Standard and Stage 1 catalog labels
The catalog lists 89663-0CA63.bin and 89663-0CA63-.bin as binary filenames without a named modification. Their names alone do not confirm whether their contents are identical or whether either file is an unmodified factory calibration.
A separate entry, 89663-0CA63 stage1, carries a Stage 1 label. In automotive tuning, Stage 1 generally describes a modified engine calibration intended to change performance-related behavior. The label does not identify the specific changes or establish a power increase for this file.
An engine controller’s general responsibilities should not be confused with changes made by a particular calibration. The catalog names do not document what this revision changes or which vehicles it fits.
