Reading the calibration identifier
The complete identifier 89663-02162 is the useful catalog key. The related catalog entry uses that same identifier without the (2).bin filename suffix. The suffix identifies the listed binary file but does not establish a modified variant or a specific software feature.
The part-number family suggests an engine-control association, but it does not by itself identify a vehicle, engine, transmission, or change introduced by this calibration. Those details require matching service or calibration records for the complete identifier.
