What the identifier tells you
The filename combines the 89665-0C881 part-number form with a trailing 00. The full identifier distinguishes this catalog entry from other files in the same controller family. It does not, by itself, identify a specific software change or a modified feature.
No stock or modified variant label is present in the filename. Vehicle fitment and the effect of this exact calibration require confirmation against the relevant controller and service records.
