May or may not be the same thing, however, I'm installing a Lyc O-233 non certified engine, and it has a Champion CDI system which comprises a controller and two capacitors which replaces the usual mechanical magneto's. The system was designed, I think, by a company by the name of Lasar, for Champion. You may be able to buy it direct from them.

There's also another company selling an "E-mag" which is essentially the same thing and I know that this is a "bolt on and play" system, at least that's how they market it. These might be worth looking at.

I can't attest to the Champion/Lasar system on my engine ..... because I'm not flying yet. However, I do know that there were some initial issues with reliability earlier on which required a replacement unit, however haven't heard anything since.
