What the filename identifies
The related catalog entry 89663-33B51 supplies the underlying calibration identifier. The _MOD suffix labels this binary file as a modified variant, but it does not identify the changes made to the calibration or establish a particular performance feature.
The identifier alone does not reliably establish the exact vehicle application or the behavior changed in this file. The engine-control functions described here are general to the controller family, not claims about a specific revision.
