Digital Ignition ZDG3 - Ducati Twin 350-500ccm

The digital ignition system ZDG3 replaces existing breaker points and advancer by purely electronic components. The signal recording is done by Hall sensors. Please do not confuse this ignition system with a characteristic field ignition. The only thing in common is that microcontrollers are used. A characteristic field ignition takes into account many other influences such as knock sensors, ambient temperature, injection volume, etc. What is the advantage of an electronic ignition? Once maintenance-free, because no wear of mechanical components can affect the long term the settings. And then even the constant ignition coil boot from about 5mS, which ensures a uniformly strong spark in every speed range. With a mechanical centrifugal distributor the dwell angle always remains the same, what has resulted in, that in the low rpm range much 'is fried too much current in the coils, and at increasing speed the recharge time of ignition coils always shorter and thus also the spark is always weaker. To protect the coils after engine stop, the ignition current is switched off after approx. 5 seconds.
