It would still maintain a wasted spark system, ignition curve would be through a 3d table.
5 tooth 4 coils = 1 odd tooth for a sync 1 tooth per cylinder
The coils fire twice per crankshaft revolution, 180 degrees apart. If you're still using wasted spark and four coils, then you are firing two coils at a time, you need two triggers and the connectivity determines which coils are firing.
I don't understand the need for a sync pulse. Why is any cylinder's needs different from the others?
Current consumption is more dependent on the coils used then the ignition unit itself.
True, unless your unit does more than simply switch 12V power on and off like the points do or the Dyna does. What are the advantages to your scheme?
Any idea of what people would be willing to pay?
For an electronic switch? That depends on your marketing skills. What benefits do you expect to provide?
I'm still using points, 'cause I think the Dyna unit is and always has been, too expensive for what it does. But, there are lot of people who think it's the bee's knees. Or, even pay far more for a digital unit with a rev limiter, and adjustable advance.
I think you are going to have to sell reliabilty pretty hard. The points are as reliable as dirt, and can be made to function even in Tierra Del Fuego. If your unit packs up how long to make it work again?
Cheers,
