Flex Fuel Ethanol Sensor Kit

A complete plug and play solution enabling users to convert their supported Subaru WRX or STI to a Flex Fuel configuration. This is the easiest to use and most sophisticated Flex Fuel kit on the market. Utilizing OEM fuel and electronic connectors, the Ethanol Sensor Kit measures the ethanol content of fuel being fed to the motor. That data is then converted into a signal that the ECU can use for adjusting calibrations and to be displayed on a custom Accessport monitor.

WHY?

The Flex Fuel Ethanol Sensor Kit is a requirement for converting your supported Subaru to a Flex Fuel configuration. The Ethanol Sensor Kit measures the ethanol content of fuel being fed into the motor and converts it into data that can be utilized by the car's ECU. Flex Fuel OTS maps will be available for Stage 3 ONLY starting 1/2016 or 2/2016. You can also source a Protune from a custom tuner.
