Engine control calibration context
An engine control module uses calibration data to manage engine operation, including fuel delivery, ignition timing and emissions-related functions. The association with that controller family is tentative for this entry, and it does not establish which of those functions this file changes.
The related catalog entry 89663-60C00 matches the core calibration identifier in the filename. The suffix A_MOD_E2 labels this file as a modified variant, but the filename does not define the modification or establish what E2 means. It should not be interpreted as evidence of a specific emissions change, performance feature or vehicle fitment.
