Surefly Electonic Ignition

[FlyingVAce]

Does anyone have experience with these mag replacements to an all electronic version?

.............. forgot to ask if anyone has installed ANY of the electonic mag companies out there? Not just the SureFly, ie. Electroair

Yes, we have lots of threads on this.  I’ve had a Surefly for ~4 years on an io-360.  We have people with them on turbos and even someone that has two.  Whatvtype of engine do you have?  What would you like to know?

Here’s a really old thread :

I installed one in a 182.    It worked fine.  The engine (Continental O-470L ) started a bit easier with that mag.    Not enough performance difference to be noticeable.   It did show slightly better fuel usage (either reduced fuel burn or increased speed) but it was such a small amount I could only tell through careful measurement.   Although I could run a little leaner at low power settings (wide open throttle above 10,000 MSL) where it wouldn't run smoothly before.

I could tell which one was which when doing the mag checks both on the ground and in the air.   Turning off the regular mag did next to nothing, a slight rise in EGT.  Turning off the electronic ignition had a much bigger effect.

Mine has SureFly on the left mag. No issues so far. Starts are really quick…

plenty of info regarding Surefly available with search.  Would suggest google search "Surefly site:mooneyspace.com"

In general, I have read mostly good experiences with Surefly.  Most benefit felt to be with single electronic "mag".  Set timing that doesn't drift, ability to advance timing with low MP for normally aspirated engines, smoother LOP if you can fly LOP, easier starts due to immediate spark, 2400 hr TBO so no need for 500hr IRAN.  Given you are paying equivalent cost for new mag you should time it ideally with needing to replace a mag or when you come up on IRAN time.

Anecdotally I've read more difficulties with Electroair vs Surefly.  I have a Surefly on my M20K and have about 200 hrs on it; fixed timing, smoother and deeper LOP, easy hot starts (but this wasn't that difficult before, but a little quicker/easier after), no complaints.

Early Surefly had issues with too low of voltage spike set point/regulation which required capacitor addition.  This was fixed by about revision C.  Also early Surefly had longer reset time when you turned it off; so on mag checks at runup there would be a stumble or hesitation.  This has been fixed with quicker restart time.  My runups are very similar for both mag and surefly.  Pax probably doesn't realize a difference.

That for today is great info and I'll look at the older threads....... thanks to all.

Love mine! 

Replaced it recently when a mag went bad and was a great decision. Install is straight forward, starting is much easier.
