    Default Spark Torque

    Trying to log my spark. GM.EST_TRQ_DMA is combination of three pids:GM.EST_XMSN_DMA, GM.EST_TRAC_DMA and GM.EST_BTM_DMA.

    TRQ was active on deceleration so I tried to log the four pids individually.

    Can not get the BTM to load in black box, but XMSN loads twice.

    Also when TRQ is active, up to 17deg there is no effect on spark. When there is no activity for TRAC - XMSN is active up to 15deg but also has no effect on spark. TRQ and XMSN are not active together but TRQ is suppossed to be a sum of three.

    As soon as I find my zipper I'll attach the log file.

    What am I missing? Are these pids for automatics only?

    Crap, I think my zipper is busted. Anyone intersted in the zip attach I'll mail it.

    Does anyone have a clue as to how all this torque can be showing at idle with no reduction in spark? I seem to run mostly on high spark table with decreases from IAT.

    Am trying to keep TCC active and eliminate all other transmission torque limiters.
