What the filename identifies
The base identifier, 89663-0C821, links the file to a Toyota engine control calibration record. The MOD suffix labels this file as modified rather than stock. The additional E2 label distinguishes the variant, but the catalog name does not establish what change it makes.
The engine controller's general role should not be confused with a verified change in this file. The identifier alone does not establish the vehicle application or which engine-control settings were altered.
