    Ltrims Tables

    I am trying to isolate a problem in my LTRIM tables. It would be nice to be able to read this table, or at least figure out how/when the PCM changes cells.

    I know they are learned and stored.

    Re: Ltrims Tables

    In the Engine>Fuel there are two tables that show
    LTFT (FTC) cell boundaries by MAP and RPM. On my '02
    FBody the RPM boundaries for Mid and High are
    crazy high, meaning effectively I only have an 8-cell
    LTFT "map" instead of the 16 cells you'd expect from
    reading other 'net information. But, the info you will
    find (like there is a decent discussion going on on
    LS2.com, some on EFILive.com too) is useful visually,
    just boundaries "drift" based on the values your car
    has in these two tables.
