Chevrolet Performance Flex Fuel Harness

CHEVROLET PERFORMANCE FLEX FUEL HARNESS - 13352241
Determining actual ethanol content of E85 is essential to maximizing ignition timing, higher compression, and horsepower. Chevrolet Performance flex fuel sensor harnesses connect your GM sensor, which measures the ethanol-gasoline composition of the fuel used in your flexible fuel vehicle. In order to adjust the ignition timing and the fuel quantity to be injected, the engine management system requires the percentage of ethanol in the fuel. These electrical harnesses support a signal circuit which carries the ethanol percentage and changes the output signal accordingly. Fits flex fuel vehicles only with GM sensor part numbers 13577394, 13577429, or 13577329.
