All electronic ignitions
perform a similar basic function. And they all share the same
installation/environmental constraints. So with all they have in common, why
do first-generation ignitions vary so widely in terms of form? The variety reflects
dramatic differences in design priorities (cost, manufacturability, FAA
certification, convenience, etc.). When priorities conflict, designers trade-off
or compromise less important features in favor of more important ones.
This is a common and familiar
practice, but it's based on the premise that "you can't have it all".
E-MAG does not accept this premise, and is stubborn when it comes to compromise.
This is an attitude that's reflected in the number and scope of E-MAG innovations.

series ignitions. [see EICAD]
- E-MAG's most conspicuous features.
Unified Form - All components (position sensor, electronics, and coil)
have been consolidated in a single module that mounts cleanly in the existing magneto port.
Resembling a traditional magneto, it looks "at home" on the engine. (Roughly
3 pounds and 6.25" [Lycoming] or 5.5" [Continental] long with plug wires attached).
Sealed Electronics - Sealed electronics are impervious to water, dirt, and oil.
As an all-digital system, it can hold tighter tolerances through
periods of significant thermal cycling.
Options - Harness are available for both auto and aircraft style plugs.
Safeguards - E-MAG's most important features.
Aircraft engines are different than their
automotive counterparts, and require a highly specialized ignition.
One that not only takes advantage of current ignition technology, but also
includes the requisite engine-specific safeguards.
Model - All
electronic ignitions share one fundamental challenge. How to defend
against the loss of electrical power in-flight. E-MAG
addresses this issue with a built-in miniature three phase brushless alternator. Forget about batteries
or keeping a magneto for back-up.
Now you can run dual electronic ignitions - clean. [see
3 reports of E-MAG "saves"]
Motor Friendly - Like the first rule in medicine - "Do No Harm". E-MAG includes a lockout feature that
guarantees the ignition will not fire before TDC during start-up. Were this to occur, an
expensive starter motor can be damaged or destroyed.

article for more detail.

engaged. Cold temperatures, low battery charge, and long battery

additional tasks, most of which are aimed at simplifying
installation. An E-MAG should take about two to five hours to install.
