Just Dyno'ed my ralliart using Dynolicious
Hi there all just wanted to share my experience with this iphone app I just tried. First let me explain how I did the test. The iphone was calibrated on a leveled table for better results. Since I don't have a iphone cradle for the car I just put it on the cup holder facing towards the front of the car and used a piece of cloth to isolate some vibrations. Now I pampered the car @ launch and all the shifts to reduce the vibration or sudden movements because I am not using a cradle. The 1/4 mile is slow but bare with me I lost time pampering the shifts. The car has only a INJEN intake, ported cyl head and RRM pulley, no Engine Management. Here are the plots notice the steady launch on the HP graph, the second one are the results emailed to me by the APP the car did 159 HP to the wheels (I had to input the car weigth and drivetrain loss).

Be sure to read the online instructions on how to mount it and calibrate it. IF you have any questions i can help u with it.
Just for the record I used 3100 lbs as the weigth and a 17% drivetrain loss.

A couple of comparisons,
This video really gives me confidence, I know it is not something you should rely on to tune the car but at least u have an approximate, there is also another app called REV which costs ~40$ and 150$ for a WIFI OBD2 connector that lets you datalog and DYno the car. I would definitively use that to dyno some friends car with a wideband using just the iphone to datalog and measure some WHP but again I will take it to the dyno later.

so just got back from trying this out, program worked well
screwed up the first time because i set off before the program said 'Ready'
this was the second run, pretty interesting results.
my car is an auto, completely stock, no performance mods at all

Go to the results tab then select you run, scroll down to the bottom and there you go... I believe the screen shot is a better approach but I wasn't home to get the screenshot from the iphone so I had to use the email.
