We just released a new knock controller for direct ignition, called the Vampire. The system retards only the knocking cylinders, permitting the engine to make more power without sacrificing reliability. Installs without cutting any wires. Control wires simply splice into the coil negative...

J&S is looking for a GN in SoCal to test/evaluate our individual cylinder knock retard ignition. The system interrupts the three signals between the ignition module and the coils. The system taps the stock knock sensor signal, and retards only the cylinders that are knocking. This lets...

Here's something I drew up for the guys on the LS1 forum that are having trouble with false knock: http://www.jandssafeguard.com/test/images/Desensitizer.gif For GN's, replace PCM with ESC.

Craig: I'm working with a Porsche guy using your system. Harv does his tuning. It's trggered from an MSD flying magnet crank trigger, and driving an MSD 7. Am I correct in assuming that the inductive delay in the Global Parameters window is to compensate for the slow turn off of an...

Kenny D. gave me a module a few years ago to play with. He wanted to see if I could "soup it up", to get more spark energy out of it. For reference, I hooked my scope to the module while it was running on his dyno and sketched the relationship of the cam and crank sensor, and the EST signal...
