OBD Tutorial.

Im not sure what ELM is, but i think i have a real question.

If i buy a OBDII to USB cable, can i plug it into my laptop and see live stats of whats going on with my sensors; see and clear any trouble codes, and potenially even unlock the firmware and upload my own.

I have some experience with the arduino platform, and some java and python programming.
One thing i would like to do is send my oxygen sensor information into an arduino and create the ability to adjust the readings on the other end. thus giving me the ability to change how the injectors behave to a small degree.
