Description
Upgrade your fuel monitoring and tuning setup with the COBB Tuning CAN Flex Fuel Upgrade for the 2015–2017 Subaru WRX. Designed for compatible vehicle configurations, this upgrade package includes the module, wiring harness, mounting bracket, and ethanol sensor to support integration with an eligible COBB Flex Fuel system.
Flex fuel technology measures the ethanol concentration in the fuel, allowing a compatible engine management system and calibration to account for changes in fuel composition. Ethanol content can vary between fuel blends, making accurate monitoring important for vehicles configured to use different ethanol concentrations.
The COBB Tuning CAN Flex Fuel Upgrade is intended for compatible 2015–2017 Subaru WRX applications and includes several key components needed for the upgrade. However, compatibility depends on the vehicle's existing hardware, ECU support, tuning software, and calibration. Confirm whether your vehicle requires a previous-generation kit or additional components before purchasing.
