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.
This Cobb Flex Fuel Package is an upgrade kit if you already own a Cobb stage 1+ Power Package. This includes 1050x Injectors, upgraded fuel pump, fuel rails and lines, throttle body coupler, turbo inlet, colder range spark plugs, Cobb NexGen ethanol content sensor, and 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 2+ Flex Fuel ONLY. Aside from the Stage 2+ OTS map, ANY Flex Fuel implementation will require custom ECU tuning.
Fits all 2015-2021 Subaru WRX STI equipped with an existing Cobb Stage1+ Power Package.
