Engine control calibration
An engine control module uses calibration data to manage engine operation, including fuel delivery, ignition and emissions-related functions. The family association does not establish which of those functions this particular file changes.
The identifier alone does not reliably establish the vehicle application, exact controller or revision purpose. No stock or modified variant label is present in the filename.
