here is another log i took after bumping the timing up some more, i was running pretty conservative on 22* on the dyno. previously i was running 25-26*. I upped it to 23-24* and it felt like it pulled alot more still without any knock. I plan on putting the 100 shot in so im going to leave it at 24*. It was fine at 26* and 75shot so it should be good at 23-24* with the 100. It is pilled really rich, like 10.9-11.2 AFR on the 75 so i only really gain about 40hp from it.
take a look at the log, all looked good to me but id like some more experienced eyes to check it out
Thanks

I always have a hard time analyzing a run without the wideband hooked up (I know I am beginning to sound like a broken record).
But, having said that..overall your Trims look good, and like you said little to no KR. Your narrowbands oscillate a little different than mine (more jagged), but I think they are switching just fine. Perhaps they were a little slower when your ECT was colder, which is probably normal.
If you are happy with your fueling, I think it looks pretty good. Like I said the 'Gold standard' of a log is Actual AFR vs Commanded. I take it you have the wideband mounted, but not connected to EFILive?

Correct i have the wideband running and on a gauge but i have not got that dang usb to serial adapter to program the output so i can log it. I really need to get that done soon.
Comanded afr is 12.34 and i show on the wideband 12.2-12.5 during wot.
thanks for checking it out
