What the filename identifies
The related catalog entry is 89663-02G40. The longer filename retains that identifier and adds -B_MOD, identifying it as a modified variant. The label does not specify which settings or control functions were changed, so it does not establish a particular performance or drivability feature.
The catalog identifier does not establish an exact vehicle application or a revision history. The engine controller’s general role should therefore not be taken as evidence of a specific change made in this file.
