    TCC Mode

    I would like to see the TCC Mode display basis changed to
    a numeric code instead of mioxed alpha (Off, Locked, --3--,
    etc.) so that it will graph and export to .csv cleanly (.csv
    only gets 0 now). Bunch of people seem to be trying to
    figure out TCC lockup problems lately but the logs are
    not providing useful state info for me. I know when I was
    debugging my own misfire problem I had to use the table
    display real-time to see what I needed to see.

    If there are other "mode" values of a similar display nature,
    the same applies.

    If there are any "background" components that underlie
    the TCC actuation, access to these (e.g. misfire flags,
    other lock-suppress logic) would be swell to have in the
    scanner.

    This is what I need.
    I have a lock-up issue that I cannot figure out. there has to be something I'm missing or can not see.

    Still hoping for this to happen, I see the -3-, -4- etc. are now
    showing as "Apply Enable" and "Apply" and so on, but none of
    these will export to Excel and the TCC Mode can't be picked
    for charting, only viewed in the table display.

    I"m having a similar issue with the TCC lock up, particularly on cruise. I would definitely be interested in this type of change, or at least some sort of translation/help in creating a custom pid that is readable in .csv.

    While we are at it, more control over the TCC solenoid would be nice.

    I agree! Like the following:

    Cold Temp Enable
    TCC will not enable if Engine/Trans temp is below this value. It is most noticeable after a converter (smaller size, large stall) swap
    Coastdown/Decel TCC Unlock
    Some calibrations (mainly trucks) will unlock the TCC when entering coastdown or decel. Have the ability to disable this function or fine tune it.

    Was going to request that a couple days ago but didnt get to make the post. The stock values even change in some calibrations. I could swear the newer Grand Prixs allow lockup at 21*C and higher. While mine and a few older years of the same car lockup only at 26*C and higher.

    Coastdown/Decel TCC Unlock
    Some calibrations (mainly trucks) will unlock the TCC when entering coastdown or decel. Have the ability to disable this function or fine tune it.
    This would be sweet on cars. I have seen another table with access to TCC vs TP% lockup modifiers (not just the MPH tables we have now).

    97 Grand Prix GTP (not going to bother listing mods in detail) 1 messed up 97 PCM with about 30-50% of a 2003 calibration and parts of a few others.
