    Default Ls1b ltft 0%

    I remoted in to a buddys truck last night and was trying to figure out a few idle issues with his 416.
    Had him put new oxygen sensors in since they were throwing codes for heater issues and performance.
    What i couldnt figure out was what keeps LTFT from working? STFT were in the -15 to -20% range. I doubled checked his tune to a stock tune with the same operating system and after doing a compare there were no differences i could find that was different for the LTFT's.

    Include the pids HO2S11 and HO2S21 (they are the O2 sensor voltages) in you logging.
