The iPhone has an app called Dynolicious.
Has anyone found a similar app for the Droid?
Here's a link to the app I'm talking about:http://www.bunsentech.com/projects/dynolicious/
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
# Other Speed Tests (0-10 MPH through 0-100 MPH in 10 MPH increments)
# 1/4 Mile Elapsed Time
# 1/4 Trap Speed
# Elapsed Time and Trap Speed for standard intervals (60′, 330′, 1/8 Mile, 1000′)
# Lateral G’s (current and peak)
# Braking G’s (current and peak)
# Horsepower (wheel and/or estimated crank)
# Friction Circle (max G’s in 16 directions)
# Downloadable Timed Run Graphs
# Downloadable Skidpad Graphs

I haven't found anything, but maybe someone else has better luck with keyword searching?
