Picking up Knock--Log Included
 
1 Attachment(s)
I have noticed my AFR have leaned out from my original targeted values at the upper RPM range. Right after flashing I was hitting my target of 10.8, but now a 5-6K miles later I am hitting 11.1-11.4 at redline. At the time of when I was road tuning I had no knock. Now with the leaner AFR I have noticed some knock between 5400-6500+ RPM.

Why is this happening?

I have attached a .CSV log file renamed to .DOC. Please rename to .CSV and view with Excel.

Doesn't look to bad to me. What is your learn view doing?

I have not looked at the learned view. Don't I have to have a before and after to really get anything out of it? I can pull it if it will tell me something.

It just concerns me that my AFR targets are no longer being met and now I am picking up knock. Is it normal for the ECU to lean out the targets?
