Not sure what electronics you guys intend to use but for simplicity( all in one), the Schnitz Pro Series 2 ignition controller is the only way to go. This box one does it all- progressive timing retard/advance, progressive nitrous controller, auto shift, auto tranny controller, 2 step rev limiter, and a host of other features you would likely never use. I've got them on 3 out of our 5 bikes. They are simple to wire- it comes with full instructions and a color coded wiring harness. Why use 4 or 5 seperate Dyna devices/nitrous controllers when box will do it all at the turn of the knob and press of the button.
The attached pic is one on my 8.88 index bike.
