ECU Master EMU - Flex Fuel Sensor; Parameters

FLEX FUEL SENSOR
A FlexFuel sensor measures the ethanol content of the fuel as it passes through the fuel system.
Information about ethanol content can be utilized by the ECUMASTER EMU to adjust the fuel
dose, ignition advance, or boost pressure. The EMU supports GM/Continental frequency sensors.
The FlexFuel sensor should be connected to the CAM#2 input or to VSS input if the CAM#2 input
is used for a camshaft position sensor. To activate the FlexFuel sensor, the Enable FlexFuel
parameter should be checked and Table switch mode should be set to FlexFuel blend in options
menu Other/Tables switch.
