Subject: Knock Sensor on Dyno

I am currently building a eddy current dynamometer for testing small engines
up to 70 ft lbs of torque. I am working on the instrumentation now and I was
reading the archive and started thinking about knock sensing. I already have
a digital tach, torque and 10 channel thermocouple thermometer in the works.
I was wondering if I could add a knock sensor to my list also? What
specifically would I need to use a sensor ie power and how do I read it? I'd
like to use a sensor out of the junkyard to keep costs down so any ideas of
which one would suit me the best (partial to GM parts)? Can I put the sensor
in some type of holder then bolt it to the block for testing? Another idea I
have is to read intake air, not sure whether Mass air sensor will work due
to stand off fuel (might make a big flame), or a MAP sensor maybe inside
some type of velocity stack? Thanks in advance for any and all ideas! This
list is a wealth of knowledge, anyone wanting to see my ongoing dyno build
stop by my homepage at http://www.geocities.com/brucepts/pts.htm

            There are those that have, and those that will . . .
