    Id still love to have P10 full flashing, the P12s got it!! Want to run my 02 P10 on an 04-05 OS for more fan parameters. And paying the dealer $75 bucks if it goes wrong both ways doesnt make much sense, Id probably have to buy another PCM and use another license (another 100).

    How close are the 2 OSs , I mean one has SD tuning and the P12 has MAF .
    Would that pose a problem ? Would be interesting to see if it could be done .
    Yeah the OS I am trying to get a hold of is a updated OS that has some trans and other things changed by GM for the better so they say .

    On the P10 you couldn't do that because there is a 2nd CPU in that PCM that does ETC control, we don't program that on the P10 so you would end up with a mismatch.

    Requested P12 file is below.

    They're not close at all, the P10 is a lot like the 99-02 4cyl PCMs vs the P12 is like the E40. I say "like" not exact.

    Bummer, no way to reprogram the ETC CPUs memory? I wonder if an 05 P10 file will run my 02 P10 with the stock wiring...might be time to buy another P10 if I end up keeping it longer than December.

    Yes, but I have no idea how it's done, it's not on the main comms lines, you have to talk to it via the main CPU , a lot of work for a little market, sorry Erik, look forward to the 08 instead
