I'm running a dual pulley Q5 3.0 Pulley Ratio (PR) of 3.1 with following MVPI2 mods, TCM rev limit under general to 7500 from 6950, change max mode counter to 255 (max for my version of OS, not the 65,535 newer versions of the 8hp most Audi's have), changed the shift maps to shift at 7000 rpm's in Aggression 3 shift maps 3, 8, 13, 23, 28 and under TM general changed torque limit gear based for normal to 500 and stall to 500. Life was good, I was getting WOT shifting at 7000 in sport/manual mode and AMAX was working.
Well fast forward to a week ago and I installed with a slightly large crank pulley 179mm -> 189mm, (PR 3.28) I data logged iat's, timing, knock and boost 3rd gear pull, everything looked good. I went out and tried run from a stop through the gears and both first and second gear short shifted around 5200, I know in some cases if there's wheel spin the trans will short shift but I don't believe the wheels were spinning. Traction control was off in both cases.
My question: other than wheel spin is there something in the tcm that could cause this behavior? I've looked at what I can log and I don't see it, could it be that I've changed shift maps? I don't see how to log which aggression and shift id that you're using with scanner. Any thoughts on where I could take a look.
Thanks in advance for any insight into this.
