Honestly I do look forward to a programmable EFI system for 2 stokes. I have been using programmable EFI on my hotrod for >10 years and wish I had those benefits on my dirt bikes too.
The only people that want EFI are manufacturers unless you want to change map on the fly. Which I don't. BTW I have 2 EFI bikes and I wish they didn't!
I have not tuned bike EFI yet but if they come up with a system that has the adjustable functions and parameters like they do for cars like in the FAST XFI or Holley system, it makes it possible to adjust for altitude, temperature and engine load. Don't get me wrong it takes time to get your tune right but once you do, it makes life much easier. Plus your fingers don't smell like gas when typing on a keyboard.
I know two people with efi 2 strokes. One with a Link kit, one with Electrons kit. Both have spent months trying to sort it with soggy info from supplier's as no real experience for 2 strokes complete with sw bugs.. One has it pretty sweet the other is floundering occasionally making jumps. Both are smart motivated guys.
Making it run at a constant speed hasn't been the issue.
