What the file label indicates

The base identifier 89663-02482 identifies the calibration family in the catalog. The filename adds TUN, indicating a tuned or modified variant, and EVRO2, a label commonly used for a Euro 2-style emissions modification. In practice, such a modification may change emissions-related diagnostics, but the filename alone does not establish exactly which checks or controls have been altered.

The identifier does not establish a specific vehicle application or describe the changes from stock. The engine controller’s general responsibilities should not be confused with confirmed changes made in this particular file.
