According to the Cobb website:
An AccessPORT can be uninstalled from a vehicle by selecting the Uninstall option from the main menu of the AccessPORT. Once this process is complete, the AccessPORT can be installed on any other vehicle that particular part number supports. If an AccessPORT has not been uninstalled from the previous vehicle, or the previous vehicle was totaled or stolen, the AccessPORT can be relicensed, or reset back to an uninstalled state. Please contact our support team for more information about this process.
From this, it looks like it is not possible to install the AP on a different model as it is most likely a different part number.
