What the filename identifies
The MOD label identifies this file as a modified variant. The E2 suffix is part of that variant’s name, but the catalog entry does not establish what it changes. The related entry, 89663-30F61, supplies the base identifier without describing a stock file or a specific revision.
The full identifier should be used when comparing calibration records. The part-number family indicates the likely controller role, but this entry does not establish an exact vehicle application, engine or modified behavior.
