Want to turn your iPhone into a performance driving and OBDII diagnostic tool? Well now you can. The app uses the iPhone’s built in GPS and accelerometer to provide a variety of data, including instant average fuel economy (readers with Ferrari’s and Lamborghini’s obviously you don’t care about this, so pay attention), acceleration, and commute times. Owners can either display this info instantly to get real time feedback or record it for later analysis.
While all this is “cool”, Rev’s real knock out punch, is its advanced OBDII (On Boards Diagnostic System) functionality. With the help of an aftermarket OBDII port connector, the Rev program offers sleek diagnostic tools and the ability to clear that annoying “Check Engine” lights. Among the other features are real-time statistics concerning fuel pressure, throttle position, air intake temp, boost and intake manifold pressure. All for $40.
