When using the built-in GPS data, I was getting perfectly smooth OBD data in the videos. I'm now seeing rapidly fluctuating data that doesn't seem right, both in the videos and in the data files.
Raw data: https://dl.dropboxusercontent.com/u/237 ... 404.hlptrl
As a workaround, I'm using https://gist.github.com/fredemmott/861f800299f694eaefb6 to make 1hz versions of the CSV file, and putting both the full version and 1hz version into RaceRender - and switching the noisy displays to use the 1hz version
I'm using a BT1 and an XGPS160
10hz GPS + GoPoint BT1A gives noisy OBD data

Using the internal GPS means that only a tens of the load needs to be processed. OBD is pretty sensible to system overloads and usually the first item that breaks. Which smartphone do you use?

iPhone 6 - and I'm not recording video on it so there's no encoding contributing to the load.

The 6 should be quick enough 
Have you checked for other - disturbing BT devices? What exactly is OBD showing? Is the connection dropping or is the update rate going up and down (a lot)?
