I wish Linear Logic would get off their frikin asses and give us something with a decent display. I've had my Scangauge 2 for almost 3 years now and I'm ready for something better.
I think you answered your own question. I think that the price of "plug and play" is that it is using what the OBD II spec is giving to it. I went looking for the volt/amp out of OBD II and found this :

16 pin car OBD2 special connector diagram and applications @ pinouts.ru

OBD II to USB cable pinout and wiring @ pinoutshandbook.com


Question: Can someone interpret the juice coming in from the above schematic?

I went to my car and tried to measure the amps of pin 16 but I messed up. I blew a fuse, not good! Sooooo, I do not suggest that you try this unless you know your electronics (I obviously don't, ).
