What the catalog identifier indicates

The related catalog entry 89663-0CA63 matches the calibration identifier in the filename. The .bin extension denotes a binary file, while the trailing hyphen is part of the listed filename. The catalog name does not identify a vehicle model, engine, controller hardware number or stock or modified variant.

An engine control module uses sensor readings and programmed calibration data to regulate engine operation. Those general responsibilities do not establish what this particular revision changes or which vehicles it fits. The complete identifier is useful when comparing service or controller records, but a matching part-number family alone is not enough to confirm compatibility.
