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?

I FINALLY got this prick in, with dodgey soldering and all.
I followed the T5-C diagram but I don't get a knock reading at all. I get knock readings on the "SENSOR CHECK" under "ETC" of about 20 when just ideling. I double checked my wiring to see if I connected the knocck wire to the correct pinout and its correct.

Have I hooked it up wrong? How can the SAFC get a knock reading on the sensor check and not read any knock on a Channel 1 under "KNOCK"?

Thanks everyone for helping me out. I am probably going to book some dyno time in to get it tuned properly.
