Have been having an on going rattling noise problem, trying to see if my car is detonating but don't know what to look for in this scan I did.
Please someone take a look and let me know what you see.

Did a couple quick scrolls thru it, saw a bunch of idle time.
Is the thermostat stuck open? not much more than 120F coolant temp.
O2s seem to stay below 450mv which account for the really lean fuel trims.
Are the O2 heaters working?

Thermostat is new and have no clue if the O2 heaters are working.
I did notice at wot the KR goes to full, does this mean it's detonating??

I think the best would for you to drop the car with me, very nice! ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
Looked at your last log, there is no knock in the rpm range you hear the noise. The only knock occurring in the log is when you first begin accelerating from a dead stop. The worst is frame #12069, 3* of KR @ 2418 rpm, then you will see 1* of KR @ frame #12071 @ 1795 rpm then it tappers down to 0* by frame #12111 @ 2844 rpm. Then is pretty much the same pattern & always out of the range of your noise. Your tuner can easily fixed this although it is not your problem as described.

I think you are right, this noise seems to be something mechanical rather than detonation.
These screenshots of the KR may help:

I went & had look at the first log after viewing your screen shots. The higher rpm knock was not on the second log. I'm very sure you are hearing the knock as your TPS drops as soon as the the KR appears. You have good ears? ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
So we are back to you dropping the car with me for a while!![Devil](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_devil.gif)
Your first log shows what you are hearing at the RPM you describe....easy tuning fix......are you set up for WB?

If you could get rid of this noise I'd lend you the car to drive no problem.

OK I'm sure it's safe to assume you have not made any tuning changes?
Please post the tune, are you comfortable with making suggested changes to the tune?
I'm guessing the noise you are hearing maybe referred to as "pinging" not detonation as you suggested in your original post.

Spent some time looking at you two logs & your tune. My suggestion just to verify that it is pinging that you are hearing, would be to copy from the Knock Histo in both logs, then Paste Special Subtract to the main timing map.
If that solves the noise you are hearing then you can decide on the more permanent solution.![Nod](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_nod.gif)
My other question is, does it drive properly at lower speeds?
I'm sending you a PM with my email address if you need some help with making the changes I've suggested.

Why copy the whole KR histo and subtract it? That's gonna carry a bunch of garbage with it into the spark map. You have the root of the KR event but then it holds on after the knock and then decays. All of that time after the initial hit shows up in the histogram it's populating, but there was originally only one spot that was the offender...
