    TCC Desired Pressure

    I would like to change some TCC settings for my L20/6L90 swapped 1993 S10 Blazer.
    The engine and transmission are from a 2014 Express van, and it is a E38 ECM.
    I can?t understand the ?TCC Desired Pressure? (TCM 5672).
    Some values are set to zero, and max value is 52. The PCA range is 0-168 Kpa.
    All instructions I have looked at, shows PCA range 0-1600 Kpa.
    I would like to enter similar values as a 2012 Camaro ZL1, where the values are set to 79-1330 Kpa.
    Can someone explain this difference in PCA range? I guess I can?t just copy the ZL1 values and paste it to my tune, as long as the range mismatch?
    Thanks,
    Roy
