Can you do everything a factory OBD too can do with this?

It's often said that a factory scan tool(such as the type used by a dealership for specific brands) is unmatched by after market scan tools in the detailed information and amount of control you have over a vehicle being serviced.

My guess is that the amount of information given by the factory tool is unmatched not because of the hardware, but entirely due to the software that knows the proper sequence of sets of commands to issue in order to do specific diagnostics and an ability to turn the raw data from vehicle into that can be comprehended by techs.

Is there anything a factory tool can do that you can't do using this

The big feature lacking in most aftermarket scanners is the programming, firmware upgrade, and command functions available in factory units such as the TECH II.
