You'll see a lot of things jump during a misfire...

If I remember correctly, EDIS will run on its own fixed to 10deg BTDC, so you can eliminate anything MS control related by disconnecting the SAW wire. Why run EDIS at all when direct fire works, though? It's an antiquated black box with little advantage.
