i just picked it up and the great news is that it does indeed have the improvements of 4000 g/sec MAF table, expanded fuel injector limits to 16 g/sec, etc...
So this should be a great controller now for stand alone FI applications without needing scaling, etc... my '85 IROC with the previous LS376 controller was hitting the 512 MAF limit, etc with only 5 lbs on the maggie (566 rwhp on mustang dyno)
So a couple of questions if anyone knows-
1. Anyway to tell what 90mm throttle body this is programmed for. The previous GMPP OS was for the older 90mm
2. Is there a way to write this OS to a "standard" E67 controller vs having to buy it programmed from GM... ie could it be written to a LS9 vette loaded one, etc... Right now to the best of my knowledge you cant get the Tech 2 to program GMPP OS and have to buy it special load
So know i have some updating to do to plug it into my IROC, but this looks like a good base controller
Thanks
