They have gone to all the effort of installing dual ECU's, yet both ECU's run off the same engine sensors. A faulty pressure or temperature sensor would have the same effect on both ECU's.
That is interesting; a feature that would never survive a decent System Safety Assessment during a pukka certification process.
Thing is, they all have potential single points of failure, and whilst d-motor could , and may well do in the future, have fitted duplicate senders, Rotax can't duplicate the gearbox they need as a result of opting for small cc's combined with higher revs.
Having said that, the A65 at the start of the thread only had one carb and one fuel pump.
The origins of dual magnetos probably only stems from how unreliable they were, I doubt they started fitting them for the tiny flame path gains from two sparks!
The quickest way to fall out with people is, discuss politics.
