You think my part throttle timing looks a little low considering the bigger cam? I am gonna creep the top timing up at 2 degree increments and see what I get.

A bunch of the SSS guys (myself included) combat this KR by bumping up the lockup settings by 5-7mph. That seems to work magic.
Also, this is not real KR. It is noise from the tranny tripping the sensors, so some people will just disable the KR, but I'd rather have the KR protection there in case you do hit a fuel issue or heat or whatever.

I am finding good results with changing the lockup settings. The freaky thing is it is a HUGE burst of knock in the weirdest place at times....one thing for sure, the MAP maxes out when it happens. I'll be cruising at 30%TPS/MAF 21.57lb-min/2880RPM/ and then all of a sudden the MAP goes to 103 and I get 8*kr, spiking in and out for about 2 seconds and then go away. Weird. I don't care so much cuz as far as performance goes, I am not looking for it....just cruising...but would love to know the cause.

I have the exact same thing. Ive noticed that it occurs on Tip in or just when the MAP reaches max. Im waiting for EFIlive to adjust my tables at part throttle.

im looking at a tune i did where my KR jumps from 1.3 to 7.4
i was cruising at 2559 rpms, MAP 12.62, MAF 9.69, 37% TPS, Timing 27.5%
then the spike happens in the next frame at
2543 rpms, MAP 12.62, MAF 9.47, 37% TPS, Timing 20.5%
wtf?

holy crap.
im watching my log... and ive noticed the KR spikes as i watch my tach go up. and it looks like i get a spike evrytime the tranny shifts. and the big spike is when the TC would be locking.
well now that i threw that code my TC doesnt lock anymore and im not getting the same spike anymore.
