Knock sensor Options

[terrymason]

I've got another thread going where I'm trying to set the mixture on my dual dells, but this got me thinking about a knock sensor. Does anyone here have one? I see there are some aftermarket ones like these:

Is there a cheaper alternative?

BTW - I tried the search, and kept getting 1000+ hits.

Knock is usually used by the engine management computer to retard ignition and to deal with poor quality gas or gas of a lower grade than intended. There's not a whole lot of point if you don't have an engine managment computer.

There is a megasquirt knock circuit available which basically turns a light on - that's what I have in my car although mine is actually hooked up to the megasquirt.

There may be other issues though - Knock sensors are basically microphones, and I don't know that they are thermally resistant enough to sit where they would need to be (probably on the cylinder body for a TIV) - plus mounting would mess with the cooling some.

I'd get a WBO2 first if I were you.... it will give you more actionable information.
