1. A system for controlling operation of an electrically actuated fuel injector, the system comprising:
a microcontroller;
a pre-driver unit; and
a power unit; wherein:
said system is configured to be connected to said electrically actuated fuel injector via two wires from said power unit;
said pre-driver unit is connected between said microcontroller and said power unit;
said microcontroller is configured to send data to the pre-driver unit;
said data comprises both injector activation pulse data and auxiliary data for the electrically actuated fuel injector, wherein the auxiliary data is not an activation pulse;
said pre-driver unit is configured to receive said data and control the power unit dependent on said data such that the power unit is configured to output a corresponding signal along both a first wire of said two wires to the electrically actuated fuel injector such that said injector activation pulse data is sent to said electrically actuated fuel injector along the first wire of said two wires and such that said auxiliary data is sent to said electrically actuated fuel injector along the first wire of said two wires; and
wherein said auxiliary data is sent asynchronously in time relative to when said activation pulse data is sent on the first wire of the two wires.
