Closed loop fueling uses the narrowband O2 sensors and fuel trims to make corrections Open loop fueling uses a wideband 02 sensor to make corrections MLHFM - Closed Loop This algorithm is roughly based on mafscaling. Algorithm The average of your LTFT and STFT corrections at each voltage for ...
Unplug the electrical leads running to the O2 sensor. Step 5 Remove the O2 sensor by placing the O2 sensor removal tool over the end of the sensor and turning the sensor and removal tool counterclockwise with a socket wrench.
