My co-founder and I are developing hardware that will read diagnostic information from the OBD2 port on consumer automobiles and upload it to the internet via WiFi once the vehicle is parked. We are currently targeting customers who want an easy way to monitor their vehicle fleets for fuel theft, but we would really appreciate any other ideas regarding application of our technology. Essentially our system retrieves diagnostic information from vehicles (fuel information, engine statistics, etc, generic list here: http://en.wikipedia.org/wiki/OBD-II_PIDs), and then creates web-accessible graphs with the data.Is there data from your car that you'd really like to see? Let us know so we can build it for you! And if you're in the Boulder/Denver area of Colorado and have a car fleet, let us know if you're interested in acquiring a beta device to try out the system (my email is in my profile). We appreciate any advice!
