Most V-twin motorcycles utilize a single-fire ignition in which each spark plug is fired once for each complete cycle. Other motorcycles (e.g. HD) utilize a double-fire ignition where both spark plugs are fired at the same time.
I'd like to convert a single-fire ignition to double-fire. Why? Just to see if I can do it.
The ignition I'll be using has an Electronic Control Unit (ECU) that provides 12 volts to both coils and also, provides a path to ground to each coil individually.
My idea is to couple each coil's ground pulse to the other coil by using diodes. I have 3 options on how to connect the diodes because I'm not sure that any of the possible methods would be harmful to the ECU.
So, I'm asking if anyone has any knowledge or experience with this kind of idea.
My 3 options are illustrated in the attached drawing.
Thanks,
Jack
