Dyna III Ignition same as BMW?
« on: January 04, 2019, 10:33:30 AM »
Is the actual Dyna III ignition box (dont care about the pickups) the same as for a BMW?  Can I buy a second hand Dyna III off a BMW and swap the box out for my one on the Guzzi?

I don't think so, Kev. Not unless it's the Dyna for dual pickups that can be adjusted separately. But I don't have any experience trying to do that. You might get a hold of Dyna and ask them.

The BMWs have one ignition circuit that fires both spark plugs every time. Each cylinder fires on the exhaust stroke and that's why it's called a wasted spark system.

The Guzzis have to have two ignition systems fired independently. So you'd either need two Dyna units or one designed to handle two separate circuits.

Thanks WS,  Of course your correct, I knew that. Also Dyna are showing different part numbers.

Kev - there was a dyna for the airheads that used two separate pickups, and that system wasn't wasted spark. I don't think they offer it now. If that's the one you have then it's possible it could work on a goose.
