What the filename identifies
The suffix AVT_Stage1_E2 distinguishes this file from the base calibration identifier. Stage1 is commonly used to label a modified calibration rather than a stock file, but the filename does not establish the specific changes. The meanings of AVT and E2 cannot be determined reliably from the catalog entry alone.
The identifier does not establish a particular vehicle, engine or compatibility. It also does not show which engine-control settings, if any, this variant changes.
