you also have to have an iphone too...

even if this software is off by a few HP or miliseconds from a real drag strip/dyno. you still can use it for tracking changes between un-modded and modded runs of ur car.
kinda cool..


only $13..

 

very very cool. what does it work off of?

 

that's pretty tight, too bad i don't have an iphone....damn crackberries

 

The iPhone's built-in accelerometer.

You can always get this for less than the price of an iPhone. I like mine.

 

wonder if the iTouch has the same deal?

 

the itouch will have it also

 

I thought the new iPhone's were only $199 brand new though and that GTech pro is like $300...

 

correct, but the 199 is for the phone and a 2 year contract. to get the phone with out a contract is in the range of 600 or so

 

i was about to say, that makes sense now...

i was in best buy the other day and noticed an 8gb iTouch is like $299...at that time I didn't know the iPhone is $199 w/contact so I was stumped...thanks for clarifying that up

 

haha my friend just downloaded that...he paid 10 bux for it lol
were gna try it out someday

 

Take a vid

 

ya i will the next time i see him lol
but the phone has to be mounted somewhere stable to even use it....u cant put it in ur hand and start spinning it and expect for it to work lol
some people said it is pretty accurate. ill see about that
ill take vids and post it up

 

i have iphone but i dont have $12.99

 

Okay, so got my new iPhone, got the new SW (because let's face it, why wouldn't you? ), and tried it out tonight. Results are mixed:

The SW loads fast, and is pretty user-friendly. You put in the weight of the car (with you in it), expected drivetrain loss, and make/model/year. You also calibrate the accelerometer in the iPhone.

Can't really tell you how accurate it is, because I have nothing to compare it to; seems like it's within 10% or so though. On the last few tests, have no results - once the phone rang which shuts off the SW (doh!), and on the last two the iPhone barfed both times (even after rebooting) and tried to shut down - no reading.

Gave up at that point, but it's a fun toy.

Oh, and the max HP it estimated was 901 - that's good news

How about you and i get together one of these days and see how the app compares to the GTECH, at least it's some sort of comparison.

Btw, which track did you go to when you last took the G?
