Supercharged 2013 Jeep SRT8 MAP limit?

[UMSTuning]

Is there a hard coded limit we cant go past on these cars? I seem to be hitting a cut right at 200kpa.

hello, good evening no amgio you have map reading limiters The map is limiting you to more PSI check those maps

You really, really need to stop doing that, my friend.

It's been my experience that the Dodge GPEC2 ECU doesn't read boost about 14 psi (roughly 200 kpa). so you have to do some scaling trickery. I haven't completely figured it out yet, but I'm working with someone to get it ironed out.

Go to :
ENGINE DIAG-------------AIRFLOW--------------------MAXMAP(45635)---------------set to 195kpa
this will prevent the map to read higher than 200kpa and will avoid the limiter.

how much boost you shooting for? you should be ok at 15-17 psi fueling wise, more than that and probably you will have to scale the map sensor the old way or something like that.
