Some issues I've ran into.

[Gravy]

Wideband would shine a whole new light on the issue. I get knock under partial throttle, but my fuel presure is set wrong, i have to adjust way too much for the SAFC compaired to the injectors. Have it set about 4-5psi above stock, and running a 255 on top of it. Figured that out today while watching a movie. Kinda hit me all of a sudden, but without that wideband you don't know what else may be contributing. Maybe your running super lean due to something, or maybe your not.

For an example i got 1 count of knock twice today under partial throttle and with my AF at about 10.0-10.5.
