Understanding the file identifier
The related catalog entry 89663-02510 identifies the calibration family, while the filename associates this file with a Toyota Corolla. The available identifier does not establish a specific model year, engine or vehicle configuration.
The MOD1 label indicates a modified variant, but it does not describe the changes made. The meanings of E2 and iv, and their effect on engine operation, cannot be established from the filename alone. The controller’s general engine-management role should therefore not be treated as evidence of a particular change in this file.
