What is the difference between a single fire and a dual fire coil?
What are the benefits? Dual fire ignition systems fire both spark plugs from a single coil at the same time. Single fire ignitions separate the firing pulses, only firing the cylinder under compression. The main advantage of dual fire systems is simplicity and low cost.
What is a single fire ignition?
A single fire ignition eliminates the backfire problem and enhances idle quality. The single fire ignition uses separate coil windings and electronics to fire each spark plug independently. Spark firing occurs only on the compression stroke.
What’s the difference between dual fire and single fire?
The only practical difference between the two is that a single fire unit needs to know which coil to fire – front or rear, while a dual fire system just fires its single coil at an interval given by the pick-up (adjusted in your ignition unit for the 315/405 deg difference between front and rear).

Using a cam sensor would be the most reliable way to phase a single fire ignition to a crank. Hoople is absolutely correct in his points about the stock dual fire (or wasted spark). Now he’s got a TC, but at least on a carbed Evo the conversion to single fire is easy:
The only practical difference between the two is that a single fire unit needs to know which coil to fire – front or rear, while a dual fire system just fires its single coil at an interval given by the pick-up (adjusted in your ignition unit for the 315/405 deg difference between front and rear).
