I was in megasquirt bussines for more than a year - connectors in this photo is rubbish to say at least. As other connector too. I have some failures on ms ecu before I moved to some propertiary connector to reuse old wiring in car...Dual ECUs with dual sensor suites as Rotax does on their iS engines and we do on Lyconentals. No limp mode in aircraft ECUs since you need relatively high power to maintain flight compared to automotive applications where you only need 20-30 hp to limp home. Most sensors outside of crank sensors are not needed to keep the engine running to get you home safely if you mitigate with defaults.
