Engine control and the Stage 1 label
An engine control module uses calibration data to manage functions such as fuel delivery, ignition timing and emissions control. Those settings influence how the engine responds to driver demand and operates under changing conditions. The specific behavior of calibration 89663-06E72 is not identified by the catalog name.
The filename label AVT Stage 1 indicates a named modified variant rather than describing a specific factory service revision. “Stage 1” commonly refers to an initial level of performance tuning, but the filename does not establish which settings were changed or what effect they have on power, drivability or emissions. The related catalog entry 89663-06E72 identifies the base calibration without that variant label.
