I'm just throwing this idea out there to see if it may have any traction.
For quite a long bit of time, I've been seeing random KR spikes up in the 7s-8* while in boost. I've got plenty of fueling (Wideband isn't hooked up right now, but Narrowbands are in the 930s range). Normally I've never been able to actually hear the knock, but lately I've been driving by a wall on the highway with the window down and I've been able to pick up an audible *tick* sound. No resonant *ping* noise, just a single *tick*, much like you'd hear from a motor cooling down after you stop driving or what you might hear from a spark plug wire arcing. Since this is happening in boost, I'm incline to think that if it isn't real knock, then it could be the spark grounding out somewhere as the cylinder pressures are rather high and making it tough to make the jump.
Is this possible that a grounding spark plug wire could trigger the knock sensors??
3000 miles of driving with daily KR spikes, pulled the plugs and they look like I just pulled them out of the box, brand new...
