Default is this real knock??

98 trans am. has a different cam but idk specs.

The knock seems very random. Sometimes shows knock at WOT sometimes it doesnt. Sometimes shows it down low and sometimes it doesnt.

It doesnt make an audible knock. But i want to get rid of it because it is retarding my timing and i have a nitrous kit just sitting here waiting to be thrown on it.

good long run new gears.hpl

If it's not audible then how are you detecting it?

Gotcha. I had a similar issue and switched to a 160 t-stat and it helped quite a bit

I wish that was my problem. Its allready got a 160 though :/

Im taking it to a local guy to get tuned next week. He is cool guy and he will get running perfect. Just thought u would see if anyone knew how to get rid of knock the correct way without changing the sensor sensitivity

Real knock looks like a sawtooth pattern on the KR pid.

Ok like a consistent saw tooth pattern? Mine just pops up at random times from .5 to 4 degrees.

I cant find any pattern to it at all. Just random.
Did you look at the scan?

Do you know how to get rid of it?

From your log, it seems to me that you are not sufficiently rich where the (sawtoothed shaped) KR occurs at WOT.
