Related catalog identifier
The related entry 89663-53Q30-A retains the full calibration identifier with an -A suffix. The suffix distinguishes the catalog name, but it does not establish whether the file is stock or modified or describe a change in vehicle operation.
The calibration number alone does not identify a specific software revision history or confirm compatibility with a particular vehicle.
