@Tony1094 here's -55 global fuel, 0 global deadtime, with the injbatteryadj, all as you suggested. It barely runs, if at all, and is super lean. There's no way I'll ever be able to run 0 global deadtime. I went all the way -40 or so global fuel @ 0 deadtime and still runs too lean at idle and light throttle.

Here's where I left it at for now. -48 Global Fuel & 180 Global Deadtime. It seems to like being at 180 for some reason, but coming off throttle it dips below idle and barely catches sometimes, like at 121secs in this log. I gave it a little more injbatteryadj at 12v.
Feeling OK about it, I did a couple WOT pulls here. A little rich under WOT, and then lean at light load cruise. I applied a little parking brake at 140sec to give it some load. To my untrained eye, that looks pretty good.
For the most part I was lean under light cruise and slightly rich under boost. I don't know where that happy-medium would be.
Temps are getting too hot, for me, and the car. So I called it quits here. Let me know if you guys have any suggestions.
