Got iPhone?
Get Dynolicious.
From Autoblog:
One app that has us really psyched is a new automotive performance meter called Dynolicious from BunsenTech. It uses the accelerometer inside the iPhone to let you record 0-10 through 0-100 times, quarter mile and trap speed, Lateral Gs, horsepower and more. Results are also displayed in real-time on the phone itself with graphs and a speedometer. You can also configure the tool with updates to your car, weight, before and after performance measurements, and keep a complete history of all your runs. The kicker is that you don’t even have to plug in your iPhone anywhere, just set it in the cup holder and drive.
Sounds fascinating. But how does it work? Must be a GPS thing, right?
For $13 at the app store, it’s got to be worth a look.
