Real Knock or Phantom Knock?

[caffeinetripp]

I got a recommendation to change the knock sensor's settings a bit; 30% throttle and 2500 RPM. Did that and no more knock. I think it might have been picking up the lifters and the BSE.
Of course, the SMIC doesn't help nor does pump gas. I also upped the fuel as well to hopefully help compensate. But given it was at such a low RPM and only happened after so long a time, I'm thinking it was more than likely the temperatures and the lifters ticking after the oil getting so hot.
Really gotta get that FMIC on. Soon.
