What the identifier tells you
An engine control module uses sensor information and calibration settings to determine how to operate the engine. Depending on the vehicle and powertrain, its responsibilities can include fuel delivery, ignition timing and emissions control. Those are functions of the controller family, not confirmed changes made by 89663-06Q30.
The complete identifier matters when comparing calibration records. A similar 89663 prefix identifies the broader software family but does not establish that two calibrations serve the same vehicle or contain the same settings. The exact application and any revision-specific behavior of 89663-06Q30 are not established by the identifier alone.
