I started tuning a buddies 09 GT today after adding some new mods. He has a cam, heads, 3.45s, stock converter, headers/no cats exc. Not having any trouble doing the engine tuning since he has a wideband, but the TCC seems to be having some major issues! I haven't even been able to dial in the engine tuning because its so bad. I can barely get it rap out a single gear with out the the trans flaring heavily through out the RPM range. I have a lot of trans changes currently. Even when i put the trans portion of the tune back to stock, still flares bad (not shift point flares, they seem to be TCC locking and unlocking flares). I have the tune adjusted for his tire size and 3.45 gears. Might just be a simple TCC parameter change, but im not having any luck.
Quick screen shot below (you can see the RPM flares in the chart display)
Also, flares did NOT happen at all before the cam, heads and 3.45 gears...
Any ideas?
