Thread: Possible false knock?

Hey everyone! I finally got my **** together and got a bunch of stuff in at once. I pullied down to a 3.5 with the mods in my signature. Car runs great but I do still see knock especially if I'm heatsoaked. The bigger issue is that I see it occasionally build and fall off if I'm accelerating at low RPMS, light throttle even if I'm not in boost. Could this be false KR?

False KR is a bit of a myth.

If the pcm shows you KR, then it sees knock. Mechanical, loose part or predetonation... it's your job to find and fix it.

Most likely it's too small of a pulley for your mods.

I was concerned about that, was contemplating upping the pulley to a 3.6". Its just odd because it can be sporadic and sometimes its worse than others. Thanks for the help. I need longevity out of this setup, as its my DD.

I've seen the torque converters cause this, it's trying to stay locked at a lower speed and that can show as knock.
