MegaJolt Lite Jr.

The Megajolt Lite Jr. (MJLJ) is a fully configurable, stand-alone ignition controller designed to control a Ford EDIS 4, 6 or 8 crank-fired ignition module. The result is a precision, digitally controlled distributorless ignition system.

The MJLJ is an ideal ignition solution for carburated engines; it can also work in conjunction with compatible EFI systems.

Features

Current Features

  • 10 x 10 ignition map, with full linear interpolation between values
