Our boards look same because they have to fit under the cap. but that's it. If you remember gefr put together a bench test. That was similar to Dr Bean's. My system just tries to pump the WOT amount of fuel and when the bike was not WOT the pump just didn't cycle as far and everything is okey dokey, except my generation one and to a lesser degree generation two got a bit warm. My gen 3 runs about as cool as it can and still try to pump WOT fuel. gefr's bench test and Dr Bean's was/is optical. gefr's concept is easy in that the toggle action of the points which gefr's optics "watched" gave the right delay. Dr. Bean's watches the pump shaft. I don't know Dr Beans electronics but I hope he accounted for the toggle delay or "dead band" in his circuit. I suppose that even if he didn't it would still work fairly well. NTL I believe optical is better than my approach in general. For sure Dr Bean's kit will not run warm at low speeds like mine does.
