What the file label identifies
The MOD label indicates a modified variant rather than an explicitly stock file. E2 is an additional variant label, but the catalog name does not establish what it changes. In particular, the filename alone does not confirm a change to an emissions system or identify a specific driving effect.
The related catalog entry 89663-33702 supplies the base identifier. It does not establish an exact vehicle application, controller hardware compatibility or revision history for the modified file.
