What the filename identifies
The MOD label identifies this file as a modified variant. The filename does not identify the changes, so a specific effect on engine operation cannot be attributed to it. The related 89663-0C790 catalog entry provides the base identifier but does not establish a vehicle application or confirm a separate stock file.
The complete calibration identifier is important when comparing records. A similar 89663 prefix alone does not establish that another file has the same application or software behavior.
