Tuning KR in cyl 4 only
Hi all. I have been reading alot about KR and the LNF's. It seems they're stupidly sensitive and lots report false KR when under virtually no load.
I tend to get bursts on cyl 4 only and it's mostly around 2k rpm's when I roll onto the throttle.
Being that it's cylinder 4 only and at such low rpm/load I am going to assume this is false.
In your experience has re clocking the rear knock sensor helped this at all?
I took a look and cannot see it under the intake especially with that foam sound deadener in the way.
Here's a couple logs if anyone cars to take a peek at them.
Thanks in advance!
Look ~3:17 for the kr.

That is tip-in KR and its almost always false. Also, the ECU likes to pull timing/utilizes a cylinder deactivation strategy if it catches wind of a mouse fart.
Watch to see if your commanded vs actual changes during a KR event. Best way to determine if it's real in this type of scenario. Also, make sure fueling is in line.
