Anybody?

There's generally two ways to help knock - add fuel or reduce timing. It would help to know what the AFR is when the knock happened. AFR from a wideband would be ideal, but AFR from the stock sensor would be better than nothing.

 

Or you could just pull a degree or two from the RPM/Load points where it's knocking.

Ok pulled 2 degrees average across the knocking rpm/load from KCA maxA table.Why isn't my boost where it suppose to be(14.7) and why doesn't the FBKC change under WOT since i'm knocking.

Anyone again?

There are RPM and Load ranges where the different knock strategies are enabled (FLKC, FBKC, IAM). If you're in a range where FLKC is enabled, the ECU will use that instead of FBKC. Unless load is changing rapidly, in which case it will prefer FBKC.

Dunno about the boost problem. If IAM drops low enough, boost will be cut. Or you might have a boost leak. Were you at 100% throttle when you saw the low boost?

Does this log for boost look good except for the lower IAM due to knock.
