Iphone program that use car ODB connector

Hi,
I use dashboard+ from arc0baleno but I'm looking for something more precise that connects directly to the car ( ODB connector <> Iphone ) and analyze the raw data from the car cpu(speed,torque,rpm,..)..

Thanks in advance.

your car have to support it ,like BMW for example..
