Greetings,

I have a 2276 fuel injected turbo charged Bug.

I am contemplating on installing a knock sensor.

Do you think its a vital sensor need to effectively tune the car and maximize performance?

However it can save your motor in the case of a bad tank of gas, assuming your ECU is listening and can retard upon hearing initial signs of knock.

What system will you use. All the aftermarket add on box stuff is just a toy. You need something like the new megasquirt which looks at a window right after TDC for detonation. If you look at the whole cycle you will just hear the valve events since they are far more noisey than the detonation.

valves are a different frequency than detonation, a good system should not confuze them with each other. although a wristpin can be at the same freq.

Your assume that a system that can't even window the actual knock event but will be able to differentiate between knock frequency and valve action frequency is interesting.

Some systems, such as the JS Safeguard, do "window" the knock event. But even without windowing, a bandpass filter is not a complex circuit; heck, it could even be accomplished in analog.
