I bought this at Walmart. The cable cost $99 and basic app is free. (sure you can get it for less online)
I have never used a scanner but this one seems easily upgradable due to it being an app.
Motor Trend and Popular Mechanics both rated the cable and app highly. Thought I would give it a try and review.
Not much info available about what it actually does with our cars. There is a disclaimer that says that not all functions supported by all manufacturers, so I thought I would post my results.

I tried googling how to make your own cable... No luck.

Doug - would you say there are smarts inside the cable? or is it just a pin for pin adapter? Maybe the OBDII to USB chips would come into play?
yes, there is a chip inside the cable. Cant remember the chip # though.

One side note. There is no manual for the DashCommand software and nearly zero online support. It take a long time to get a response on the forum.

The chip apparently, is ELM327

Seems fuel level is not reported through the OBD connector on our cars.

Overall, I like the program DashCommand. Today I got as usual, the code P0440. GpPoint saw it as pending and DashCommand did not. Finally it came in solid. Both saw it and using GoPoint I was able to clear the CEL. (light stayed on then did not come back on after restart)
I can do the same thing by pulling a fuse mind you......
It was interesting that DashCommand did not see the pending code but GoPoint software did.
Both apps have their strengths and weaknesses. (ain't that always the way it is?) lol
