You still need to know the various CAN IDs, data formats, how to clear error codes, etc. All that required detail is only contained in the MUT software, as far as I know.
Certainly, we'd want a hardware platform more convenient than the actual MUT, which I believe requires ancient Windows versions and the like. So yes, fake in that sense.
