Next time you log a wide open shift with PCS1 recording, look at the shift pressure table and use the gain + offset to see how close it is...
I presume PCS A is the TCC solenoid. I have no idea of the gain / offset of that valve. I had started to make some rough correlations but gave up as I got the lock up of my stall perfect and realised that rabbit holes age me faster.
What I can say, is that the desired pressure table works and is well worth playing with, especially if an aftermarket stall is fitted. After all the fucking around I done with this table, in the end I found going back to OEM and moving everything 5 columns left and turning off TCC adapts worked best for me.
