Here's the logs. It seems to happen around 1/3 throttle and 1.3+ load. knock under full throttle doesn't go over 3 so... we'll se what Torrie says after I send him the logs.
Do you hear any audible knock when the +KR readings manifest?
Personally, I wouldn't give the KR reading in your rev1knock log a second thought; it's pretty benign. The big spike and long ramp down to zero on the rev2knock log is interesting, but not necessarily concerning.
I may very well be wrong, but I was under the impression that KR is fairly normal under partial throttle, since the ECU is trying to maximize fuel efficiency. All your fueling (lambse) looks lean, too, which I believe is also normal under partial throttle.
It would be interesting to see, if you can get into a high KR state like the first one in your rev2knock log, nail the throttle and go WOT (assuming it's safe to do so), and see if your KR comes back down. You should also see lambse drop down to around 0.8 or so as the fuel mixture richens. If KR drops quickly under WOT, then I'd guess that those spikes you're seeing under partial throttle is probably the computer adjusting for fuel efficiency.
