BMW blue/green % curve

BMW history file content


The history file content numbers at the end determine the color shown on the graph or within the screen bottom line.

I've added those because I often find myself wondering if I used the phone or not while checking consumption. Hope you find those new features useful too!

Can you send me your history file? I will remove those for you, until I find a workaround for this. This will also help find the actual work-around.
