Hi,
Just finished my transmission swap. (C7 GS with Katech stage 2 cammed engine, 555 WHP)
Updated the ratios in the trans menu. Only first 2 decimals though (original has 4 decimals)
No clutch slip, output trans shaft speed is good. Clutch position is a 0% and no moving when it happens. I calculated the ratios for each gear and I'm finding what I put in the ratios. I don't have any dips in the output trans shaft rpm when it happens.
I probably missed something in the tune... Any ideas ? I doubt me missing some minuscule digits in the gear ratios could cause this problem ?
Got the reduced power and reduce clutch usage message in 1st and 2nd mainly., even at partial throttle.

Log reduce clutch usage.hpl Easy to see when it happens. Timing gets cut like crazy, goes to like -10deg
Thanks for the insight
