The Megajolt Lite Jr. (MJLJ) is a fully programmable, 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
V4 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)
- Analog auxiliary input to further correct ignition map
- 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/Tuning software Screenshots
- Dual, on-the-fly switchable ignition configuration
- Fine-tune crank sensor position
- Configurable cranking RPM advance
- Load, modify and save Ignition Configuration
- View, log and interact with engine runtime data
- Interactively visualize and tune ignition map
Software Screenshots
Main Screen
The main screen displays runtime data at a glance plus allows editing of the primary ignition map.
Interactive Tuning Window
You can interactively tune the engine while running using the intuitive 3D tuning view.
Advance Correction
The Auxiliary input channel allows for further correction of ignition advance. A typical use is to correct advance based on engine temperature, through the use of a temperature sensor, or react from a 0-5V signal provided by an external system.
Datalogging View
You can observe runtime data plotted against time, as well as save data to a log file for later viewing and analysis.
