Hence the Clone Tech II unit you get will already be loaded with the most current firmware, and for most of the stuff you going to use the Tech II clone, will just be using the unit by itself without being connected to a laptop.Īlso the cracked copy of Tis2000 that you get with the clone model, does not have to be connected/logged into GM to use it for 99% of the stuff (do not need an account with GM). So the only way that even a clone MDI is going to work, is to have a subscription to GM (Few $K a year) to allow you to use the GDS2 software that has to log into GM each time it used instead. Now the glitch on the MDI regarding cloning it, since it has to use the GDS2 software for the pass through only device, GDS2 software has not been cracked like Tis2000 software has been instead. As for the MDI’s firmware, they will cover not only the new cars, but the cars that the old Tech II’s used to cover as well. Since GM did not make upgraded firmware to flash into the Tech II’s to cover these cars like C7, then it’s a MDI that is needed instead. If you do need to reflash something, it’s done via Tis2000 with the Tech II as the pass through device. So in regards to the vets, Tech II clone will cover all the C6 cars and older since the last of the updated firmware on the unit covers from here back.

Its also faster to use than having to press buttons on the Tech II for basic commands during diagnostics as well. Part 2: Why GM MDI instead of Tech II scanner?Īs for why GM is going to the GM MDI and GDS2, instead of using a Tech II with TIS2000 software, because the MDI with GDS2 flashes a hell of lot faster when you have flash a new module with either it orginal firmware or upgraded firmware. In fact, the card flash socket was missing from the board. I bought a cheap one and it only worked with usb. So far, Chinese clone GM MDI with squ wifi cardģ: wifi is not working but works fine with USB Tested by my own, works with Saab 9-5, 2003, 3.0 Already tested.Ģ003 year too old – not interesting for me. Simply pressed OK when Candy detected and all worked. If you want to program by using GM MDI, you need to buy account at GM MDI official site:ĭevice is compatible with Tech2Win (Opel, Hammer)ĭevice is not compatible with SAAB via Tech2Win It is programming online, support offline programming for Opel Chevrolet. It is cheap (238eur with software and free delivery). As you can see, GM MDI is the best GM 2009 – 2019 diagnostic and programming tool.
