Controller family and application

Engine control software manages functions such as fuel injection, ignition timing and emissions control using information from engine sensors. Its decisions affect engine operation and drivability. That general role does not establish which functions this particular calibration changes.

The identifier alone does not establish an exact vehicle application, engine or revision history. The filename also contains no stock or modified variant label.
