Two clear options: a one-time online dump service for a single fix, or the full FCA PROXI Tool for advanced editing, OBD work, and a professional workflow.
What it is: you send a dump/config buffer, select the needed Fast Parameters, and receive a checksum-correct output file back.
What it is: the complete FCA PROXI Tool with advanced editing, comparison tools, OBD module, and a workshop-friendly Garage.
If you need a single dump edit, the online service is enough. If you need advanced editing, OBD work, or multiple vehicles, the lifetime license is the right tool.
