What the calibration controls
An engine control module uses calibration data to manage engine operation, including fuel delivery, ignition timing and emissions-related functions. These settings help the controller respond to operating conditions such as engine speed, temperature and driver demand.
The identifier 89665-30472 distinguishes this calibration from other entries in the same numbering family. It does not, by itself, show which of those engine-management settings changed in this revision. A matching vehicle and controller record would be needed to establish its exact application.
