Updates:
Seat of the pants, and lack of traction, tells me I'm making improvements in power. It's a warmer day today than two days ago when I last tested, and going WOT at 30 to 40 mph is resulting in tire spin at times now. Feels stonger with less timing actually. Have to be a bit more careful
My changes between two days ago and today:
Made some addl changes to retune the MAF at higher rpms. I think some of my other changes, and/or lower temperatures, are causing the engine to suck more air, because I was hitting MAF/RPM values, I didn't hit before way up high.
EQ Ratio/Lamda is pretty much spot-on now between commanded and actual. Commanded is .845 and actual is between .835 and .855 at WOT w/ PE. I know I gotta get that down at least around .825 for safety.
Dropped ignition timing by a couple degrees. Previous canned tune was 13-17 (scaled) between 4200 and 6400 rpm.
I rescaled that to 13-12.5 across the board in that rpm range. See image. Actually decreasing timing in the upper RPM w/ more boost. Engine seems to like that. Did several runs, and settled here as the best of what I tested.
With spark dialed back and knock retard almost completely gone, I can focus on getting the PE down a little, but kinda sketchy if fuel is going to hold out. I'm around .835 at 5200 rpm up to 6400 at WOT, and low side fuel is dropping to 37 psi at the lowest. High side is staying up over 2,000... so.... ???? Not much I can do until I get LT4 fueling I think?
