What the file identifies
The MOD_E2 suffix distinguishes this file from the related catalog entry 89663-60F91. It indicates a modified variant, but the label alone does not establish what was changed or what “E2” means. The available identifiers do not establish a specific vehicle application or a particular revision’s effect on driving behavior.
The complete identifier matters when comparing records. A similar-looking calibration number is not sufficient to establish that another file has the same application or software behavior.
