I personnaly like the Crane HI-4. I've installed about 200 of them on Harleys and Big Dogs and run them in both of my bikes. The only problem is they are no longer available as Crane sold their electronics division (motorcycle) to S&S. At least that's what everyone is telling me. The ONLY experience I've ever personally had with Dyna is sitting on the side of the road with 20 miles on a brand new unit. I've heard great things about the Daytona Twin Tech. It's gaining popularity among the AHDRA folks. Good luck!

Daytona Twin Tec,:flag:
Imo,Ime,same as the Crane was,only better,the best I've found,and super easy install/operation.:2thumbs:
Prolly can get a deal on a bulk buy,with custom curve for the 4",and 4 1/8" bore motors.

I do a fair amount of business with Twin Tec.If we can get enough people interested,I will aproach them for a group price,and custom curve if needed.

Dual plugs??? As in 2 plugs per cylinder? I've not seen a Harley with 2 plugs/cylinder, Honda does it, so do the other metrics.... always thought it would be great to do it on a Harley type motor (ie: BigDog).... am I off here?

Insert title here...
You heard right, I have two plugs per cylinder. The second set was machined into the existing head by a gentleman named Jim Libonati at Megaflo,Megaflow,Harley Davidson, Buell, S&S cylinder head porting and high performance,racing,modifications,flow testing. :2thumbs:
Here's what it looks like...
There's probably 40K or more on this set up and it's never even had a hiccup! :up:

Can-Dog,
I myself have not done this upgrade but have discussed it with several members whose tech advice/opinions I value. All were confident I could get 'r done and mentioned it was an easy job.

Wow....Beautiful scoot 2004BC...triggered alot of memories.I would like to know as well. Sounds like a worthwhile improvement over the stock setup.
I can vouch for the quality of Dyna. I've been running a single fire, dual plug, manual timing adjust, Dyna setup in my 81 Shovel since 1989. At the top of the pic you can just barely see that I mounted the coils up in the tunnel of the gas tank so they're completely hidden and custom cut the lengths of the spark plug wires. I have not touched the timing on this bike in 20 years. Absolutely perfect!!!
Me and my buddy did the dual plug set up on an old Panhead back in the late 70's
2004BC
FREEDOM!!!
Glad to bring back the memories Five Five. 
I'm also running the Dudley lifters which later were marketed by Rivera to straighten out the vale train geometry. Lots of ingenuity was needed to make the antique engineering of shovels and pans perform at any decent level. Relating to the posters topic, I built a couple of shovels with Morris Magneto's which got rid of the nose cone points setups. Electronic ignitions were a big improvement when they came out!!!
Oh yea I almost forgot. I've been running the SU carb on this bike for 20 years and it still SUCKS!!!! but it looks damn good! Classic example of sacrificing performance for looks!
Oh yea again, The Amal carb on my pan was WORSE!!!!!

Those SU's were pretty popular back in the 70's and 80's although as you stated most hated them but they do look good.
Kinda like I hated my ole shovelhead back in the day but they sure are making a comeback now!!!
