What the filename identifies

The MOD_E2 suffix distinguishes this file from the related 89663-0D401 catalog entry and indicates a modified variant label. The filename does not explain what the E2 designation means or identify a specific change from the base calibration.

The available identifiers do not establish an exact vehicle application or controller fitment. They identify a firmware record and its related base calibration, rather than a verified compatibility list.
