Calibration files
The catalog lists 89663-0CA32.bin and 89663-0CA32-.bin. Both filenames carry the same complete calibration identifier. The extra hyphen in the second filename does not, by itself, identify a stock or modified variant or describe a software feature.
An engine control module generally uses calibration data to manage functions such as fuel delivery, ignition and emissions control. That general role does not establish what this particular revision changes or which vehicle it fits.
