Hi Richard,
If you want to move into the 20th (21st?) century with an electronic ignition system, I recommend you take a good look at the Electro Air electronic ignition. I installed an Electro Air system on the 4 cylinder Lycoming installed in my Comanche and have been very impressed and very happy with the advantages gained from the system.
The most impressive thing to me is how the Electro Air system "restores" power lost when climbing into higher altitudes by advancing the spark timing. This moves the peak internal cylinder pressure nearer the ideal point in crankshaft rotation. That doesn't happen with a magneto. I recently flew my little Comanche across both the Sierra and the Rocky Mountains at 11,500 feet and am sure that the Electro Air system helped. I wasn't very comfortable at those altitudes prior to the installation.
The engine starts easily, and idles smoother now too.
I know the Electro Air system is more expensive than the SureFly system, and that I haven't any experience with the SureFly system, but I know from personal experience that the Electro Air system is able to deliver what they company promises.

Hi Jose. I’m not mad. Just disappointed. Sure fly asked me if I wanted another one. As of today they still don’t know what went wrong. They did find an abnormality in it.
I agree on the electronic reliability of firing a spark plug. I would not like a car with a distributor cap like my 1946 Willy’s.
I’ve been flying since 1980 and have never had a magneto miss in the 4 certified planes I have owned.
I do like the idea. My plane started better. I’m still waiting for a final report. Seems scary they can’t go right to the problem.
I’m not the only one who has had a problem.
Tanks for the wisdom. I’ll continue to swim near the ground.

Richard,

I'm sure sorry you had those issues with your magneto. I would hate to sour anyone off of an electronic ignition so let me share my story.

Jose, I guess this is more for you.

I have a 182P with a PPONK and installed an www.electroair.net/ Electroair certified electronic ignition system (EIS) in place of one of my Slick magnetos.

There is a difference between the Sure Fly and Electroair. While they are both EI systems I can tell you the Electroair has provided me with a noticeable lower fuel burn, better high altitude performance, and MP adjustable timing. I'm not sure I could say it makes me go any faster or not.

I have had two issues with my Electroair. The first is minor. I had an alternator failure in flight and that is not tremendous with an EIS once the battery dies. And of course, on that day my non-EIS mag was running a little rough so I opted to land instead of just turning off the EIS and relying on the mechanical mag. And by the way, the rough mechanical mag turned out to be a loose plug wire from when my former mechanic installed my 500-hour overhauled mag.

Ironically, as I write this my plane is awaiting the arrival of a replacement coil pack for my Electroair. But I purchased my Electroair from SmoothPower smoothpowerllc.com/ which is owned by Darrell Pool. There are not enough kind words to describe Darrell. He is knowledgeable, smart, and stands completely behind the Electroair system. I have learned from experience that Darrell and Smooth Power have my back and I'm not worried one bit that my issue is getting resolved.

Darrell worked closely with my mechanics to help diagnosis the problem I recently developed and he stands behind the product.

I don't want this to come across as a sales post, it's not. Even though I've had this coil pack issue I would not want to remove my EIS system and feel it is a true blessing when it is happy.

Hopefully, the negative experience you had with your Sure Fly won't chase people completely away from an EIS.

Steve

Thanks, Richard.

My factory engine is still new, so I have several hundred hours to go with my magnetos, but I think electronic ignition will be the standard in our aviation engines in the coming years, just as it has been in our cars for 40 or more years.

I have a hangar in a neighborhood of experimentals and almost every one has electronic ignition an loves it. Several of them are flying SureFly units with zero problems, so this is why I was interested in learning the details about yours. Of course, you have plenty of reasons to be mad, but as Don Quixote said: “One swallow does not make a summer”.

Thank you por sharing your experience.

Regards,
Jose

My mechanics set it the way sure fly told him to.
I hope you don’t have one. I’m glad to get rid of it and go back to new magnetos. I was so sorry I didn’t research this more before the purchase. It was a 5 grand screwup.

Richard,
Was your SureFly in fixed or advanced timing mode?
