I picked up an app for my Blackberry Storm called DynoStorm. It uses the accelerometer in the phone to measure acceleration and from that calculates 1/4 mile times and other metrics (G's, braking force, etc etc). It's $12.99 (it's also available for the iPhone for the same price via the iTunes App Store). I did a few runs and the times seem somewhat accurate...mph not so much. Here's my results:




Yeah the mph is definitely off there...lol I wish I could trap that high.



You can't see the 0-60 in the screen shots but it's around the 5.7-5.8 sec range. Has anyone else tried using this? Are you guys getting accurate results and mph? Tryin to get a feel for how it works for other people.

 

I know there are a few guys on here that have it. apparently its pretty close. i will be getting it when i get the 3Gs on June 19th

 

I got 5.4-5.5 0-60s consistently on my G-Tech, VDC off

 

Dynolicious also calculates HP.
Does this do that as well?

 

Since it told me I had 345 HP to the crank, I'm going to have to go with no. Maybe others have had more accurate results.

 

it may have to do with the accelerometer in the two phones, im sure they are both different.

 

I have a G-Timer which has always seemed pretty accurate - gave me 13.7s 1/4 mile on cool nights.

However, I have the FREE PocketDyno for my iPhone and although I've never done any 1/4 mile runs I've done 4 0-60 runs all with varying VDC, wheel-spin, etc. so just average them. I've gotten 5.26, 5.51, 5.8, and 5.91 0-60. I'd say its pretty accurate considering its free

 

I have a G-tech, but i haven't used it yet on the G.

 

I have this app for my iPhone, haven't used it yet in the G but it always got spot-on results for my RSX Type-S, very pleased.

 

where do you guys place your phone when you do the runs, is it in a cradle so it is standing vertically?

 

Yeah I have a cradle for mine.

 

I was under the impression that the iPhone had to be horizontal, but either way, I shove it in the crease of the passenger seat, won't move, soft on the phone:0)

 

I put mine in the storage compartment in the center console, it lays flat and against the wall so it doesn't move. You could put it in the cupholder laying flat sideways

 

wow how does it calculate HP?

 

I don't think such thing can calculate hp.
