    That seems conservative enough for me. Just 10psi over stock. Thanks for your help Jim!

    Yeah I wouldn’t go anymore than that otherwise you will get into the realm of getting fractures in the valve body

    Was thinking of something like this to start. Eliminating that flat section so it will downshift with less pedal input.

    Downshift tables for downshift, just make sure it doesn’t overlap into the upshifts or it’ll get weird

    What you see in EFILive and hp tuners for transmission parameters is barely scratching the surface of what’s really in there, would be lost for months if you seen it all lol

    I get it. The amount of hexadecimal addresses Dyno Spectrum mapped on C7 Audi is mind boggling yet they haven't scratched the surface of what the crazy Germans programmed.

    Jim are you an EFI dealer?

    No im not an EFILive dealer, I do sell tuning on occasion and reverse engineer the Cummins/chrysler code and modify the code when I got some spare time, which has been very little spare time for awhile now. Too many other priorities.

    Will see, maybe soon here I can get some more focus back into the coding and start making some progress again towards my ultimate goal with it

    We should talk offline about my needs and if that's something you're willing/able to provide. Shoot me an email to the address above.
