I'm having some weird going on. I have a log of a lean area in my WOT pull. I have tons of other pulls that things are fine. Looking at a good log and the bad log the path through the VE table is pretty close. Maybe the cells are different by a percent or two, but not 20% like the wideband error is telling me. My first thought was I have a fuel system issue, but the injector pulse widths are low as well. The other thing that is low is the cylinder air mass. And at some point in each pull things just kind of fix themselves(red arrow in bad pic). I attached two screen shots, one of the good and one of the bad, at the same exact RPM and MAP reading.
The only thing I can think of is that the coolant temp is messing with things somehow. The bad pull is 207 vs 189 in the good. I also don't have my injector tip table set. But in both cases, why would the bad run fix itself half way through? The "fixing" seems to happen at 4200 rpm in several of the pulls.
I ran the car again yesterday and the problem seems to have gone away for the moment, or I did not happen to hit the correct conditions for it to reproduce. Any thoughts or suggestions would be greatly appreciated.
The car is a 2012 Corvette with a stock LS3 and a vortech supercharger. Currently setup to run SD only.
