Seeing some medium load KR

[97AutoXVette]

With the aeroforce installed, I now notice that at medium engine loads (roughly 50% throttle or so), I can see blips of KR up to ~2 or 3 degrees. This goes away to 0*KR then all the way up through shifting as I lay into the throttle more going to WOT. The fact that I get some mid-throttle KR but none at WOT even up past 5500rpm seems a bit odd to me. At first I thought it was false KR due to downshifting perhaps, but now I realize I notice it on occasion just gradually getting into the throttle. Again, the motor is nowhere near building full boost when this KR is seen. I also have poly upper motor mounts (and all the other mods in the sig).

Let me know what you think! Anyone had this particular issue before?

Edit: Note that my AFRs become "enriched" just before I get into any boost so I think we can eliminate an early boost lean condition as a potential root cause

Too rich can cause knock.. try taking some out of the first few time rows in pe vs time vs rpm

Good call. I am definitely on the rich side. I'll take some gruel out of those throttle positions
