I applaud the thinking here. Everyone likes to review anecdotal data-My brother's friend's co-worker.........I saw a car on the side of the road... But did you notice the 10,000 that drove by that day that functioned perfectly? When you look at the actual failure rate given the millions of vehicles on the road today, there I am guessing that the evidence would support the inherent reliability of an electronic ignition.
It has been pointed out that there are structural differences between auto conversions and purpose designed aircraft engines. I liked the previous posts that required you develop a mission statement. Define the purpose of your project, and design and develop components around that purpose. That will maximize your efforts, safety and ultimate utility.

Well all of the shops I have talk to about magneto (since I am always doing business with them for my customers) say 10 out of every 65 mags they send out rebuilt get returned in 2 to 3 years due to failure..........yet I have had 3 cars all with electronic ignition and each one with over 100,000 miles that are sitting outside right now just like millions of other people who have never every had anything done to the ignition or fuel injection system except changing the spark plugs and wires.

Good engineering logic and purpose. This is one for the achieves.
