What the filename identifies
The 89663-60E72 portion identifies the catalog calibration. The _MOD_E2 suffix labels this file as a modified variant, rather than establishing it as the stock calibration. The filename does not explain what “E2” changes or how the modification affects vehicle operation.
An engine control module uses calibration data to manage engine operation, including fuel delivery and ignition under different operating conditions. That general role should not be confused with a documented change made by this particular file. The catalog entry does not establish its exact controller application, vehicle fitment or modification behavior.
