Default Fine knock learn issue.

Hey everyone,

Okay I'm having some issues with stage 2 map trying to diagnosing an issue I'm having.

My j-pipe was hitting the frame and making a serious rattle. This caused some CRAZY feedback knock and fine knock numbers. After fixing the noise and resetting I'm still getting FKL, so far only at about 6000rpm in 3rd gear. I do occasionally see -1.41 feedback knock but I've heard that's kinda normal.

After doing a bunch of research and trying to understand how these calculations work, I was hopping to see the FKL slowly go away until I saw some FBK. I just did 2 pulls and I don't understand why I have no FKL with higher load and I'm getting -4.22 (I was normally seeing about -3.5) on the next pull.

I'm currently trying to do something to make sure it's not the exhaust, because it may still be touching (It gets close when the engine moves from the torque.)

Either way I am getting the new grimmspeed V2 and a pro tune soon, but don't want to blow 'er up before then LOL.

Here are the pulls:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Edit: I forgot to mention I reset the ECU after the exhaust fix.

Edit 2: Looking into my intake Oil Control valves I noticed one it acting wack and also causing an occasional rough idle. I'll try replacing that.
