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.

• Customize Tach Output Signal
• Monitor/Change/Store your preferred timing shift 
• Ignition Status Reports 

Physical Form – 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.
• Sealed Electronics – Sealed electronics are impervious to water, dirt, and oil.

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.

• Self-Powered 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.
• Starter 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.
• Voltage Reserve – Bus voltage dips sharply when aircraft starter motors are first engaged.  Cold temperatures, low battery charge, and long battery cable runs all compound the problem. E-MAG is designed to endure significant voltage dips.

Enhancements – Making life easier.  E-MAG’s processor supports a number of additional tasks, most of which are aimed at simplifying installation.  An E-MAG should take about two to five hours to install.
