This was definitely worth the $13 for an iphone app. In fact, it may be worth the cost of the iphone!

280 hp at the wheels using a weight guess of 3600 lbs. Assuming 15% for drive train losses, puts it at 327 hp at the crank. The S54 was rated at 333 hp. The 0 - 60 time was 6.7 sec with the traction control interfering off the start and through the middle of 1st and 2nd gear.

I've got it. its pretty sweet but finding a place to put it and keep it from moving is a pain. my best 0-60 is 5.2 on a cold night. my Hp was way off seeing I had me 250# and my buddy 160# and the weight was set at 3300#. there was a test in one of the car magazines and it was in most cases within a tenth of a second of all the high priced gadgets.

Yeah - the dirty little secret of accelerometers is that until you get really, really expensive, they're all basically the same -- the one in a G-Tech and the one in an iPhone are probably the same part.

Cool stuff!
