    Default CAX service for high Rpm on CMC?

    Yo EFI live!

    Is there anywhere/anyone who provide CAX upgrades for a fee on my file so I can continue tuning as I make hard part changes? I'm looking to get past the 3800RPM hard limiter. I've been researching for a while and it looks like CAX file changes are the only way to get past this. If there are other options please clue me in as I'm hoping to avoid a 5.9 PCM swap.

    Thanks!

    Nick, I actually don't remember where this was at.
    I thought people were able to get past 3,800 with what we had in the software, I say that because either demand for it has dropped off or people are doing something else because it never comes up anymore.
    Need official EFILive help, please go here.
    For tuning support please post your questions on this forum (or other auto forums).
    Sorry if I don't respond to your PM, don't take it personal.

    I did find the thread where you were working with Mitch Cooper and Les(silver bullet) on this and it looked like all the CSP capable tunes were good to go except one Les working on. I figured I was in the same boat and had an odd CSP file that was hitting the 3800 RPM wall. I've researched and came to the assumption that it was cax issue and that is out of my league and time It's a mild truck and I've got full fuel but it hits a limiter like a gasser! Maybe I'm doing something wrong? I'll attach my tune I'm working on now (and a log) that I scaled a few tables (not all) and the limiters are set way high for testing. Hopefully I'm just overlooking something. Any input is appreciated!
    Thanks!
