Hey guys, I am new to tuning and just got an MPVI2 to tune my 2011 CVPI.

So far I have had good luck changing transmission parameters, but now I am stuck on tuning the torque converter lockup clutch. It seems that my changes work when just driving around, but at WOT it will always lock the TCC about 1 second after the 1-2 shift, and the clutch always locks rather slow and sluggish. I have tried adjusting the TCC lockup delay, the lockup rate, and the scheduling but nothing seems to make any difference. Is there some setting that I might be missing?

BTW the car has 3.73 gears now, and the transmission has a Transgo reprogramming kit. It drives great and performs well, I just cannot seem to be able to change the TCC parameters. My current tune is attached.

Any help would be appreciated!
