Coil f/ single fire
Coil died on my Ultima ignition (Dyna 2ki) yesterday in the rain but came back just long enough to get me in, which was a minor miracle. I think it was a cheap chinese model that came with the kit from Midwest. I've not been able to tell much, if any difference between the single and dual fire setups but I do kinda like this module and now I'm running on my spare OEM stock coil and I'm OK with that except I'm without a spare and trying to decide whether to pickup another stock coil or try a better quality single fire coil.
Any ideas other than stay away from "wild rider" and other obvious junk. Accel, Dyna Tek, stick with stock .. what you all think?

I can pickup 3 OEM coils for the price of one single fire coil of any reputable quality - ain't worth the difference.
Thanks Doug

Ok guys, I guess I will disagree about stock ignitions. My experience with them is not as good. Had many fail and strand me over the years with different bikes.
Right now I wouldn't buy any other system other than a Dynatek. They have been top notch and their customer service is great!
I run their 2Ki on my Fatty w/single fire 3 ohm coils. I had an issue a few years back with which I clearly picked to be the ignition which turned out to be one bad coil. They had me send them the 2 coils to test out and sure enough one of them was bad, guess what, yep, they sent me 2 NEW coils FREE of charge back!
I have also had a Crane System too. Good ignition, priced right.

Learned something new with your post...didn't know you could use a stock dual fire coil with a single fire ignition....The twinkies are single fire, maybe you could use a stock twinkie coil with the ultima/dyna ignition, not sure ...just a thought. Only real benefit of single fire is quicker starts and smoother idle, no performance gain.

I just installed a Daytona Twin Tec ignition on Bertha a month ago. It's switchable between single-fire and dual-fire modes. I used the single-fire mode and their single-fire coil, and I had to run a separate wire from the separate single fire lead on the ignition up to the coil. The Twin Tec can also run in dual-fire mode with a stock dual-fire coil, in which case you don't need to use the separate single-fire lead at all.

Yep, Dyna 2ki and probably most others, you simply flip a switch and use the trigger lead for the rear cylinder connected to the stock type coil for dual fire. That's how I'm wired with a stock coil now. If a single fire coil is used for dual fire, you simply run a jumper acress the 2 primary terminals. The diagrams that come with nose cone mounted modules show all that, and it's quite simple actually.
I do like my 2ki module and that certainly speaks well for their customer service. I may go with a genuine Dyna coil next time. I wondered whether anyone had experience with an Accel. I've heard some negative things about the electrics in other areas lately, but their coils carry a lifetime warranty (?) ...

Being in the Auto Parts/Manu business for a long time, Accel has a great reputation with their parts, I honestly can't say how their bike stuff is...

Rufus,
Gotta Dyna DC6-5 Twin Fire II single fire on mine. It's never missed a beat, but I do carry a new spare on long trips though just in case. Betcha wish we'd had gone together now. Glad you got back in safely bro.
