MSD vs Atp flame total loss????

Yes, the two spark plugs are indeed in parallel.
There is only one coil. It has a primary side and a secondary side.
The secondary side has both plugs connected in parallel, to ground.
That's how the stock Superjet setup works.

multi spark discharge is claimed for having good quick startings and firing wet/fouled plugs. holds a strong idle spark but anything above 3000 rpm, is no longer relevant to multi spark. having a stronger spark is the benifit after 3000rpm.
sorry about that first link, now that you know what you want to buy, here is how to install it and fix it.

they're firing the plugs with less voltage and that was the fix.

huh?
Btw, I'm talking about the stock waste spark system
Take the plug wires off and messure the ohm from ground across plug wire. Where's the ground when using a spark gap checker?
Sweet six cylinder setup.
Now post a diagram for a twin cylinder Superjet.
Did you notice how each individual coil on your diagram serves two spark plugs in parallel?

my laptop tells me post 176 page 9 of 9
You have to realize that the ignition system ramps up voltage until it creates enought volt to jump the spark gap. (I think ignition max voltage ratting is potiential volt).
You have to realize that MSD fires one plug a time (gap .029) and the Waste Spark System(OEM,ATP) fires both plugs together (gap .058). This means that the Waste Spark System needs to make more volts than the MSD to fire the plugs.
So when MSD went to dual channel, it would foul plug because the system made less volts, less heat to plug to burn off un burn fuel at idel and low rpms.
One reason why,IMO ,MSD went with dual channels and dual trigger coil was to offer a feature to retard the rear cylinder because of crank twist.

do you know for a fact that msd made less volts on the multi channel? or is it now just using more energy than is required to simply fire the plug. i think they use more power than required.

haha, my laptop says 6, but it is canadian and my ignore list is huge.
