Still knocking slightly. No IAM drops yet but still getting feedback knock. Tweaked the map a little, scaled the MAF some, knock got better. I think I found the physical location on my log route where I knock. There's a traffic light just before a hill. Zero throttle at light then opening throttle while going up hill. I need to verify that but that looks like what's going on. Knock, just had to type it again. Knockers.
