What the identifier indicates

The related catalog entry is 89663-30660. The additional A_MOD label distinguishes the named file from that base identifier and suggests a modified variant. The label does not identify what was modified or establish a stock equivalent.

An engine control module uses calibration data to manage functions such as fuel delivery and ignition timing. The identifier alone does not establish which of those functions this particular file changes, its vehicle application, or its compatibility with a specific controller.
