I was reading about this on Engadget. At $90, I think I'll wait for the reviews and see if it's worth the money.
Interface with your car's on-board computer Your car has a lot more to say than just what its "Check Engine" light can tell you. CarTrip makes you a better listener. If your car was built anytime after 1996, you can plug into its on-board computer and access a staggering array of diagnostic and performance information. That's been great news for tuners and shade-tree mechanics everywhere. But other than the mysterious and seemingly arbitrary "Check Engine" light, there hasn't been an easy way to make that data available to the average driver. Until now. Griffin's CarTrip On-Board Diagnostic Computer Reader is the easy, fun tool that helps you drive more fuel efficiently, save money, and do your part to save the planet. CarTrip's wireless monitor plugs into your car's OBD-II port to record and analyze data from your car's on-board computer, then displays it on your compatible smartphone using a friendly (and free) little app called CleanDrive. CleanDrive monitors your car's performance, collecting data like fuel consumption, acceleration, top speed and engine diagnostic codes as you drive. CleanDrive crunches the numbers and displays your "Carbon Score" in an easy-to-understand format on your device's screen. Instantaneous trip and long-term averages are recorded to give you a clear picture of how your driving habits impact the environment and the efficiency of your car over time. In addition, CleanDrive will display and reset the diagnostic codes sent by your car's on-board computer, so you can know what the "Check Engine" light is really saying. Your car's computer has a world of information to share that can help you maintain your car and become a better driver. CarTrip by Griffin tells you how. Features Wireless car computer monitor, compatible with most passenger vehicles built since 1996 Wireless On-Board Diagnostic II reader/logger interfaces with your mobile phone or smartphone via Bluetooth Gathers OBD-II data including acceleration, top speed, fuel consumption, fault and pending codes CleanDrive App (a free download) analyzes data and displays it instantaneously in an easy-to-read graphic format Instantaneous trip and long-term data analysis equips drivers to drive more fuel-efficiently Compatible with: iPhone, iPad, iPod touch running iOS 4.0 or later Automobiles built in 1996 and later which use an OBD-II port to interface with their on-board computers
