DO NOT try to use the more modern version of the software. it will kill the cable.

I bought one of those to play with when I got my first Boxster. It read the DME on my '99 but didn't work with any other modules (did not reset the airbag). It required a Windows XP computer and did not work with later versions. Not saying they all won't work, just be sure to read the fine print (if they bothered to print it).
