What the Stage 1 label indicates
The filename identifies this file as an AVT Stage 1 variant. In automotive tuning, Stage 1 commonly describes a modified calibration intended for a vehicle with relatively limited hardware changes. The label does not specify which engine-control settings were changed or what performance effect this particular file produces.
An engine control module uses calibration data to manage functions such as fuel delivery, ignition and emissions control. Those are general functions of the controller family, not confirmed changes in this Stage 1 file.
