Ok so I finally got the ST software and got everything installed. I did some logs today and for some unknown reason I have an occasional knock at idle...not anywhere else in the RPM's, ran it all the way to redline in 4 gears several times and it never knocks....except the occasional one while idling. Any ideas? This was after a reset and new flash of the ECU, but it seems to correspond to an increase in idle speed and increased AF.
really? lol, so your does the same thing? Odd that the wideband goes a bit lean and RPM's rise a bit when it happens though.
I'm going to throw out a guess here that what you're seeing is your a/c compressor cycling (note that you do not need to have the a/c button pushed for this to occur) causing the bump in rpm's and enough noise/jolt to trip the knock sensor.
