Hi, this is John Pizzuto, aka John at J&S. Mike gave me the ok to come in and tell you about my knock controller, called the Safeguard.
Our first version was released in '91, for engines with a single coil and distributor. Using a single knock sensor, the system retarded only the knocking cylinders. Thousands have been sold.
Dinan Engineering included it as part of their BMW turbo kits in the mid nineties. Jim Bell of Kenne-Bell sold hundreds to his Syclone/typhoon customers, and Corky Bell offered it as an option to his early Miata and Ford turbo kits.
Our latest version is called the Vampire, designed specifically for the DIS Fords, with waste spark or coil on plug ignition.
To install, no wires are cut. The Vampire control wires simply splice into the coil negative wires. To retard, the Vampire simply extends dwell, actually increasing spark energy as a side benefit.
More information can be found on our Vampire page:

The Knock-Finder option will be released next week. The Knock-Finder will show which cylinders are knocking. This should prove useful to those with tuning tools that allow individual cylinder trim. Some tuners retard the back two cylinders a degree or two based on experience. It could also point to an injector not flowing up to par, causing one cylinder to run a little lean.
