What the filename identifies
The related catalog identifier is 89663-52K80. The additional -B (2) text distinguishes this filename, but it does not establish a stock or modified status or identify a specific change in engine behavior.
The exact vehicle application and the functions changed by this calibration cannot be established from the catalog name alone. The engine-control association is therefore a family-level identification, not a confirmation of fitment or a description of this revision’s effects.
