Okay, This thing has me stumped. I have spent all of my free time over the last four days scouring forums and making changes to the tune to no avail. I have contacted Circle D as well as my local tuner and tried their recommendations as well.
Here the situation:
2012 Caprice PPV
L92 short block
6L80 trans
BTR Stage 1 N/A cam
Circle D 278mm 3000 stall HP converter
CAI and axle back exhaust
TCC disabled in 1-4
TCC desired slip = 0 in all tables
TCC ramp table = all cells increased +90psi
Max Pressure = 138.2 all cells
Regulator gain= 1.5 (have tried 0, 0.5, 1, 2 and 8 as well, no change)
Regulator offset= 90psi (have tried 40, 60,and 110 no change)
TCC desired slip= 0 on all tables
TCC adapt MIN&MAX= 0 ( have tried 0/100, 50/100, 100/100, no change)
I have also tried maxing the misfire tables(not on this tune) with no change.
The TCC line pressure ramps in to ~45psi to lock the clutch, bleeds off to ~20psi, clutch starts slipping up to ~50rpm, TCC pressure ramps back to ~45psi and clutch locks. This cycles approximately every 2 seconds while cruising. It is not affected by speed. I have locked the TCC through the VCM Scanner and it ramps to 594psi and holds. The only changes that appear to have had any affect is setting the desired slip tables to zero, as before it would slip even further before the TCC line pressure would increase and re lock. I have attached a log with the issue as well as the current tune.
ANY help is greatly appreciated!!
