I found some do it yourself instructions for a knock senor alarm. I contacted the person who designed it and they believe it will work on any knock sensor. He also sent me a parts list and some more diagrams via e-mail. If you or any one else needs them just drop me an e-mail and I'll forward them to you.

Their is also a page about a fuel injector duty cycle monitor.

I reviewed the schematics and parts list with a bench tech at my work and he can buildeither of these in about 1hr and the parts should be ~$25 at radio shack.

 

Thanks for the info. I found out MSD makes a Engine Knock Alert. It comes with a knock sensor and a unit that translate the severity of the knock. The unit is about a size of a turbo timer. It will beep and light up a series of LED bar. PN 8964 and goes for $142.95.
