Catalog filenames
The identifier appears as 89663-YWF30.bin and 89663-YWF30 (2).bin. The second filename repeats the same calibration identifier with a numbered suffix. That suffix alone does not identify a modified variant or establish a difference in software content.
The complete identifier is useful when comparing a file with a vehicle’s recorded calibration. A matching filename by itself does not establish compatibility or describe what a particular revision changes.
