J&S Knock Controller
 

This past week Chris talked me through an issue I was having with my old, square J&S display, and tried to track down a replacement monitor for me (no longer made, unfortunately). Just want to give a big thumbs-up to a great shop that's kept my old FD running great for all these years.

I can probably repair it but I would have to charge almost as much as a new gauge.

I appreciate the offer, but I was able to cobble it together with electrical tape. I would just unplug the monitor and leave the rest of the J&S system in place and working, but I'd really like the visual warning that it's retarding timing, as a warning that something's wrong with the engine.
