Well I dunno if I would say no advantages. I would agree that it will be performance wise just like mechanical advance. I had the mechanical advance on my Brisson 2.4 and changed to synchrospark. The reason was the mechanical likage kept binding no matter what I tried to free it up. So the electronic advance system will eliminate this potential. I suppose that it is possible for it to open up it's own problems but after a couple of years of use mine is still flawless and a good investment.
