    Can anyone post a relatively new GMPP OS?

    Every GMPP crate engine OS I've found so far has been older, and has the 512 g/sec MAF limit and 63 lb/hr injector limit. I know the E67's in the newer cars no longer have those limits...I've got a 2010 ZR1 E67 calibration that's got the same 4000 g/sec and 127 lb/hr limits that my 2010 Camaro SS E38 has. I'm just curious if the newest GMPP controllers have the new higher limits too.

    Nevermind...I think I just found one. Looks like an LSX 454 calibration. Either way, OS 12638778 and the limits are 4000 and 127.

    I think the 8778 is for the erod, though I could be wrong.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    That's cool, I just wanted to make sure the GMPP computers had new enough OS's that I won't need to scale it...doesn't matter if it's from the Erod LS3 or another engine.
