What the calibration family controls
Engine control software interprets sensor signals and manages functions such as fuel delivery, ignition timing and emissions controls. Its settings affect how the engine responds under different operating conditions. The identifier in this filename does not establish which of those functions this particular revision changes.
The (1) suffix is part of the catalog filename. It does not, by itself, identify a stock or modified variant, a vehicle model or a compatibility range.
