With the Lycoming O-360 in my Grumman Tiger freshly overhauled, I decided it was time to replace one of the mags with an Electroair electronic ignition.
At the time (I started shopping for it and a Garmin avionics package at AirVenture 2017), the investment in the Electroair EIS 41000 seemed risky. Generally skeptical of manufacturer claims of improved performance, I also thought about dispatch reliability (we fly a lot) and maintainability as the system aged.
