What is a spark ignition module?

A spark ignition module is an electronic component in internal combustion engines that controls the timing and delivery of the spark to the engine's spark plugs. It ensures optimal ignition timing for efficient combustion, improving engine performance and fuel efficiency. The module receives input from various sensors to adjust spark timing based on engine conditions. It's commonly found in gasoline engines, particularly in vehicles equipped with distributor-less ignition systems (DIS).
