The Apple iPhone has taken the world by storm since it first launched in 2007. Its huge following means that developers are constantly developing new applications to take advantage of the phones technologies. One such application for us car enthusiasts is called “Rev“.

The US$40 application 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.

However, Rev’s real party trick is its advanced OBDII functionality. Accessed with the use of an aftermarket OBDII port cable or wireless adaptor, the Rev program offers sleek diagnostic tools and the ability to clear annoying diagnostic messages and warning 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. Fortunately there is a “Lite” version available free, which you can download to get a better understanding of its unique functions. Alternatively you could try a similar application called Dynolicious.

Dynolicious is a feature packed application that uses the internal accelerometers incorporated in the iPhone and iPod Touch to track your vehicles performance.

Just some of the performance metrics Dynolicious can measure are:

* 0-60 Acceleration
* 1/4 Mile Elapsed Time
* Lateral G’s
* Horsepower

The slick interface and low price of only $12.99 downloaded from iTunes makes it an interesting tool to any enthusiast. Read on to see what the developers have to say.

Dynolicious is the first automotive performance meter available for the iPhone and iPod Touch. Dynolicious uses the hardware built-in to your iPhone to measure the performance characteristics of your vehicle. No external wires or equipment is necessary, simply slip the iPhone into a cradle or cupholder and go!

Unlike other accelerometer-based performance meters, Dynolicious uses the advanced data-handling and display capabilities of the iPhone to make the most of your performance testing. Dynolicious maintains a history of test runs, showing you averages and trends in your results. Dynolicious also allows you to enter modifications performed to your vehicle, and will instantly show before-and-after results to easily identify gains or losses.
