Engine-control role

The engine control module uses calibration data to manage diesel engine operation, including fuel injection in response to operating conditions. That control affects how the engine starts, responds to the accelerator and runs under load.

The identifier and filename associate this entry with the engine-control system. They do not establish a particular drivability fix, emissions change or modified feature for this calibration. The catalog entry also carries no stock or modified variant label.
