What the filename identifies
The related catalog entry 89663-33A53 supplies the base calibration identifier. The longer filename adds TUN_E2_V2, a variant label that distinguishes this file from the base entry. TUN suggests a tuned variant and V2 suggests a version designation, but the filename does not establish what was changed or how it compares with stock software.
The E2 label is not enough to identify a specific emissions change or other function. Confirming the file’s effects or compatibility would require additional application information or a comparison with the relevant original calibration.
