Intake air leak of exhaust leak will cause high fuel trims and incorrect afr in closed loop if fuel trims are way off then these incorrect rims will be applied in open loop assuming is not a hybrid speed density tune

Thanks. Checked for leaks thoroughly, as I was having other issues with the tune on startup. No leaks. I fixed the startup issue by fixing the "MAF correction after start (neutral)" tables. Only 2 idle modes were screwed up. It would idle fine then "click" to a different idle mode and shoot up to 1700 RPM.

Also, on the datalog I posted, AFR deviates from commanded AFR even when the STFT and LTFT read zero. The car runs very rich (off the chart rich) under WOT.

Playing with MAF scaling is bringing it closer.

I'll have it back on the dyno next weekend for a little tuning session. I can only collect so much data driving around on the street. It's getting better.
