High ethanol content (E85) fuels can provide substantial power gains when tuned appropriately. The key to harnessing that power is COBB's flex fuel kit. The kit consists of an ethanol sensor, an ethanol signal converter to communicating the sensor data to the ECU, hoses and adapters, electrical harnesses, and mounting bracket.
