What this calibration identifies
The 89663 part-number family is associated with Toyota engine control software. The complete 89663-60N73 identifier distinguishes this entry from other calibrations in that family, but the catalog name alone does not establish the exact engine, market, model year, or the change made in this particular revision.
No stock or modified behavior is named in the filename. It therefore identifies the main-flash record without describing a specific tuning change or additional feature.
