Abstract
In at least some implementations, an ignition system for a combustion engine includes analog circuit components arranged to control ignition events at an engine speed below a first threshold of engine speed and a microprocessor to control ignition events at engine speeds higher than the first threshold. Hence, ignition can be controlled at lower engine cranking speeds to facilitate starting the engine at lower engine rotational speeds.
