    Same setup as AutoVE (open loop), but with these differences:
    - B0120 set to 400,
    - MAF enabled,
    - use B5001 BEN map to paste/multiply into B5001 MAF table.

    You want to do it in open loop because you don't want the trims to correct ahead of you.

    and there are other threads.

    No...not necessary.

    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    Typo Howard?
    C2901/C2903 should be set back to stock to re enable the maf. Resetting the Mil light in C6003 however is not really necessary.
