What the identifier tells you
The complete identifier distinguishes this calibration from other entries in the same number family. It does not, by itself, establish which engine, vehicle model or software change it covers. Matching a similar prefix is not enough to confirm that another calibration is interchangeable.
No stock or modified variant label is identified for this entry. Its exact application and revision history require a matching catalog or service record.
