I have a 2007 Z06 with an A4 conversion. It runs a PCS TCM for the A4.
I used to log TCC slippage on my 05 A4 which proved to be very useful on the dragstrip.
Question is: what parameters are metered in the stock PCM that arrive at the TCC slippage numbers? and.... Can a PID be written that would allow me to log Tcc slippage even though the stock PCM doesnt usually see it?
Anyone ever tried this? I don't know what sensors are used to calculate the slippage.
Some obviously are :
engine RPM
Diff speed??(maybe)
Tail shaft speed???(not sure)
