    Default How to eliminate CL/LTFT/STFT

    Hey Guys,

    How do you completely disable CL/LTFT/STFT (AutoVE ) I don't want the wideband read stoich .

    My goal is to Run Full OLSD without going through COS

    is that possible?

    B3801 (LTFT correction): set to Disable.
    B4205 (CL temperature enable): set to max temperature.
    B4206 (STFT correction in OL): set to Disable.

    if your tune does not have B4206, then make sure there are no stoich cells in B3605.

    ( if you're running an LS1B COS, then make sure there are no stoich cells in B3647 and B3649 )


    Yes, you can run OLSD with the OEM OS (i.e. non-COS)... you won't get adaptive spark (it will run from LO Spark table), and if your OS has a Backup VE table it will run from that (i.e. not the Main VE table).



    And, you must make sure that it is running in SD by observing the immediate presence of a MAF DTC.
