I have made a few wot blast and scanmaster has never shown any knock retard. I know that is a good thing but it also has me wondering is the knock sensor operating correctly. I'm running 18psi of boost with alky. Base fuel pressure is 42 with vac line off.

Does anyone have a picture of the knock sensor and its location and a sure fire test procedure that will set off KR on the scanmaster?? Tried search option to no avail

It's located behind intake manifold and has a single wire going to it. It's a round thing, you should see it back there. I'm not sure how to test it

Tap the back of the block, gently, with a handle of a hammer or screwdriver while key is on and you should see kr on a scanmaster. If not, try again, gently, but use the hard end of the hammer, if no knock, then something is wrong with the sensor or the circuit.
 
18 PSI and alky should easily show zero knock. Some people can run 18psi on 93 octane alone!
