Powerlogger file review. Is the car too rich? False knock? Any help greatly appreciated!!

I have been dealing with a knock problem and read all I can about what causes knock. Here is a file of a run to review. Any assistance would be greatly appreciated! Mods are in sig.

What wideband? What chip?

Aem wideband and a tt chip set for e85 and 60 lb injectors.

That does look way rich. Big knock looks false. I would back the timing off though. Go back to like 18 degrees timing and see if the knock goes away. If it does you can start leaning it out. Good luck.
