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. It 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, configure and save Ignition Configuration
- View, log and interact with engine runtime data
- Interactively visualize and tune ignition map
New with V2.7.x/V3.1.0 beta
- Dual, on-the-fly switchable ignition configuration
- TPS / Load axis calibration
- Improved user outputs with hysteresis
- Configurable cranking RPM advance
