does any one know what is the normal knoking sensor level in the super afc II in a cavalier 2.4 liters?
First of all you need to set the knock while you are obviously out of boost if you have a turbo and follow the instructions that came with teh safc2. I know theres an idle position and a 3500rpm setpoint i believe you hold the rpms there and then you calibrate it. Whenever the knock level becomes more than that it shows on the afc. Now if you have already done this and you are seeing knock after the fact you either are having misfire troubles or detonation/knock. I would look into your tuning. I think you were talk about the setup but i included both. If your boosted id recommend getting a different tuning device.
Just my 2 cents
