I'm having some trouble with my fuel trims on 91 with very conservative settings. They easily max to 34% with only 13.5psi of boost. I'm FBO using the 7-24 maps. Any ideas? From what I've tried finding, it seems like some DME's just don't have the same fuel ceiling as others? I just replaced all spark plugs today (NGK 5992, .022 gap) and a coil on cyl1 that was causing a misfire. All is well with regards to that now. Also, is there a way to manually change the scaling for the AFR chart? Its stuck with 2.00 as the highest value for the y-axis, so the values aren't displayed. If you would like to see any other values displayed, just ask.
