I changed the transient pulse and short pulse threshold. Rest is the same. Try that and see what it does.

That did it!!! I've been struggling with this for the last 6 months! You guys don't even know my excitement levels right now!

Common problem with big injectors with large offsets, glad you got it sorted.
I had a mate call with a strange issue 2 days ago where idle fuelling was fine, but put any throttle into it and it would peg rich no matter what changes were done to VE etc. In this instance it was the stock default minimum pulse width settings causing the issue. Once my car is repaired (cam and lifter failure) I will be doing some more testing to see if I can replicate his issue and update my earlier findings on IBPW composition.

I really appreciate the help! On my brothers car, while idling in open loop with commanded AFR at 14.6, it was roughly 12-13 on the wideband, I could go into DVT's on the scan tool and command 20.0 AFR and the wideband wouldn't budge. Now it idles at 17 afr on the wide band when commanded afr is 14.6, if I command anything leaner with the DVT's it responds great, if I slide it to far over it'll die. So it's finally working! Now I've gotta build the VE! Yehaw lol
