Subaru WRX Flex Fuel Kit - COBB - 15-17. This package upgrades earlier COBB ethanol sensor setups to the CAN-based Flex Fuel solution for 2015–2017 WRX, with added fuel pressure integration.
By bringing ethanol content into the factory CAN network, your tuner can enable true flex-fuel operation with a COBB Accessport and the proper calibration. This setup lets your tune adjust for pump gas, E85, and blends in between, while fuel pressure data improves monitoring and diagnostics. Vehicle-specific components keep the installation tidy and straightforward for long-term reliability.
