What the control module does
An engine control module manages engine operation using sensor inputs and programmed calibration data. Depending on the application, it can control fuel delivery, ignition timing, emissions-related functions and responses to driver demand. Those are general controller functions, not confirmed changes introduced by 89663-30T60.
The complete identifier distinguishes this catalog entry from other calibrations in the same family. A matching prefix alone does not establish vehicle fitment or interchangeability.
