What the filename identifies
The related catalog entry 89663-33E60 supplies the base calibration identifier. The longer filename adds -B_AVT_Stage1 and the .bin extension. “Stage 1” identifies this file as a named variant, but the filename does not specify its tuning changes, performance gains or intended hardware.
Engine-control calibration affects how the controller operates the engine under different conditions. The presence of a Stage 1 label does not establish which maps or control limits were changed in this particular file, and it should not be treated as a stock specification.
