The whole purpose of this part is to detect knock if it occurs and then will compensate by adding more fuel to the chamber to prevent further knock from happening. Knock can occur due to the fuel not having enough octane. Running 87 octane will decrease your hp but that is all it will do.

What does a knock sensor do? - Yahoo Answers

The motor has to be knocking before it can be detected and the motor pulls back timing. Knocking is bad. Also, the car can only add so much fuel to compensate.
