An ignition control device having an Electronic Fuel Injection mode and a Capacitive Discharge ignition mode is described. The ignition control device comprises: an output for providing an output voltage, connected or connectable to a load, the load being a fuel injection actuator of an EFI system or an ignition capacitor of a CDI system; and a driver unit connected to the output, for driving the output voltage from a low level to a high level and from the high level to the low level in dependence on an input signal, each transition of the output voltage from the low level to the high level having a low-to-high transition time which is longer for the CDI mode than for the EFI mode.
