Link G4 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.

A digital output signal is produced by this sensor, which can then be used by Link's ECUs (with appropriate flex fuel functionality) to determine both the ethanol content and the fuel temperature using just a single digital input on the ECU.

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.

All our ECUs are compatible with this sensor. This includes our Link G4+ WireIn and PlugIn ECUs, as well as Vi-PEC i44 / i88 plus the latest Vi-PEC PlugIn models.

3-Pin electrical connector included. Electrical connection consists of +12V, ground and signal wire.

Available with either AN-6 fittings or Push-Lok fittings at no extra charge.
