What the calibration controls
The engine control module uses calibration data to determine how the engine responds to operating conditions and driver demands. Its software helps balance drivability, fuel consumption and emissions. A calibration identifier can distinguish one software application from another, but the filename alone does not show which settings this file changes.
The (1) suffix is part of the catalog filename. It does not identify a stock or modified variant, a vehicle model or a software revision history.
