The Interceptor has an analog output to drive our bargraph display, but the signal can also be data logged.

Link to video showing the interceptor working on the bench. I'm playing an old knock tape into it:

Bob Boyer of Random EMS supplied Nize with his equipment. Bob programmed a Vipec ECU to reduce boost when the J&S is retarding from knock. He sent this data log showing the results. The orange trace at the bottom is the bargraph signal, the black trace is boost. I think the time scale is 0.1 seconds per division.
