I have another question too, I read that I need to disable the barometric refresh / sensing or something of that nature when I go to the 2 bar sensor. I have noticed the ECU has a separate reading for barometric pressure and MAP, but perhaps it's coming from the same sensor?

i'm not sure I've got that capability to turn off in TunerPro RT. I don't see anything like that in the variables that I have to play with. So if I can't do something with that, am I screwed trying to get to a 2 bar tune with the stock ECU on $DA3?
