[QUOTE="SecondhandSnake, post: 16628115, member: 116684"] I thought MS supported using a second BAP sensor that essentially lets it reference atmospheric pressure and eliminate that sort of issue. I might need to revisit the wiring diagram/features for the PNP version. I was expecting some of the other tradeoffs of MAP vs MAF, like MAF providing for a better driveability with large cams, while MAP is more boost friendly and allows for less restriction. I've got a noisy MAF signal due to MAF placement with my weird compound setup and thought MAP might help in that regard, as well as letting me remove my flow screen. Not to mention that at least with the stock strategy there's all that load tuning with respect to atmospheric pressure (if you use it.) As far as my current tune goes, I've got it well documented, complete with scaling, so I should be able to dump that data into TunerStudio and be damn close. I might even keep it on MAF in the interim. When you say phasing, are you talking basically adjusting an offset between the crank trigger and true cylinder position so that your spark is accurate relative to the true cylinder position? Has it been an appreciable difference between the two? [/QUOTE]
