Dyna 111 ignition?

Can I use a Dyna 111 ignition on an 80 KZ1000? I already have Accel coils but need a better ignition. Do I need to find a Dyna S instead or will the 111 work? Thanks

In my opinion, the Dyna III should be more reliable than the S, but it requires finding space for the control box. Either one should work as long as it's made for your bike.
