination of hardware and software that will allow your car to run on any mixture of gasoline and E85 fuel. A fuel pressure sensor and ethanol content sensor will deliver fuel quality information back to the ECU, where it will adjust boost, fuel, and timing parameters accordingly. It's a whole new world of high performance.

    The Cobb Flex Fuel Package is a complete kit that includes an ethanol sensor as well as a fuel pressure sensor. Utilizing COBB custom features along with this package, both fuel pressure and ethanol content values are able to be sent to the ECU and monitored via custom Accessport Monitors.

    Cobb Off-the-Shelf (OTS) Flex Fuel maps for AccessPort should be available at beginning of February or sooner. Flex Fuel OTS maps will be available for Stage 3 ONLY. Aside from the Stage 3 OTS map, ANY Flex Fuel implementation will require custom ECU tuning.

    Note that we recommend a MINIMUM injector size of 1000cc for Flex Fuel implementation, and a fuel pump upgrade is REQUIRED.
