Knock Module = small square shaped module that goes into the PCM itself up on the passenger side of the engine bay up near the firewall. Knock Sensor = round sensor that you screw into the bottom area of the block on the passenger side.

Reads what the knock sensor puts out. The LT4 one is better at reading false knocks, which will change the timing, causing SOME performance loss.

And for that, I'm a sad panda.

I only clarified you Sara, since I'm sure he'd ask about what you said

detonation is simply caused by timing and the fuel you have.
