    Searched for this info but could not come up with any solid info. The tcu
    in my 99 360 is a cfc201f.05 part #191701. My clutch engaged at a lower rpm
    just off idle when i bought the car years ago, now i noticed that the
    engagement occurs at a higher rpm, somewhere around 1500 to 2000.
    I am assuming this is due to some clutch wear after about 5000 miles.
    I would like to adjust the pis. Could anyone tell me if this could be done with
    the x431?

    I have version X431 V10.85 and it cannot connect to this generation of TCU.
    Don't know if it has been solved on later versions but I doubt about it.

    Thanks Eric
    I know from reading the forum that you have a lot of experience with these tcus. Are there any affordable tools that can communicate/adjust
    this version or can the software or hardware of the tcu be modified to allow x431 to work with it?

    I don't know of an 'affordable' solution for setting PIS on an early model 360. Mine is a 2000, and could not be accessed with the x431. I upgraded to a CS TCU through Eric, and all was good!

    I can set PIS on the CFC201 of my Maserati with the X431.

    However, PIS does not vary with clutch wear.

    What Kevin said ! Probably cheaper to reflash your TCU to CS spec or late 360 spec, which can be configured with X431, rather than to get a diag tool which can communicate with this generation of TCU.
    I don't know all the diag tools but the cheapest I can think of to communicate with these TCUs are Texa and Autoenginuity. They sell both for $3500 to $4000.

    It's not a matter of TCU H/W (CFC201) but a matter of software.
    Late 360 TCU and early CS TCU, both using CFC201, can be configured with X431.
