What the EVRO2 label indicates
EVRO2 is a variant label in this filename. It suggests a Euro 2-related emissions variant, but it does not identify the specific calibration changes or confirm compliance with an emissions standard. The catalog name does not identify this file as a stock calibration.
The complete calibration identifier is useful when comparing records because similar Toyota part-number prefixes can cover different applications. The repeated 89663-02J22 in the filename is part of the catalog name, not evidence of two separate calibrations.
