Electroair ignition

[Steve Ebbers]

I have installed the system that replaces the dual magneto and am having problems with the system on my M20J. I would like to know if anyone has experience with this system and could help me.   Thanks Steve Ebbers  5766Y

I have not done this to my J, but I've been curious, what issues are you having?

There are a number of posts on this topic already as well btw, Google search may be better than the forums search, one example

Also watching closely and interested to know more.

What are your issues? Did you do it yourself, or a shop? First time installation?

+1 here. 

I would love the improved fuel consumption and cleaner burn (higher spark voltage) of the EIS. 

However, Electroair's website is kind of unclear about the single-drive dual Bendix magneto replacement. Although their engine AML says that Lycoming IO-360-A3B6D is an approved model, it lists the EIS 41000 as the installation model. However, their website shows the EIS-42000DM as the "correct" model ("The EIS-42000D Electronic Ignition Kit is a fully STC'd kit to replace the Bendix single drive, dual magneto with a complete, DUAL ELECTRONIC ignition.")

Other things that caught my attention: all 41000 models have links to AML, installation instructions, AFM Supplement, etc. The 42000 does not. Their STC page does not show the 42000 anywhere. I contacted their distribution partner in Brazil and they said that their STC for the Bendix dual mag is not yet validated by ANAC (Brazilian civil aviation authority), but I am thinking that their FAA STC hasn't yet gone through for that specific model... or am I missing something here?

Their solution for the -A3B6D is a bit muddy, but fully approved and complete.  The STC package is essentially TWO EIS-41000 kits, plus the backup battery kit from TCW with a wiring schematic to integrate everything together.  Each EIS-41000 kit is installed separately since they are truly independent/redundant.  They do not have a separate installation manual for the -42000 kit.

What’s the benefit to that system? Is there much of a performance gain to be had with some sort of adjustable timing?

I got significant performance.  2ish gph fuel savings for same power output. No overhauls not life limited. Better at altitude

What I'm most interested in is that at my first and most recent annual the shop said the bottom bracket for my dual mag was missing and the top one wasn't on that well either -- they said it likely wasn't torqued right. On the day I took off to take it to the shop it was 500ft overcast, which is lower than I normally take off with, idk what it would have been like if I lost my engine. I want more redundancy.

I just helped do an annual on a J model that has the system and it is a disaster. The engine starts and runs but in cruise there is something horribly wrong. It was supposed to have been professionally installed but it requires 14.1 gallons an hour of fuel flow to keep the cylinder head temp below 475. The spark plugs get completely loaded up with lead. If your engine is running good with the magneto do not try to fix it. Checking the timing is a challenge. My neighbor had to check it on his airplane with a strobe light while the engine was running. On my neighbors plane the spark trigger that plugs in where the mag was had a manufacturing defect that they failed to detect during the three times he sent it in. It would be nice to hear Justin’s story to see how he got a good installation. They also want you to send in your mag or pay 1k. Why would an electronic ignition manufacturer need your old Mag? Obviously I am not a big fan. Good luck If you decide to install it.
