Hi there I had been looking for something like this.
Update for win8
Auto connect to an elm obd device to obtain a code, then automatically display the meaning from your db
Thanks for your work in posting the OBD-II codes. I was wondering if you knew how to get access to codes like MPG, Odometer, etc. from the ECU of a car? I didn't find those fields in the text files you have posted and they mostly seem like diagnostic codes as opposed to values for other fields.
