Description

The COBB CAN Flex Fuel Upgrade Kit for 2018–2021 Subaru WRX 6MT delivers precise ethanol content monitoring through a seamless, plug-and-play solution. Whether you're chasing peak performance with E85 or simply want adaptive tuning based on fuel composition, this kit allows the COBB Accessport to deliver real-time Flex Fuel calibrations using CAN-based sensor inputs.

At the heart of the system is COBB’s CAN Gateway Module, machined from billet aluminum and designed to mount cleanly using an included bracket. This advanced module injects sensor data—such as ethanol content—into your WRX’s factory CAN system. The ECU then uses this data with COBB OTS maps or custom tunes to dynamically adjust performance.

Also included is the COBB CAN Ethanol Sensor Kit, which includes an ethanol sensor, quick-disconnect fuel lines, a mounting bracket, and a model-specific harness that connects to the CAN Gateway. This kit is purpose-built for 2018–2021 WRXs and is not compatible with earlier model years due to harness differences.

Install it with confidence and enjoy the performance gains of true Flex Fuel support, all without the complexity of custom wiring or ECU hacking.
