I don't have an IPhone, but is it possible to upgrade to 5 to 10 hz on the GPS with an external one or did they block that to? I used the internal GPS on my Galaxy S2, the reading seems suspect at best.
I didn't watch it with the audio, but the apex speed looks okay except I believe the numbers are not 100% accurate. I see the data jumping every second as it updates. With that type of cornering speed, you should have a lot more straightline speed. I dont know what happened?
