Got an iPhone and want 0-60, 1/4 mile, skidpad, braking Gs?

This is too cool for words if it works, and apparently from all the initial posts I have seen on it, it does:

iPhone Apps We Like: Dynolicious Car Performance Meter

I'm away from home and don't have access to the mustang, but I'm going to try this out immediately. Bummer that it's $12.99, but that beats $200+ for a similar piece of hardware to do this. They should win an award for the most innovative use of the accelerometer on the iPhone.

You don't need a 3G iPhone, the original works just fine, you just need the 2.0 software update. I can't really trust my speedo accuracy, so this is a great little application to get me my 0-60 as well as my 1/4 mile and regular street cornering Gs.

cool, wonder how accurate it is. I havent upgraded my iphone yet to the 2.0.

thats pretty sweet. someone is gonna have to use one while doing runs at the strip and compare their ET to waht the iphone gives..

Heh, I tested it out today finally - found a nice spot of flat, open road and let 'er rip. The results were pretty underwhelming, but accurate and seemed accurate for my car. I put in the following:

-3300 lb. vehicle weight, 3100 + me + soundproofing material which I figure is about 30 lbs. or so.
-Drivetrain loss of 18%, guesstimated for a TKO600 and a stick axle rear from what I've read around the web

Results: (best run)

0-10 1.13
0-20 2.24
0-30 3.32
0-40 5.19
0-50 7.39
0-60 9.9
0-70 13.61

max acceleration .79gs
Peak Horsepower 135hp. This is kind of what I would expect for a 100k mile 302-2v that started with 210hp at the crank and is bone stock. 18% drivetrain loss gives me a crank HP of 159, or about 25% loss in power over the years. It seems like the app pretty much does what it says. My runs were pretty consistent, and shifting sooner before I ran out of power did yield me my fastest run. Seems like it's well worth the $13 if you've already got the iPhone . . .

ok, some guys actually tested its' accuracy here. I think they are trashing the G-Tech a little too eagerly, which makes me question whether the video is some kind of ad, but see for yourself. Sobering realization: a Mini Cooper S with a cold air kit is 2.5 seconds faster in the 1/4 than my tired old 302 convertible . . .
