Mate vt/vx commodore v6s are not obdII. Yes they have the obdII plug but do not run the protocol. So those elm327 will not work.
I came in to say this and save you a few bucks. I've got an elm if you want it lol but it's useless for VT and VX. I do however have a bunch of software programs for your computer that came with the device and I would expect at least some of them would work with other devices like tech2 etc so once you get your device if the software is inadequate/incompatible/boring then I can hook you up with copies if you want.
