I'm making some assumptions here.
So if that's true could I use EDIS on a 2 cylinder 2 stroke with EDIS #1 coil firing #1 and coil #2 firing 2?
Yes, but you also need to make sure you are grounding the other side of the coil. I'm not sure how it would like to be firmly grounded vs. going through a second spark plug. Then again, the spark w/o charge isn't much resistance...
The other thing you could do is get an EDIS controller and drive a single COP for each cyl with it. The EDIS controller is separate from the coil pack.
Alfadrivers suggestion of COP is what I was gonna say.
That would get you running in "limp mode" IE a fixed 10 deg BTDC (or actually whatever you want as a fixed number, you would just set your trigger wheel where you needed it). To get any advance out of the system you would need a megajolt or megasquirt ecu to control it.
Thanks guys, yes I should have been more clear that I meant the controller running something else. This would be an application where a set advance is fine. Maybe an ignition cut out to get it spinning then turn on the ignition.
In reply to Stampie (FS) :
I thought there was an MS product that did control of an EDIS system. It needs a very simple input.
Yes, you probably could. But, before you turn the pistons into several molten piles of slag, it's worth noting that the ignition advance on two strokes is opposite that of four strokes. I.e. 2Ts will often start around 30° btdc just off idle, and end up at 12-15° or so btdc at peak power.

That pattern is the same for 4 stroke engines. Ignoring idle spark, low loads have lots of advance, and high loads have less.
The whole "advance from idle" thing is more a result of mechanical advance.
And modern idle spark that is very retarded is a matter of engine speed control (which is a whole lot faster than adjusting air)

Ok so this is an interesting discussion. The way I read that is the limp mode might be around dead on. Would there be a problem with being less advanced at idle?
