Electronic ignition compatibility

[dynonsupport]

For those of you looking at the Dynon EMS or FlightDEK series and also using electronic ignitions, here's what we know about compatibility with the EMS:

First, what the EMS needs is a pulse that goes from somewhere near ground (within 1V) and goes to or above 10V. This pulse can go quite high, such as 400V-600V like a P-lead does, without damage.

Lightspeed:

Plasma II, II+, III: These will work using pin 6 as the output to the EMS. This is a 10V pulse.

Plasma I: This should also work, assuming you have the tach ouput option. Use pin 13.

Unison:

Lasar: This probably will not work directly. It looks like they have about 4V output. If you are using a Lasar system, let us know and we can probably work out a solution with one transistor for you, or you can use a tachometer sender.

Emag:

E-Mag / P-Mag: This is a 5V output like the Lasar. Will not work directly, but there is a diagram on page 18 of the E-mag manual that shows you how to hook up a few external components and make it work..

Electroair:

Not sure if this will work. We'll need to do some more research, or if someone has hooked one up, please let us know.

For those having the electroair ignition system from Jeffrose, it works very well. I have the RPM indication on my D-180 v4.0. If some one wants more details about the connections to do, I will give him the required details.

Well, that is almost correct. Most of the Lightspeed III units prior to about 2007 only put out a 5v pulse and will not work. Klaus will upgrade your Lightspeed if you send it back in to output a 10v pulse.

That said, Dynon - did you ever get the RPM inputs to accept pulses simultaneously from two sources at different rates of firing (e.g. one Lightspeed and one Mag, where one has a multiple of 1 and the other 2)?

Yes, we've supported different PPR's on the L and R for a few years now.
