lol dude dont worry. My timing chain rattle registers as knock.

I get a 40-60 back to 0 back up to 40-60 knock at idle.

But beyond that nothing is wrong. 63k mile engine in the car.

That knock sensor picks up more than just knock you have to realize that.

The more you upgrade your car. The louder things are going to get. And soon you'll have a completely inaccurate knock reading, and the car will start to pull timing. I'm on the verge of clipping the knock sensor form the ECU and just leaving it hooked up to the SAFC-2 just to see whats going on, especially at higher rpms.
