LQ4 Tune Question

[YungTyph]

Update for all. Tune is feeling MUCH better now. Disabled the O2s and went full open loop off the wideband, seems much more predictable. With the O2s enabled my long term trims were massively negative, with my wideband still reporting decent AFRs. Fueling and airflow feels pretty good for the most part, just need to continue to cruise and smooth it out.

Another update for the crowd- changed injector data to known LS2 data, and the car drives even nicer. With that change I nudged the VE table a bit (still in closed loop SD) and the tune generally feels amazing.

HOWEVER, when giving it a gradual (although faster than normal) increase in throttle I had the car backfire pretty badly. The wideband went full lean, and i coasted to the side of the road to investigate. Is there any possibility I am actually too rich? At this point I dont even look at the O2 sensors for reference, pretty confident they are junk.

Here is the log showing this event at the end (right before the throttle defaults down to ~17%) Is this just too much throttle for SD? I will dial in the maf soon too, but I want to know its not in my timing or spark or something else.

I have ordered new O2s and will be messing with the PE aspect of the tune, wondering if I just wasn't kicking in nearly soon enough.
