What the calibration identifier tells you
The catalog also lists the identifier 89663-60422. That complete number distinguishes this calibration from other files in the same software family. The related catalog entry does not name a vehicle, engine, controller model or modified feature, so the exact application and the changes made by this calibration cannot be established from the identifier alone.
The (2) in the filename does not identify a specific stock or modified variant. It may simply distinguish one copy of the file from another.
