Alrighty, I should start off with what I have in my G.
09 x coupe 7at, with Stillen underdrive pulley and K&N drops ins, and an additional 40lbs of Dynamat. Half tank of gas, and me weighting 130lbs.

Motorweek did an review on the x coupe a while back and provided with some track numbers (YouTube - MotorWeek Road Test: 2009 Infiniti G37x), and here I got a Gtech, able to see how the x performs in everyday road conditions where there's gravel, wind, grease, rough pavement etc...

I only get the chance to test out 0-60 as I find it dangerous in doing 1/4 mile on public roads. Test was done under M mode (loaded to 2000rpm), as D is ~0.3 sec slower!!

Horsepower/Torque: It gives you an idea of what you're running, but can be effected greatly by road conditions, wind etc - aka useless

0-60: 5.54sec!

RPM & Shiftlights: Can't seem to get RPM calibration done; but oh well, no biggie, there's always the dashboard.

Handling Gs: It pretty fun looking at the number... to me it's not that important

So is it worth $220 USD w/ shipping?
Only if you plan to mod your car, and see how your G grows... other wise, let somebody get the numbers for you
I did get a chance to try out Dynolicious on the iphone, but can't seem to get it right, the numbers were at ~6.3sec which was pretty off.

FYI 08 FX35 20's 265's all around runs 7.8sec 0-60




(BB if you can help me with the pics again please)

 

Where you have the links tagged with "URL" simply change that to "IMG" to embed the images.

 

My Cobb does all that, plus it gives me an additional 22whp...

 

theres also a video on youtube where they compare the iphone app dynolicious and the gtech and the $13 app is more accurate.

woah, i should purchase this

 

I have the app. It does work very well.

 

its gotten good reviews...ill probably buy it in the near future.

BB, where/how do you mount the iphone?

 

I dont have any "secure" mounting for it. I have a Speck rubber skin on it and it fits almost perfectly in the cup holder. It doesn't move around so I roll with it that way.

 

the phone has to be tightly secured. If it moves around during launch, it will offset your results. Don't swear by the HP / TQ numbers either. Choose a flat road with no gravel, and warm you tires up!

 

what do you notice on your reading while in ds mode? you getting pretty much the same numbers in ds mode as you do going manual?

 

It doesnt move because it fits in there pretty tightly and the ribber case keeps it from moving. It was pretty darn close to my timeslip from the track.
