Yep i agree. Right now im at a loss to how to get the knock level working again. Where should i start?


Edit: looks like my tuner accidentally cut that wire

accidentally LOL.

Peak timing for sr20det engines is 9* with 14-18 psi on 93, and it looks like many if not most of the "tuners" out there think it is 15* for some reason, which results with high knock counts on the street (but apparently not on their dyno)

Anything over 60 knock on pfc is bad on pumpgas.
I have yet ton go over 50 knock on e85 though lol.
The powerfc has a default where it flashes the cel when it knocks over 60.
It can be changed but only with the software +cable
