What this calibration identifies
The complete identifier 89663-33831 distinguishes this calibration from other files in the same part-number family. The catalog entry identifies the engine and vehicle, but it does not name a specific software change or describe a modified variant. General ECM functions should therefore not be read as changes introduced by this particular revision.
For diagnostic or catalog purposes, the full identifier is more useful than the 89663 prefix alone. The prefix points to the software family, while the remaining digits identify the individual calibration entry.
