What the identifier and variant label mean
The base identifier 89663-30C02 identifies the catalog calibration. The MOD label marks the named file as modified rather than a stock file. E2 is a variant label, but the filename alone does not establish what change it represents or how the modified calibration differs from the original.
An engine controller generally manages functions such as fuel delivery and ignition timing. The identifier does not establish the exact vehicle application or a specific change made by this modified file.
