Unlike some of my sibling replies, I see(quel) what you did there.

hah. I didn't even realize that I confused my acronyms.

I hold a patent on an improved way of implementing a diagnostic vehicle network interface, basically HW protocol offload for CAN.

Plugging the prototype into a car and getting useful data out of it was satisfying.

You can get them for about 12 bucks and talk to them over usb. Pretty nifty

They are quite convenient, but tend to only "see" generic PIDs. The manufacturer specific diagnostic codes are much more useful.

I've got one and I've got the actual manufacturer scanner, and there is a world of difference in the utility of what is reported (things like transmission oil temperature, which is needed to correctly set the transmission oil level, etc).
