Okay, who can engineer an ignition system for me?

Is there already a trigger wheel and pickup on the e-shaft?   

    What system are you using?     
       

    Gross timing should be about 25 degrees  leading/trailing spread about 6 degrees.   

      Setting up a crank trigger ignition on a rotary is tough.

I haven't looked very deeply into the MSD solution (we run the stock dizzy and ignitors), but I'm curious how it would work if there's no e-shaft angle sensor.  The 12A normally uses the pickups in the dizzy to tell the igniters to fire. 

If the dizzy holes are welded over, they MUST have had some other way to trigger the plugs, maybe a later model angle sensor or something.   If you have that, you can run the MSD option.  If not, like Erik stated, you could re-isntall both dizzys and their associated ignitors and coils, which I think would be the simplest way (especially if you can find the parts for cheap).  If both motors are in-phase (both #1 rotors hitting TDC at the same time) you could probably just use one of the dizzys to trigger the ignitors, but you'd need both for spark distribution.  If they're out of phase, you might be able to get away with the same setup (just swap #1 and #2 leads if they're 180 degrees out of phase), but for simplicity's sake maybe use both independently for both triggering and spark.

Basically, unless you go with a fully aftermarket ignition, I think you would need two full systems (2 dizzys, 4 igniters, 4 coils, plugs wires, etc.).  But this is my first rotary car so I could be way off base; I'm sure the pros will correct me...

I'm the one you need to talk to on this project, I can do any rotary ignition

Send me a email to c2rotart at gmail dot com

I need some pictures of the setup and I will help another rotary brother.

Alex, I won't be there (I work 6am to midnight), but you can feel free to go try it. We gotta figure out if they are phased, and how. I'm guessing compression tests?

From the previous static-advance ignition system, I'd guesstimate that they're phased 90 degrees. As in, a spark every 90 degrees of the shaft revolution makes it run (if it ran on all four).

Do you work Thursday or Friday? I'll be far far away Friday but I can send Tolik with instructions and pre-cut, pre-wired everything. Thursday I have an open evening.

I know it isn't the best but for simplicity, run both engines the same

Rotor 1 and rotor 3
Rotor 2 and rotor 4

I knew the now deceased builder. I inherited some of his tools and stuff. I may have a wiring diagram. Just recently found out the car was sold and just found this website. Any way to contact speedycop in person?
