It's not a J2534 device. You can't get the GM software from the GM website for a specific VIN and flash a new PCM. You can't use it as a pass-though to run OEM software that the dealers provide under right-to-repair for the aftermarket.
Most of those tools have basic Programmable Module Installation on a limited basis. PMI ***** the data out of the old module, and injects it into the new module. Varying coverage and function exist, and this is generally for stuff like BCMs, ABS modules, smaller stuff. Not emissions control items like PCM/TCM. Modules also have the ability to be "woken up" or network "handshakes" performed. I forget the name for the latter, Chrysler uses it, but it basically has all the modules communicate within a network and make sure they're all happy with one another and have the specific VIN and IDs logged between modules. Proxi Alignment it's called? Some coding functions and reset functions will exist to learn new parts, clear learned values, etc.
My opinion is that the HF tools are running launch software, if that gives you any clarity on capability.
