Here’s a cool new iPhone app called Dynolicious that will turn your iPhone into a real Dyno using iPhone’s already-capable accelerometer. This is definitely going to beat buying a stand-along Dyno or making an accelerometer yourself. 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! Some of the performance metrics Dynolicious can measure: 0-60 Acceleration 1/4 Mile Elapsed Time Lateral G’s Horsepower 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. via autoblog
