Description

The COBB Tuning Flex Fuel Package (315F03) is a computer and sensor kit designed to enable flex fuel capabilities for your Subaru WRX or STI. This package includes both an Ethanol Sensor Kit and a Fuel Pressure Sensor Kit, allowing your vehicle's ECU to accurately read and adjust to varying ethanol content in your fuel. The system is designed to work in conjunction with the COBB Accessport V3 and COBB Custom Features, providing advanced tuning options for optimized performance. This package is specifically engineered for 2008-2014 Subaru WRX models and 2008-2016 Subaru STI models. It provides the necessary components to integrate flex fuel monitoring and adjustment capabilities, enabling your vehicle to run on a mixture of gasoline and ethanol (such as E85) without requiring manual fuel system adjustments. The inclusion of both an ethanol sensor and a fuel pressure sensor ensures comprehensive data for precise tuning. Please note that this product has been discontinued by COBB Tuning and is no longer available for purchase.
