I'm getting Torque management spark retard (advance) with an M6 Gen 3 P01 ECM car, (1994 LT1-383).
I cannot find the code in the ECM that commands it. I have everything zero or turned off (as far as I know).
But obviously something has escaped me. Maybe it's phantom and not really there.
Where have you found ?
I have a log and I labeled it TM Spark. It comes it mostly during steady cruise and steady throttle.
If I worked it right I have the tune attached and a data log attached.
Didn’t look, but could be AC system

AC Bump Torque Spark? Yes the AC was running during the drive data log. Have you disabled this feature and can you feel the difference?

Curious, your module control voltage is low, were you on battery?
