I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

T43 - PCA Pressure - How to log?

Hi Blokes,

Looking at the tune for my T43 6L80 auto, I've noticed the TCC Desired Pressure table [TCM 5672] is referencing something called PCA Pressure (PSI). I cannot see any channels that match this? Can anyone shed some light on what this value is or how to calculate it?

I have searched high and low and the closest thing that I can see is this on the HPT forums:

[TCC Line Pressure] = [TCC Regulator Gain] * [TCC PCS Pressure] - [TCC Regulator Offset]

[TCC PCS Pressure] = ( [TCC Line Pressure] + [TCC Regulator Offset] ) / [TCC Regulator Gain]

Thank you.
