OBD-II Port Lock -Tune Saver

OBD-II port/tune saver. This tune saver is designed to keep unauthorized persons from accessing your '96 and newer computer through its OBDII port. It prevents such things as changing programming, changing performance parameters or accessing vehicle specific data such as key codes.

This may work on other vehicles with an OBDII port but we cannot confirm any model other than Ram trucks.
