Reading the complete filename
The filename contains the identifier 89663-07072, followed by EVRO2 and the binary file extension .bin. The suffix distinguishes this file from records identified only by the base number. Its precise meaning and any changes it denotes are not established by the filename alone.
The identifier does not reliably establish a vehicle model, exact controller application or revision history. It also does not establish which engine-control settings, if any, differ from another calibration.
