Is my knock sensor working??

[RJE 93Green/Tan]

Just bought a datamaster and I made a couple of passes on 93 octane @15lbs of boost. I don't get any knock. I read another post that said to tap on the intake with a hammer. I did that and got no knock. Is there another way to check to see if my knock sensor is working or not?

thanks
Ross

your getting a code 45 o2 rich, you might need to replace your o2 sensor, this could be why it isnt knocking its just running really rich, but I would still maybe replace the knock sensor because I think it should of had some kr at some point there.

the guy that i bought it from made it rich on purpose. when i start it and let it run for a minute the ground under the tailpipe is black.
