What the filename identifies

The related catalog entry 89663-47120 supplies the base calibration number. The longer filename adds A_MOD_E2, with MOD indicating a modified variant. The meaning of E2 and the specific modifications are not documented in the available catalog entry, so they should not be interpreted as a confirmed feature or emissions change.

Although the 89663 family points to engine-control software, a calibration number is not by itself a complete vehicle fitment record. The full identifier is useful for distinguishing this file from other calibrations and variants in a service or firmware catalog.
