912 CDI (SMD) Failures

these Ignitech modules were installed because Rotax modules failed, often one at a time. The pre-takeoff test failed on one module.

The price of a single Rotax module being three times higher than two Ignitech modules, we mounted Ignitech modules each time as a replacement.

In addition with Ignitech, the assembly is protected from heat and strong vibrations.

I must also say that I am not sponsored by Ignitech (unfortunately!)

We chose this formula because we knew that it works very well, that it is sold with the same connectors as the Ducati Rotax, and that we knew of other machines converted to ignitech modules (6 MCR, 1 Zenair, 1 Eurostar EV 97, 1 skyranger) out of the approximately 50 aircraft that I know of, that's already a lot of breakdowns (2 just in my hangar)

I'm not saying that Rotax doesn't work, I'm saying that we chose Ignitech modules for the price, for perfect operation (some MCRs for 6 years).

we bought asking for the Ducati/Rotax curve

We studied and experimented with the different advance curves to finally program the same thing as at Ducati/Rotax.

(you can program the Ignitech modules yourself) , 

We ain't smarter than anybody, we just looked at our wallets

Ignitech builds a lot of competition bikes, so we thought our Rotax might be good.

The years of experience shows that it's not bad, and for the moment, without any breakdown.

That makes sense, that mirrors what is happening here in the UK. So from your local knowledge it sounds like your failure rate is about 9/50 = 18% and only one of those was a Eurostar.

For Ignitech, I see only one drawback: As the modules are powered by the battery until the Rotax generator takes over, the modules are "armed" as soon as the power is turned on.

If you turn the propeller by hand at this time, it will start.

So be careful to always turn the propeller with the ignition off and checked!

This turns into an advantage because with the starter for an intensional start, it starts immediately.

Moreover, I use Google translate to communicate on the forum, be understanding, otherwise ask Google to do better!!

I have the ignitech boxes on my 912 also because of rotax box problems they work flawless until the other day i was coming from a flyin and all of a sudden my engine started missing turned on the electric fuel pump to see if it would fix the problem but it didn't  was high enough and over a good landing spot so i did a mag check and it started running good on one mag for a few seconds and then started running rough again backfiring and so i switched to the other mag and shut off the other and it start running smooth and did the same thing against i repeated the process for a couple of miles and then flipped on my 12 battery for them and it worked fine.About 5 miles later i was setting up for final plenty  high anticipating a mag failure i turned off the 12 volt switch and it worked flawless to the end of the landing.Ohms at the stator were within range moved the wires around and no movement on ohm meter over or under spec so i am at a loss what is going on any body have some ideas?I checked the wires when running also.
