What the filename indicates
The filename labels this as an AVT Stage 1 E2 variant. “Stage 1” commonly describes a modified engine calibration, but the filename does not identify its tuning changes. E2 is also a variant label here, with no documented meaning in the available catalog record.
The related entry 89663-33E33 supplies the base calibration identifier without those variant labels. It should not, by itself, be read as proof of a stock file or of compatibility with a particular vehicle.
