The Magneto Timing Housing (MTH) version of Electroair‘s Certified Electronic Ignition System for Continental IO-360, O/IO-470, IO-520 and IO-550 six cylinder engines is now available from Ameritech Industries, parent company of Eagle Engines and American Propeller.
The EIS-61000-1M STC’d ignition kit is currently approved for Cessna, Cirrus, Bellanca, Beechcraft, Mooney, Meyers and Navion aircraft, with models being added regularly.

The Electroair direct fire ignition system replaces one magneto with a Magneto Timing Housing (MTH) that feeds the engine position and RPM information to the controller. The controller also receives the input from the MAP sensor, computes the amount of dwell, adjusts timing, and signals the coils to fire directly into the spark plugs.
Typical advantages of the system include: 10-15% increase in fuel economy, smoother engine operation, improved high altitude performance, improved horsepower, reduced hot start problems, reduced spark plug fouling and lower maintenance costs at 500 hour intervals, according to company officials.
Limitations of the previous six-cylinder version of the ignition system are eliminated with the introduction of this MTH system, company officials add.
