If that Rotax is not sealed, has screws on the back, it probably can be looked into. I mean, if it is all sealed in epoxy, forget it. However, it could be a prom pin floating out or who knows? Motherboard cooked? Broken prong at one of the legs that both harness connectors snap over the ECU? Did you poke each pin to see if one lost a tight fit?
Well that's passed half of my lunch break. I didn't even notice the foul tasting cupasoup. Thank you.:thumbup
It's not a rotax, it's a Siemens ECU.
