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
  • Load axis calibrated by on-board Manifold Pressure (MAP) sensor or external Throttle Position Sensor (TPS)
  • Four user-defined output switches, which trigger on RPM or load
  • 'Shift light' output- for driving a dash-mounted shift light
  • External Rev-Limit trigger output (The Ford EDIS module has no 'rev limit' signal, so an external circuit to disable the ignition coil is required)
  • Modern, easy to use, and customizable Windows-based configuration software
    • Load, modify and save Ignition Configuration
    • View, log and interact with engine runtime data
    • Interactively visualize and tune ignition map

New with V2.8.x/V3.2.0

  • Dual, on-the-fly switchable ignition configuration
  • TPS / Load axis calibration
  • Improved user outputs with hysteresis
  • Configurable cranking RPM advance
