    Logging TCC slippage

    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)

    Never tried that and no clue if can be done. I would think it needs input/output shaft speeds... and or turbine speeds. Interesting question and curious what the experts will say.
