I emailed Cody at BFM and he responded with:
Our cable works just like the tacrix 1.3, although it uses a generic driver system compared to the ECUflash driver pack specific to tactrix. Our cable will log, flash, pull maps, and read learning views with no problems.
This cable is in the same case/frame as any other OBD2-usb cable including the vag cable. What makes it different is the way we wire the chip inside, common issues with vag cables is having to run 12v wires all over the place to activate the cable. With ours as long as your cigar fuse is ok, its a plug and go just like the V1.3 cable.
