Cell phone dyno. apps.
Anyone ever use a blue-tooth cell phone dyno? I downloaded one the other day but don't have the adapter. I was wondering if they are worth a crap.

Re: Cell phone dyno. apps.
Phones like the Iphone which have built in inertia sensors have apps like a dyno. There's nothing to plug into the car. You just mount the phone on the dash. You need to enter basic information such as total weight etc. You then make a 1/4 mile run and it can calculate how much HP it took to run a 1/4 mile. Since it detects your exact position, it will know exactly how far a 1/4 mile is and exactly how fast you were going at the 1/4 mile.
On a dragstrip, the mph will usually be lower because it's a calculated number. 66 feet before the finish line is a MPH light. The time it takes to break that light then the finish line light tells the timing system how many feet per second you were going and gives a MPH.
I've never seen or have no idea how an app loaded with bluetooth has any application to being used as a dyno unless the phone has inertia sensors. There was a program a few years ago that ran off a palm pilot and used a timing light inductive clamp as a pickup sensor. It was accurate enough for most people.

Don't want to thread jack but if there are any app geeks out there looking to make a little $$$, I would definately pay for an iphone datalogger for ODBI.

My app. is for OBDII cars, hence it won't work on my '88 but thinking about trying it on my '99.
