Calibration context

Engine control software generally manages functions such as fuel delivery, ignition timing and emissions-related operation. The complete identifier and related catalog name do not establish which of those functions this particular calibration changes, or which vehicle and engine it fits.

The (2) suffix is part of the filename presented here. It does not by itself identify a modified variant or a specific software feature.
