The Next Generation

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.  

EICADTM  Expanded Controls - E-MAG Interactive Control And Display is an optional set of ignition control capabilities built into our newest series ignitions. [see EICAD

  • 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.  (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. 

  • Harness 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.  

  • 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 self-powered model, the "P" model.  The P model draws power from the aircraft buss, but is backed up by a built-in 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 P-MAG "saves"]

  • 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.  - See Sky-Tec's kick-back warranty extension (exclusive to E-MAG), or their "tech-talk"  article for more detail.

  • 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 three hours to install.  

  • Quick-Set TM will let you set timing for one or both ignitions in about 60 seconds - without the need for any special tools. 

  • No need to install satellite electronics cases, coils, or pick-up sensors to the engine - just the E-MAG and harness.     

  • Digital tach output.  

  • You can reuse your existing keyed (or other) kill switch to control E-MAG operation.  

  • Our newest 114 series works on 12 and 24 volt systems.

Note on battery chargers:  Some styles of ground (110 volt) chargers will hammer the battery with pulses as part of their normal charge cycle.  Such hammering is not a typical buss state and can cause problems for the ignition if it is powered ON during such a charge.  KEEP IGNITIONS POWERED OFF WHILE (GROUND) CHARGING.
