What the identifier tells you
The related catalog entry lists 89663-02G42. The complete identifier is important when comparing calibration records because a similar prefix does not establish the same vehicle application or software behavior.
The (2) suffix appears in the filename, but the catalog entry does not identify it as a stock or modified variant. It should not be treated as evidence of a performance change or a particular revision.
A vehicle, engine, control-module part number, or service bulletin would be needed to establish the calibration’s precise application and any change made by this version.
