    To see the full flash option you have to be plugged into the OBDII port.

    Its the same procedure as flashing a DSPx OS into a Dmax. Plug your V2 into the laptop first, then open the tune tool and press the BIG RED arrow.

    Gil, I downloaded that file as well and have it saved on my laptop. Better economy huh? Might have to go through both files and see what the changes are.

    Ah gotcha, Ive messed with TC settings a lot on my P10 and if nothing else it locks up firmer (almost another shift) and locks/unlocks quicker when it should.

    Just make sure it is a full flash or else you will not get the correct changes.

    EFILive wont let you cal flash that OS, it will throw an error message saying the OSs are different and reset the PCM. Good thing, otherwise people could mistakenly flash a cal in that doesnt match the OS! That would be horrible.

    Erik , he was talking of running a script , just wanted to make sure he didn't make a script off the 7882 and run it on a 440 then cal flash it , but I don't think that would work either , never tried .
    Yep different OS will not allow cal flashes.

    You cant script other OSs because you cant compare them, however you can run a script on a different OS than it was created on. For example, I have a script for P10 tuning that I built using my 02 file as a base and have run the script on many 03/04/05 P10s.
