The COBB CAN Flex Fuel Upgrade is an advanced ethanol-content sensing and integration system engineered for the 2017–2020 Ford F-150 Raptor EcoBoost platform. This kit enables your Raptor to run flex fuel (E85 or ethanol blends) by accurately measuring fuel ethanol content and feeding that data into your vehicle’s ECU through the COBB CAN Gateway. When paired with a compatible COBB Accessport and calibration, the system allows the engine management to optimize fueling and timing in real-time for different ethanol percentages, unlocking more power and safer high-boost operation. Designed as a plug-and-play upgrade with a billet aluminum gateway module and vehicle-specific harness, it’s ideal for enthusiasts pursuing performance gains, tuning flexibility, and the ability to switch between pump fuel and higher-ethanol blends.
