I have 2 different systems.
http://www.obd-2.com/
AND
http://www.scantool.net/
The OBD-2.com version seems to work better on Asian and domestic cars, but I could NOT get it to work on VW, Audi or BMW
Hence the Scantool.net tool
Works on German and domestic cars, but not so well on Asian imports (I’ve had problems with Hyundai and Toyota)
They both work well when they work. Both cost about $100 for the software and cable.
I’m a little more partial to the OBD-2.com version, simply because I like the software/inference better.
The documentation for both products is abysmal. both are “learn as you go” types.
