What the calibration identifier tells you
The .bin filename denotes a binary firmware file. No stock or modified variant label appears in this catalog entry, and the identifier does not establish a specific performance modification or service update.
For diagnostic or parts-matching purposes, the full calibration identifier is more useful than the shared 89663 prefix. A matching family alone does not establish that two calibrations are interchangeable.
