The EDIS system is a double ended coil designed for lost spark. Like you said, the leading and trailing will be firing at the same time.
When I have everything else shaken down and working, I'll add in the second 4-plug EDIS module. This one is driven off of a separate VR sensor, situated 185 degrees from the first. Leading plugs will fire off the first module. The wire that had been going to the trailing plugs will be grounded. All the energy that was being dropped across two plugs will now be dropped one. Twice the power.
The trailing plugs will be delayed by 5 degrees, but will have the same power as the leading. The trailing will be static (no input from the Megasquirt), and probably driven from a tiny generator mounted in the CAS's slot. Basically, it will be the equivalent of a magneto. A self contained ignition source. Hopefully, it won't require a rebuild at 500hr 8*)
