So I'm kind of concerned that my engine is knocking. I just installed an s-afc and I've been monitoring knock, and have gotten numbers as high as 100 on it. It's not a consistant knock, and I can't hear anything, but it sometimes happens when I take my foot off the throttle and when the car shifts.
All I have is an Intake, Exhaust, and Underdrive pulley. I'm not leaning out the engine and I still get the knock numbers when I increase the air/fuel mixture by 10% throughout the band. I've calibrated the thing 3 times, anybody know what is up? |

My 2cents worth here!
http://www.apexi.com Check for documentation. Knocking is normal guys. You cannot stop it, but you can minimise it. Once you have the correct a/f ratio and stock timing and tuning, then take your values from there. One thing that you need to get straight is the figure over a period of time. That is, it it calculated for per min? If so, those values seems quite normal. The thing is, get a base like (except edo since he have 12+:1 compression) with stock settings. -------------------- West_Minist
