What the filename identifies
The related entry 89663-02X40 supplies the base calibration identifier. The longer filename adds _AVT_Stage1, a variant label that distinguishes this file from the base catalog entry. “Stage 1” commonly denotes a modified calibration, but the name alone does not establish which settings were changed or how the vehicle would behave differently.
An engine control module uses calibration data to govern functions such as fuel delivery, ignition and emissions control. That general role does not confirm a specific change in this revision. The filename also does not identify an exact model, engine or compatible controller.
