Hi,
i recently saw on part throttle acceleration, that the transmission torque limits are pulling around 15° timing until the TCC is locked, {GM.EST_XMSN_DMA} is logged, see attached file.
Usualy the B1902 is responsible for the amount.
Is there an other way to avoid this - exept altering this table and why this happens with unlocked converter only?
What other subsystems use B1902 and are affected while changing the table?
The 411 with 12221588 OS is used, are the other possible OS working the same?
All drivetrain/tranny torque limits in the .cal are already cut off or set to max.
The engine and the whole drivetrain were build to have the stock hp more than doubled (:grin:), and so it is important for the A4 (LevelVI) reliability to keep the torque reduction for the shifts and the abuse modes fully functional.
Regards
Marco
