not great for anything. I can't quite wrap my head around how the fueling using the arc2 can work if the maf signal is that hosed, but I am sure there is an explanation.
I keep asking Todd to give me the ARC so I can play with it on my car and figure that out. There was only one car I remember tuning with the arc and actually logging engine load and that was one of my old DR500 stealths. It saw 110load in the peak ranges. I had 660s in that car.
