Default Log with Fine Knock Learn?

https://spreadsheets.google.com/spre...I2ZVE&hl=en_US


Here is my log. This was a 3rd gear pull. I have offer logs and have been seeing about the same fine knock learn around the same rpm range. Is this okay or is there a problem? The map that I am running is a eTune. Thanks

I dont think you should be seeing knock in back to back cells like that during a WOT run. I was told by Cobb that seeing some feedback knock or fine knock learn when mashing the pedal or shifting is normal, and seeing knock correction at WOT could indicate a problem.

Edit: Looking at it again I would say something is up because FKLC goes from -.7 to -5.6 which would indicate several knock events occurring in a row. I would see if you can have a revision done.

You don't want to see that large of a correction (-5.6), especially at high load. I would make sure you don't have anything in the engine bay that is loose/rattling that may be picked up by the knock sensor. Since this is an etune, you should get with your tuner.

Personally I think you are running a little too much timing for a heat soak prone TMIC and are probably a little lean in that area.

For what its worth, I would target a 11.3-11.1 AFR and a 2 degrees less timing than you currently have.

Thank everyone for the replies. I decided to go with a new tuner and now everything is good. Thanks to a eTune from Torqued Performance. The other eTune was a waste of money but a learning experience. However, I do wish that Cobb Tuning was in Tampa, FL.
