Engine control calibration context

An engine control module uses software and calibration data to manage operating functions such as fuel delivery, ignition and emissions control. Those general functions do not establish what this particular calibration changes or how it affects a specific vehicle.

The related catalog entry uses the same identifier, 89663-02492. The filename suffix (2) does not by itself identify a stock or modified variant. No vehicle model, engine or revision-specific behavior is established by the catalog name.
