Hi Paul,

I think that I should install a knock sensor on my 13b since it is turbocharged.

Anyone having info on this would be greatly appreciated.  Where is it available?

I would prefer a unit that display the information with LEDs instead of sound.

Thanks

Rino

That's a problem as sound is, I think, the best way to do it.
The human brain is an excellent real time audio signal processor. 
Witness the problems computers have in recognizing speech patterns.
My idea is use an audio amplifier hooked up to the knock sensor.
Not as quick as a computer in retarding the ignition however.

Rumor has it that once it knocks it is too late to save the apex seals.

Knock is a very strong function of intake air temperature.
The very best you can do is install an air temperature
sensor in the intake manifold and never let it get over
130 degrees F. That is why I am working on squeezing in an extra
large intercooler.
