Update:
I tuned the lnf last night on E47 = Magical. 0 KR, fuel trims were good. Had to add +6% to the maf due to the mixture being slightly off. I do have a couple of questions.
Tune Setup = 22.5psi tapering to 17.5psi at redline (not holding boost well), 14ish-21* timing up top, PE of .89 under boost.
Tune elevation = 4500ft above sea level
1. I am only seeing air loads of 200-210% falling in to 180ish% by redline, why is that? I did not rescale the load% axis, it's still stock.
2. I setup the DAL for 255max. WGDC table already have 95% in high load areas (stock table), how do I raise boost using the WGDC table? If the max WGDC is 95%, using a value higher than that is useless, right? I've been reading too that people change the proportional gain from .80 to 1 to help out. Not sure.
Thanks for the direction guys. My friend is loving his car. It's so much more responsive on Ethanol.
