[Diy_efi] Knock Detection using GM ESC Module

[Bruce]

Can you step the resolution up some?.
It's hard to tell but if that's speckling on the center porclean, then your
into some serious detonation.   The Grayishness of the color might also be a
tip off.
If you can more light, and then looking more into the cavity on the side
around the center porclean would help
