False Knock?

My Ultimate knock display is showing that i am getting knock while reving in neutral, only up to 2800rpm. Also cruising at 60, if i give it partial throttle, the knock led will flash. I dont hear any detonation. Today i put in some ur6ix plugs, and it didnt help at all. I have 5 gallons of xylene waiting to go in to be sure, but is it safe the say it is false knock?

What? you mean in the ECM? I have this same issue but I am certain that I have it seated well. I'm running the Ostrich and it must be seated to fit in there. Anyway, if a solution is found please post it. TIA

I had the same prob,false knock at idle and just cruising on the highway with no boost.Turned out to be the chip carrier wasn't seated in the ecm properly.You can't have real knock at idle if everything sounds fine.

Re: False Knock?

My knock is at higher rpm in neutral around 3K. It also appears while driving under accelleration and at shift points. After discussion in another thread and a couple tests we chalked it up to the idea that "built" engines all knock around that range. Xylene didn't affect it at all, it was still there. My problem is that it's causing retard and I'd really like to eliminate this. it's affecting my times and my peace of mind.

Hmm, i have had problems with my chip not seating correctly before, maybe that is the problem. I will check tomorrow. Thanks.

Re: False Knock?

I had the ultimate piggybacked on the stock chip, so now i used an older pitbull chip and piggybacked the ultimate on that, but i am still getting knock while reving in neutral. Any ideas?
