2) change ZKLAMFAW to "100" FFFF. This is very important. Without this, the lambda requests are filtered through time filter and new requested lambda takes time to take effect, as much as 1-2s. If you leave it in stock form, the KR fueling has no chance to work properly as the requested AFRs are severely delayed and you'll be spiraling into more and more knock unless you put low AFRs into table... but that's going to biet you when in different gears/longer pulls. With it being FFFF, it is an instant change. No longer nice and flat AFR curve though, the ECU really starts to work on proper fueling with this in.
I have not changed this and have never noticed a fueling delay with kr corrections or fueling in general. I also do not remember ever covering this before. I was under the impression it would possibly delay LAMFA (driver input) switch over, but even then I have never experienced it.
I am going to max it this evening and see what changes.
