Well I couldn't be happier right now. Evan swapped my manifold (maybe he'll post pictures of the crack it had) and I finally got around to adjusting my global fuel to bring my LTFT's to zero (well, very close, anyway) and to get the highest cells in my VE table below 100. Car is running great, and for the first time, AFR and Boost estimates are tracking very close to actual values off my WB and MAP.
What I've also come to find, and accept, is that 23psi might be just a bit too much for my setup. Now before I turn the boost down, there's one last thing I wanted to put to the community.
I've noticed in my last pull that as my RPM's go up, my battery voltage goes down. Not a ton, mind you, but it is at 13.9v as I'm putting my foot down, and it slowly works its way down to 13.5v by the time I take my foot off the gas. During this time, I also see the FrontO2 voltage drop at about the same rate (relative). The O2 voltage starts at 0.88v, and by the end of the pull, it's at 0.80v. During this time, i don't see major fluctuations in the AFR's, although a few bounces between 11:1 and 11.3:1 could cause lean knock I suppose... In anycase, seeing this drop doesn't surprise me given what the car is doing, but I am curious how one compensates for it. I'm also curious if this could be the cause of the few counts of knock I'm seeing.
here's a still, link to the log file after the photo. Thanks in advance to anyone that takes a peak. If I end up with less boost, I don't really mind, but if I can leave it alone, well of course that's better.
FrontO2 is the thick, green line, 12v is the thick dotted red line just underneath...
And the log.
