    At the moment I don't know how to put the Visual Studio code on here which is needed to talk to the Nano. I'll put it up when I get a chance.

  • Ignition System for a Motorcycle about 2 months ago

    Well for 1 thing you most likely won't get sparks or you might get weak ones with the wiring the way it is. The secondary side of the coil should be going to ground (-) and not tied into the ground (-) of the primary this puts undue stress on the transistor. The current wants to flow to the other side of the secondary. 2 don't worry about timing off 1 pulse or RPM, it makes no difference to the motor. My mechanical advance follows the rpm, it does not lead it. If you want you can measure the pulse width if you don't want to measure the time between pulses. If you go with the pulse width then you will have to calibrate the degrees with what the ignition is seeing or putting out. The pulse width will decrease as the RPM goes up. 3. you do not need a vacuum advance on any engine, period! The vacuum advance is there for when the engine is actually running and to retard the timing for starting the engine. The vacuum advance is there to also give the engine a smoother idle which is something you can program into the UNO verses the RPM (lookup table). Basically you do the same as we used to do to set timing, remove the vacuum from the vacuum advance to set the timing like in the old days. On my race car and just about everyone else who drag races and 2-stroke engines do not have a vacuum advance. They either have a mechanical advance or the timing is locked in.
