annoying knock

I think what i got here is false knock. Seems like I'm getting it in the same rpm range across the entire load range. Let me know if this is real or not. Thanks.

From what I can see, It hardly looks like enough to worry about....

BUT....

It appears to be consistent with the RPM range you've specified.
Try upping the octane and/or reducing timing to see if it goes away.

If it does then you'll know it's real.

If not, then the chances are it's phantom and you'll need to fiddle with the knock tables very slightly.

I can hardly read that, is that saying 3.6 or 36? If it is 36 you can bet your bottom dollar it is false knock, or something isn't right with the engine...

I guess that does look crappy. The highest number on that table is 3.0. Then there are a bunch of 1.0's and a few 2.0's. I also get knock when I rev the engine.
