Ok tried everything I can but at 3700 it cuts off the rear cylinder spark, tried switching coils over on wiring but still the rear cuts out, so coils plugs etc proved ok, pick up is a single one going into a hole in the top of the stator cover, ecu is the Paso type magnetti marelli digiplex 2s med442, I think it must be the problem, can anyone confirm this has anyone got one or know a supplier and can I change the whole thing to maybe a 900 monster system or other fix?
it could be worth your having a look at ducatipaso.org - resource for Ducati Paso 750, 906, 907 IE, 750 Sport . There is a lot of knowledge and information about the Marelli Digiplex ignition on there.
Will do, tried everything else got basically a complete ignition system on order now and will replace everything in turn
