The gateway supplies an ethanol content data stream to the ECU, rather than a voltage. The ethanol sensor calibration table does not need populated and is not referenced. The calibration is predefined in Gateway code, so it is imperative COBB Gateway ethanol sensors be used with the Gateway system to avoid incorrect ethanol data.
When using the COBB CAN Gateway for Flex Fuel there are only a few steps.
Since the gateway automatically configures the sensor used, no sensor calibration is required, however this will only work with the specific COBB/Autometer 150 psi Sensor. Using any sensor with different calibration will result in incorrect values for fuel pressure.
