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? |

ok....about knock is normal that you don't read nothing on the channel monitor, cause it says just when the knock goes over the values you set in Settings->Knk set menu. there you have to insert a value for idle and one at about 3k RPMs.
Anyway....in sensor check display you read the actual knocking value. Tell me this: you said that at idle your knk is about 20....mine too when the engine is cold.... Can you say me your idle knocking value after at least 30 minutes of engine run? Thx Edoardo
