EIS-41000T Twin Engine Aircraft; Lycoming 4cyl Engines, Standard Rotation
Direct Drive (non-impulse coupled) Magneto Replacement
The EIS-41000T Electronic Ignition Kit is a fully STC'd kit for most Lycoming Standard Rotation 4cyl engines installed on twin engine aircraft. Replacing one magneto with the EIS-41000T will typically improve fuel economy on average by 10-15% (many operators have reported consistent fuel savings of 1gph or greater). Additionally, there will be an improvement in horsepower, smoother engine operation, and improved high altitude performance. The EIS-41000T adjusts spark timing automatically by way of our MAP Sensor - timing is adjusted with altitude. Most parts on the EIS-41000T are not life limited (the MTH is recommended to be changed at overhaul of the engine; spark plug wires on a regular interval) - this combined with reduced spark plug fouling means lower maintenance costs. This kit can be used on either 12V or 24V systems.
Kit includes: all the required parts to replace one direct drive magneto (typically, the right hand mag) in most 4cyl Lycoming, standard rotation engines installed on twin engine aircraft. (Please refer to the eligibility schedule to verify the system can be installed on your engine - Note: aircraft & engines are being added regularly). ). You will have to order two kits in order to completely convert a Twin Engine Aircraft – please verify whether or not your aircraft has counter rotating props to make sure you order the correct kit. Please call Electroair Tech Support if there are ANY questions.
