The Megajolt2 Family

The Megajolt2/COP/D family represents the next generation ignition controller platform- succeeding the long running Megajolt Lite Jr. + Ford EDIS ignition system combination.

Philosophy
Rather than create one system to fit all applications, a common software architecture will be leveraged across different hardware platforms tailored to match specific usage models. This approach has the following benefits:

Simplified hardware design
Reduced cost and physical size
Minimal to no hardware customization

Timeline
Beta testing is targeted for Summer/Fall 2009 with limited production by end of year.

Megajolt/2

Summary
Megajolt/2 is a Programmable Crank Fired ignition system designed as a single-unit replacement to the MJLJ + EDIS ignition system.

Capabilities

4,6 or 8 cylinders in wasted spark mode
4 cylinders in Coil on Plug mode (using standard coil-on-plug modules)
10K RPM capable
0.1 degree timing resolution

Features

Dual VR Sensor input
- Crank Sensor + Cam Angle Sensor input
4 on-board coil drivers
Soft and hard rev limit
Designed to work with commodity OEM sensors and coil packs
Initial support for 36-1 trigger wheel; other trigger wheel configurations to follow
up to 16x16 ignition map with linear interpolation
- Dual, on the fly switchable ignition map support
4 User defined digital outputs
3 analog input channels
- TPS, Temperature and Aux
- Ignition advance correction for Temperature and Aux
Provision for on-board MAP sensor
On-board expansion for knock sensor module
32 bit 48Mz ARM processor
USB programming interface
