Did you need a vr board to digitize the crank signal? What throttle body are you using, I have so many questions bro. I’m assuming your using mega squirt or speeduino?
Yes I used a speeduino NO2C with a VR conditioner. Throttle body was from a Honda NC700. Intake manifold was a custom fabrication. I can help with any questions you have.
Ignition system was all stock. Speeduino was only controlling fuel. In order to control timing and ignition, I would have needed to add a crank position sensor and trigger wheel. I never got around to it though.
This is truly remarkable work. You should be incredibly proud of the work you've done so far. It's nice to see a Vulcan 750 brought back from almost certain death. Good luck as you continue making progress and please post more updates, I can't wait to see what else you get done. Bravo!
