Torque Management contribution to the final ignition timing spark advance value.
This PID will monitor the final retard value for the sum of the following three torque management modules.
1 - Transmission Torque Reduction. (GM.EST_XMSN_DMA)
2 - Traction Control. (GM.EST_TRAC_DMA)
3 - Brake Torque. (GM.EST_BTM_DMA)
This value is controlled by the "Torque Limiting" and "Traction Control" calibrations in the EFILive Tuning Tool.
The spark retard tables in the "Traction Control" section controls the final amount of spark that will be retarded based on the above 3 PID's.
