What the identifier establishes
The complete identifier distinguishes this catalog entry from other files in the same part-number family. The family association does not, by itself, establish the exact vehicle, engine or changes contained in this calibration. The .7z ending identifies the archive format rather than a vehicle function or a stock or modified variant.
