Any one using Electroair or Surefly ignitions?

A search on the list shows discussions from 2007 on Electroair and of course Surfly is new. Looking for recent experience.

Thanks.

I'm now flying the Surefly ignition. My RV-10 is now set up with one Lightspeed plasma III and one Surefly. I flew the first four years with dual mags. Then about 18 months ago changed one mag to lightspeed. I wanted to use the electro-air system but at the time their crankshaft sensor would not fit on my narrow deck engine because of the metal retaining bracket utilized with the crankshaft seal on this model engine. The light speed system has worked well. Then last fall I removed the last mag and installed the Surefly. I have about 35 hours on this setup now. It works well and I've been surprised by yet a further improvement in economy over the single electronic ignition setup. I did not expect to see a measurable difference. But I had the opportunity to do some long flights. (3 hour legs) to benchmark before and after. This is a trip I've done many times to see my daughter and I definitely have picked up a few knots and dropped a few 1/10 th of a gallon fuel burn for the exact same settings.
I used to see 167-168 knots TAS at 10k and 11.5 gph. (at) 25 LOP. The same loading and oats now yield 170 knots and 11.1 gph. Of course I added one of those TCW back up batteries to the Surefly system to make it not aircraft power dependent. They have done the same to their test airplane.

Do you have data from the original dual mag setup to the Lightspeed only?

Yes. The same conditions with dual mags I always saw 166 knots TAS, 12.5 gph. Same LOP operation. I have flow matched my injection restrictions to within 0.2 gph for all cylinders to go peak.
Other related info.
Engine: IO-540-e4b5 that started life carbureted and I changed to airflow performance fuel injection.
Two blade hartzell BA alum prop with PCU5000 governor.
Everything else about the engine is stock.
Fully finished interior and niceties rounding me out to a portly 1735 empty weight.

Rob;
My hold out is the 15f increase in CHT one gets from the Surefly. I can not afford that increase on takeoffs where I am at 400F normally and higher in the summer.

I'm not seeing any noticeable increase in cht. At high MP the system runs at 25 btdc just like the mags. At cruise running LOP, the chts are fine. Here's a pic in cruise at 11k. If you zoom in on the AFS you can see all CHTs below 324. 172knts TAS, 10.9 gph.

Thanks or the link.
I would be in the same situation.

They certainly does not seem to have a good payback, if you already have a mag. I also think about being stranded on a XC flight and looking for repair or replacement. But itching to spend more $$ on the plane.
