Product Description

E-Magneto Complete Single Ignition Kits

EMK00301 and EMK00801 E-MAG Ignition Bundles
Complete ignition kits include the E-MAG module with the harness, incidental hardware, and adapter set needed for a full installation. For experimental aircraft use only.

Everything needed to replace one magneto on a 4-cylinder experimental engine with an E-MAG electronic ignition. Each single kit includes the E-MAG ignition module, a trim-to-fit plug wire harness, the incidental installation kit, and your choice of short-reach (SR) or long-reach (LR) auto plug adapters.

Includes:

  • (1) E-MAG 4-cylinder ignition module
  • E-MAG plug wire harness (4-cylinder)
  • Incidental kit with gasket, MAP fittings, control plug connector hardware
  • Auto plug adapters

FAQs

Do E-MAG ignitions require a backup battery?

No. E-MAG ignitions are self-powered once the engine is running. A built-in alternator takes over at approximately 800 RPM, eliminating the need for a backup battery.

Are e-magnetos a direct replacement for a magneto?

Yes. E-MAG ignitions are designed as a drop-in replacement for traditional magnetos on compatible experimental engines, reducing installation complexity.

How is ignition timing set on an E-MAG?

Timing is set using LED indicators and manifold pressure pulses. The system references top dead center (TDC) and stores timing electronically, eliminating the need for traditional timing tools.

Do E-MAG ignitions require special wiring?

E-MAG uses a simple control plug with connections for:

  • Power (14/28/48V bus)
  • Ground
  • P-lead (kill switch)
  • Optional tach output

Can I reuse my existing magneto wiring?

Yes, in many cases the existing p-lead wiring can be reused, though shielding is not required for E-MAG systems.

Do I need a mode switch (Fixed vs Variable timing)?

  • Optional for normally aspirated engines
  • Required for boosted engines
    • Variable mode allows automatic timing advance based on RPM and manifold pressure.

Why is my engine hard starting with E-MAG ignition?

Hard starting is often caused by over-priming or incorrect starting technique, especially on fuel-injected engines. Adjusting mixture and starting procedure typically resolves the issue.

Why isn’t my E-MAG firing?

Common causes include:

  • P-lead grounded (ignition OFF)
  • Wiring connection issues
  • Incorrect timing setup
  • Sensor alignment problems indicated by LED signals

What is a good core return?

A good core retunr for a factory overhauled Slick Magneto is going to be a current series 4300 or 6300 Slick Magneto. If a new Slick Magneto is purchased, then older series Slick Magnetos can be considered for credit on a case by case basis. 

Does this Magneto come with an impulse?

Check the "Detail" tab of the Slick Magneto that you are interested in buying and the Slick Magneto listed with a "Type: Impulsed" will come up with an impulse coupling.

What are the possible bill backs that I can get on a core return for my Slick Magneto?

There are no bill backs on a core return that is a current series 4300 or 6300 Slick Magneto. 

For a Slick Magneto what is the service time?

According to the Slick Magneto by Champion Overhaul Manual L-1363F, the magneto should be overhauled at TBO, lighting strike, prop strike, sudden stoppage of the engine and immersion of the aircraft.
