Innovate 39070 (E85) Flex Fuel ethanol content sensor

This Ethanol Content Sensor measures the ratio of ethanol to petrol in a flex fuel vehicle. In order to adjust the ignition timing, fueling and boost levels, the engine management system requires information about the percentage of ethanol in the fuel.

The sensor is fitted to the vehicle’s fuel return line anywhere between the fuel pressure regulator and the fuel tank.

Using this information, the ECU can make necessary changes to the engine’s tune (ignition timing, fueling, boost pressure etc.). Even on applications where only one ethanol / petrol ratio is ever used, this sensor can still be very useful for monitoring and data logging purposes.

Electrical connector not included.
