Make your iPhone into a dyno
Ok this app took me about 3-4 tries to get used to it...I ended up needing to adjust the rollout settings as it was very sensitive and would start before I did anything. I got one good run in last night after 4 tries. Then went out again this morning and did 2 more...here are my results:
1st one:
60' 2.62 @ 26.7 mph
330' 6.71 @ 56.2
1/8 mile 10.03 @ 74.3
1000' 12.85 @ 86.4
1/4 mile 15.25 @ 94.7
0-60 6.93
Only 150whp
2nd one:
60' 2.65 @ 26.8 mph
330' 6.70 @ 56.8
1/8 mile 9.99 @ 75.8
1000' 12.79 @ 88.5
1/4 mile 15.18 @ 95.3
0-60 6.82
whp...only 150 again, but whatever I don't assume it to be perfect, I was using 2860 for my weight, and my fuel tank was nearly full...so that is close. Also 0% correction which is why I listed them a whp. I should be making at least 160-165whp and based on my trap speeds I would believe that I am...interesting tool none the less, and at $13 I can at least use it to compare changes in mods over the life of my car. Oh and yes, I suck at launching! BTW Clutch/LSD/Flywheel are not installed yet, they are going in tomorrow I just wanted to update my sig early. Only performance mods are
m7 16% pulley
JCW intake
Powerflex engine/gearbox bushings (if you really think they help)
TSW springs (if you think that changes the squat...)
215 series tires ~ 39psi
edit* also this was a nice flat road and each run is in the opposite direction to negate any slope/wind

The neat thing about the device is that it is using the actual acceleration of the car to get at the horsepower (Force = mass * acceleration; Work = force * distance; Power = work / time). So assuming the weight that you enter is correct, then in theory it should be giving you the actual power that you are putting to the ground to make the car accelerate. So, yeah, if you "suck at launching", it will let you know.

It looks like an even better app is going to be released in the app store. Rev light is kinda like dynolicious, but offers alot more in the unreleased full version. They are claiming with the correct hardware you can watch the car's stats in real time on your iphone.

Looks promising, if it works well i can't wait to buy

I can't even find one on the internet. It would have to act as a base station for the phone to connect to it, there website claims you can still use your edge or 3g connection for the internet while using it.
I'm a bit of a tech junkie so this looks like the perfect mod for my car. I already have a kuda mount on my center column so this will be sweet. The geek factor will be high.

That makes sense...yea a 2.6 sec 60' isn't exactly anything to be proud of. I also don't like to be particularly hard on the car at launch as I don't like the idea of all the force all of a sudden on all the components. I can only imagine that the LSD will really make the car rip away at the launch though..no more one wheel burnouts!
Just kidding. Seriously, 1st gear is broke and second isn't much better. The MINI just doesn't launch well unless you have REAL sticky tires. The LSD doesn't seem to help the straight line stuff too much.
Wait until you put a little more power on the car. Then you will suck at launching with two wheel burnouts.

, I sort of just let it happen to as I thought to myself "this isn't supposed to happen anymore"
Add another 60-80hp over what you have now and let me know if it gets any better. Bet my 60 ft time is slower than yours.

Rev is looking really interesting, this could make a low cost data acquisition system. I've been thinking I'd like something like this, but I couldn't figure out how you'd get the OBDII data into the iPhone, Apple doesn't let you at the dock connector from an ap.
I own an iPhone 3G. So yea, I've seen the price tag.
It is the monthly AT&T bills that get me, but my previous Verizon bills were just as bad, and that phone wasn't nearly as capable.

The iPhone will be fine, its more powerful than the desktop towers Apple was shipping 10 years ago, its pretty amazing what's in there. The biggest problem with the iPhone is battery power, you can't use all that computing power for very long without killing the battery in a hurry. In a car application you have access to power to plug into, so its less of a problem.

Rev communicates with a vehicle's ECU via its physical OBD-II port. Interfacing with this port requires an OBD-II wireless hardware device that supports the 802.11/WiFi interface on the iPhone and iPod touch.
so where can you find the OBD2-WiFi?
BTW, I bought the Dynolicious a couple weeks back for my iPod touch and love it/hate it. I love it for all it can do & show me, but I hate it b/c it's saying I'm only putting down 128 WHP....

This is too funny. I was actually talking to a friend who does iPhone app programming about making something like this.
The sticking point was all about getting the OBDII data into the phone to begin with, and I started looking for / looking at building an OBDII plug that would send the data via bluetooth; in a similar manner that Unichip's Flux option does to a pda.
It'll be interesting to see if this company gets the dock connection working. It definietly looks cool.

They're not using the dock connetion, they're using Wi-Fi. Apple doesn't let developers at the dock, even though there are UARTs in there which could probably do OBDII directly.
Btwyx is talking about *software* developers that are writing programs to run on the iPhone and iPod Touch. Those programs aren't allowed to access the dock port.
Denison and many other companies make *hardware* that connects to the dock port - things like chargers, external speakers, stereo interfaces, etcetera. Apple has no problem with that.

That's exactly right. Only Apple's built in firmware talks to the dock port. Anything attached has to conform to Apple's standards, and do something Apple is expecting it to do. They're not expecting an OBDII connection on the dock.
Ok, I'm going to open this one up again.
Dynolicious 2.0 via itunes store, gen 2 ipod touch.
Any issues with calibration, like it is not getting past step 2 and is taking a long time in step 1.
How long does calibration take you folks who have a working version prior to 2.0 dynolicious.
Thanks in advance, Don

1st gen touch, v2.2 software, v2.0 Dynolicious, no problems. As mentioned before, usually takes a second to calibrate in each position.
Have you tried turning off you iPod, turning on, then going straight to Dynolicious and calibrating?
Oh, BTW, has anyone looked at the REV software yet? Datalogging, and a bunch of other stuff via a wireless OBD2 port. I talked to Dynolicious about offering the same things and they're looking into it
