SureFly Tech

SureFly packs a lot of tech into a housing no bigger than a traditional magneto including:

Intelligent Timing Advance

All SureFly SIMs can be configured to operate in either fixed or variable timing.  Variable timing controls spark advance up to 38º before TDC as determined by manifold pressure and RPM (engine power setting). Each engine's base timing advance is read off the data plate and set into the SureFly Ignition Module or, "SIM" at installation.   The timing advance schedule is hard set at the factory,  when the SIM is manufactured, to provide the highest possible combustion efficiency.

To operate the SIM in variable timing mode, the engine onto which the SIM is installed must comply with the following requirements:
  1. Normally aspirated,
  2. Have Cylinder Head Temperature (CHT) monitoring capability,
  3. Use minimum of 100-octane low lead aviation fuel.

No Mechanical Points

Not only are points and condensers a point of failure in magneto ignitions, so are rotors and caps as they carbon track and provide alternate paths to ground as resistance builds in the system.  That's why SureFly utilizes none of these antiquated technologies.  SureFly components are all solid state and industrial-grade electronics.

The result is zero maintenance, zero overhauls, no rebuilds, and no maintenance costs whatsoever!  Nothing to wear.  Nothing to maintain.  Run it to 2,400 hours of SIM operation.
