Just when you thought the iPhone couldn’t do anything else, Griffin Technology has introduced a system where it monitors your fuel economy, maintenance codes, engine performance and more. CarTrip is a hardware and software combination that uses bluetooth to connect to the car’s OBD2 port. The program records and analyzes data from the car’s on-board computer. From there, a CleanDrive program that’s downloaded from the Apple app store reveals data such as acceleration, MPG, top speed and even a carbon score. The CleanDrive app will also display and reset the diagnostic codes sent by the car’s on-board computer.
