knock sensor/gauge

The J and S unit is a fantastic knockbox. I have one in my rice burner. It works so well because I have a factory knock sensor. The problem with using it in a motor without a factory sensor is getting the right sensor in the right location to get clean signal. I just order knocksenseMS that has a filter which is frequency tuned for my 318's bore. I plan on just datalogging with it. We'll see if it works. My setup is a 318 magnum with vortech V2 @ 15psi.
