Teamspeed.com - REV App Turns iPhone Into Performance Driving and OBDII Diagnostics Tool

YouTube - Rev: iPhone Motorsport of Tomorrow

Our friends over at Automoblog.com have taken the plunge and downloaded a rather interesting automotive application for the Apple iPhone called "Rev". The $40 (USD) app uses the iPhone's built-in accelerometer and GPS to provide a variety of data including instant and average fuel economy, acceleration, and commute times. Owners can either display this information instantly to get real time feedback or record it for later analysis.

While that's nice, Rev's real party piece is its advanced OBDII functionality. Accessed with the use of an aftermarket OBDII port connector, the Rev program offers sleek diagnostic tools and the ability to clear annoying "Check Engine" lights. Among the other features are real-time statistics concerning fuel pressure, throttle position, air intake temperatures, boost, and intake manifold pressure. Although certain features sound mind numbingly dull, the app does have its benefits so you might want to check out free "Lite" version to get a better understanding of its unique functions.
