Single vs. Dual Fire Ignition...
I run the Screamin' Eagle ignition.
I have read tons on this topic, and I have yet to find ANY documented evidence that single fire is any better than dual fire...period. Particularly when it comes to claims of "performance" gains....they are just not there. Nothing.
I've seen with my own eyes a bike on the Dyno, the ignition swapped out to single fire....right back on the Dyno it goes, and guess what.....almost identical curve and numbers, as no two pulls are exactly the same.
Here's what Nightrider has to say about this topic....

To each their own, but until someone, anyone, shows me some documented facts....not just hear say, theory, or their opinion, my thought would be to spend your hard earned money elsewhere if you're looking to increase performance in your machine.....just sayin'

I'm running an Ultima Programmable Ignition with their single fire coil. This ignition module is actually a Dynatec ignition that's been re-branded as an Ultima. Jireh sells these (under the Ultima name) as a complete kit (coil, wires, and all) for $154.00 with free shipping.
It's here:

Here's some comparison photos . . .
The Dynatec . . .
The Ultima . . .
And here's the installation manual that comes with the Ultima:

I've had the Ultima Ignition on my Evo for about six months now and it's been trouble free.
As for single vs. dual fire coils, and purely from a theoretical standpoint, the dual fire produces a wasted spark. And the energy to create that spark has to come from somewhere. If nothing else your coil is working twice as hard for no good reason.
