What the filename identifies
The full identifier combines the base calibration number 89663-33D11 with the suffix _MOD_E2. The MOD label indicates a modified variant rather than a clearly identified stock file. The filename does not establish what E2 changes, so it should not be treated as proof of a particular performance or emissions modification.
An engine ECU uses its software and calibration data to interpret sensor inputs and command engine functions. The exact vehicle application and the changes in this modified file are not established by the catalog name alone. The related 89663-33D11 entry identifies the base calibration family, not a confirmed compatibility list for this variant.
