Description
Unlock the full tuning potential of your 2015–2017 Subaru WRX with the COBB CAN Flex Fuel Upgrade Kit. This plug-and-play solution brings seamless ethanol integration to your WRX by utilizing COBB’s billet CAN Gateway and Ethanol Sensor Kit. Designed specifically for 6MT models, the system sends real-time ethanol content data directly to the ECU for full Accessport integration and Flex Fuel calibration support.
The precision-engineered CAN Gateway Module is housed in a billet aluminum case, mounted cleanly using a custom bracket. It allows aftermarket sensors—like the included ethanol sensor—to communicate over your vehicle’s CAN system. Paired with a model-specific wiring harness, the CAN Gateway installs with ease and OEM-like fitment.
Included in this upgrade is COBB’s CAN Ethanol Sensor Kit, which features quick-connect fuel fittings, a mounting bracket, and a harness that seamlessly links to the CAN Gateway. This kit is compatible only with 2015–2017 WRXs. For 2018–2021 models, a different harness is required.
Whether you’re running E30 or E85, this kit ensures the ECU has the precise fuel composition data needed to optimize performance, boost safety, and support COBB OTS or custom tuning.
