What the calibration controls
An engine control module uses calibration data to manage engine operation, including fuel delivery, ignition timing and emissions-related controls. The precise settings and changes in this file cannot be determined from the identifier alone.
The MOD_E2 suffix identifies this file as a modified variant. It does not, by itself, establish what was changed or whether a particular emissions function was altered. The related 89663-02512 entry identifies the base calibration without that variant label.
