Tip in throttle causes lean fuel spike and results in heavy knock
I'm chasing an issue that I can't seem to resolve. I've been messing with the transient fuel table to mitigate most of the issue, but It's mostly guess work. I've seemed to resolve this issue the majority of the time, but I'm still getting heavy knock when I go hard on the throttle, usually enough to cause a downshift. The symptoms show as a lean fuel condition resulting in heavy knock.
E38 ECU, 6.0L with LSA 22% overdriven, 6L90.
I'll attach the log and tune. Issue begins at 10:38:55
