The thought of a hotter longer spark with timing has to improve economy and power. I would like to keep it as simple as possible so I don't think I'd be doing much more than a single mag system. But that is all down the road.

I was a little disappointed in the delivery time. I did have to mail off a flywheel and he had to mill it and install a permanent magnet inside it. He said he had 3 units ahead of mine which is why it took him 2 weeks to make it. If it's a good product, it will be worth the wait. He didn't get it shipped until yesterday.

Because the electronic ignition has longer duration the mag fires during that spark so it has little effect on the combustion cycle. Basically one over laps the other the mag only fires at a specific point while the other has a little advance to improve combustion.

Tried the efii on a 4 cylinder experimental lycoming engine. Highly recommend efii. Install is cake, took an afternoon. Allows more leaning. much smoother motor idle and up top. Instead of popping right away while pulling the mixture, it just sort of starts losing rpm smoothly. On top of that, I have more confidence in the engine since its smoother and I feel safer with 1 mag and 1 efii than 2 old mags.

is this the system you purchased? If so have you run any performance flights - before and after type stuff. Just wondering the value/cost benefit you see. The redundancy factor is huge two different type systems spreads the risk factor.

unfortunately I fill up with a transfer pump from my pickup and don't have a fuel meter at all. I really need to buy one. I just know the motor runs smoother and will probably last longer because of that. Maybe i'll do a few flights with 5 gallon jugs and see what it gets me over the factory chart burn rates.
