Many have used the EDIS system on fewer cylinders than what was designed for. Example, using an EDIS-4 on a 1 cylinder engine. You'd just leave the coil drive wires disconnected for the unused cylinder pairs.
Hope that helps!

Just got a megajolt E to run my Edis 8 on my V8 - ultimately this engine with go MS3X so the Megajolt will be excess to my needs so I was thinking of putting it in my Haflinger 2 cylinder engine.
I take it from the above comment, I can just use an EDIS 4 module and rig it to only fire half the coil pack - though I do have a 2 cylinder wasted spark coil pack that I could use.
Am I thinking on the right line - I assume the 36 teeth trigger wheel etc is still used.
