What the controller does
An engine control module uses sensor inputs to manage engine operation. Depending on the application, its calibration can influence fuel delivery, ignition timing, throttle response and emissions-related controls. These functions affect how the engine starts, runs and responds to the driver.
The related catalog entry 89663-60J10 supplies the calibration identifier used in the filename. The STOK label indicates a stock variant rather than a named modified feature. It does not identify a particular software change, performance modification or service-bulletin update.
