For $12.99 on iTunes, you can purchase Dynolicious from BunsenTech, that will turn your iPhone into a performance meter. The software uses the accelerometer inside the iPhone lets you record 0-10 through 0-100 times, quarter mile and trap speed, lateral Gs, horsepower and more.
Full story here at Autoblog, and here at the BunsenTech site.
UPDATE: Here's another performance meter for the iPhone (or iPod) called g-tac--and it's cheaper than the Dynolicious, at $4.99!

They tested this software over at MyRide.com and found it to be accurate enough to be used in their car reviews. They did the first review using a Smart Fortwo convertible and the Dynolicious software on an iPhone 3G.

The review is very positive about the software.

That's pretty cool. I wonder if anyone has made software that uses the accelerometer on my shoe from my Nike-iPod+ ($29) that I use for running? :)
