Electroair Electronic Ignition

[TNIndy]

Has anyone installed an Electroair system on an F-Model. I'm curious which mag should be changed? I have a 67F model, Continental S4LSC-200 left Mag, Continental S4LSC-204 right mag

Dozens of good pireps on SureFlys around here…

Replete with install challenge solutions for the few that have arisen…

 

There may be an electro-air install with some interesting details around it….

If you haven't bought the Electroair, get the Surefly.

Have had both, never liked the Electroair, replaced it with Surefly.

The Surefly will do the same as the Electroair, at substantially less initial cost, and with less hassles down the road. With the Surefly, you will also use the same spark plugs in all positions, so you can rotate them and get maximum life.

Not sure why that would be? Electroair is good with the plugs I have

For optimum results, they prefer that you use their wide gapped plugs, which cannot be used with the magneto. If you keep all gaps the same, then you can rotate them every 100 hours to equalize the electrode wear.

Got it, Thanks!

Consider this when deciding whether to go electronic, and which one to buy. These are my observations:

Pretty good write up!  I’ve had a SF for about 2 years.  I live in Washington, so 9500-11500’ are normal cruise altitudes.  I did see a couple of knots improvement when slightly LOP in cruise at those altitudes, maybe 2-3ktas.  I have pretty extensive data before and after.  As you said, below about 7000’ theres no difference from a mag.  Also, ROP it’s pretty hard to tease out any gain, even at higher altitudes.

I will say that if the SF is mx free for the life of the engine, there may be some cost savings from labor and 500 hour mag inspections.

Thanks for providing the write up.
