With dealer involved service they always flash computer. It is inconvenient to connect reconnect devices, IE, hypertech, P.C. when technology is available o Bluetooth connection. I'm willing to wager these Co,s will provide the wireless connection. I'm going wait. The connection terminals are not designed for repeated connection, re-connection. The firewall this device disables is to provide a change in Truck settings. The Security module it is pretty much an on off switch. Off allowing programming/On prevent hacking (why the Security module system was developed). This post is not to get readers excited like previous responses. My opinion/observations.
My "opinion" is as follows:
1. Dealers do NOT always flash the computer so that is a strong and inaccurate statement. If the tech sees an update that your vehicle calls for (few and far between) they will flash a module or if a TSB requires a software update then they will do the same if you experience that specific issue. They don't flash for the sake of flashing!
2. If you wait for these devices to go wireless, you'll be waiting a VERY long time. And, if they do, something has to physically connect to the vehicle for the wireless device to communicate with so your thinking is a bit flawed
3. Who are you to say that the terminals aren't designed for repeat connections? As an EE, they look fairly robust to me and I have seen nothing that indicates this will be an issue over time so if you have FACTS, then please state them for all to see. As long as you do not PULL by the wires and disconnect properly they should remain trouble-free
4. The SGM (Security Gateway Module) was designed and installed in ALL FCA vehicles after folks were able to remotely hack into Chrysler vehicles via their cellular connection like was seen on the news. It must be also be connected in order for communications to take place between the OBD2 port and the vehicles various control modules hence why flashing requires it to be connected
