Has anyone bothered to look at the time beforeTDC instead of degrees.I think you'll find the curve to be quite interesting.Just a though.Dwight
Good morning,Your recent letter keeps interrupting my normal breakfast routine.I keep thinking about what you have written over & over again.With regards to my simple ignition system.My question, why is it that when I set the ignition timing according to the manufactures specification that the engine does not rev freely?I got around it by advancing the attack angle physically, that is, by advancing the hall sensor, so that is will see the magnet earlier by about 30 degrees BTDC. For the last say 6 months I have known that it is not the processor, the Ardino is doing its duty & doing it well.I compromised, I physically patched up what I should of written inside my sketch.Because I have not allowed for the period of TIME for COIL EXCITATION!RegardsDafydd Claud.
This can be done several ways even with RC, but the most precise is using a PIC, I suppose you could use an Arduino as well but so far I have never seen it done.
Hi, Well +/- 16uS is just under 2° at over 9000 rpm so that is pretty crude timing.
