Why I'm I Getting Knock?

We have. Went from 10.9 to 10.2. He said if it still knocked at 10.2 its probably picking up noise, which I hope it is with only 750 miles on the rebuild.

Going from 10.9 to 10.2 is getting richer not leaner. You need to go to 11.4 .

I know that's getting richer , I was stating that I was leaner before I went to 10.2. 11.4 is starting to get lean when fighting knock I think.

Oh ok got ya . But still it wouldn't kill to try it. 11 is just staying on the safe side. I can't see your logs atm but i'll check after work. Is your AFRest lined up with what your gauge is reading? sorry I haven't kept up with your thread.

Pretty much. I'll post newest log when I get home.

I would start with experimenting with slightly richer and see if it changes anything. If that does not work, try lowering/adding timing, It should change, either less knock or more knock. If not, it very well could be phantom knock. I have a similiar issue with knock, to combat it, I am only at 5* of timing up top on 93 on my setup. I am 99% sure it's phantom knock though.

Have you pulled your plugs to verify its knock? I can't see the logs, so where exactly is the knock occurring? If its in the transition from vac to say 2 psi, and around 25% throttle, that's pk. I run a pk ignore in my tune, up to 5 psi. Made daily driving great.
I was getting some times upwards of 15 counts in the above range, and couldn't tune it out. I pulled my spark plugs right after a logging pull, as in, see knock, shut down instantly, and pulled the plugs. If no specks, its phantom knock, and you'll likely see it till you either pull your knock sensor out or you include a phantom knock ignore into your tune.
