No problems at all, worked right out of the box. Yes i did install the enhanced param's for L67, You'll need that to scan for KR. The interface is a little overwhelming and takes a little time to get used to. Read that link I posted in detail, and then play with it. There more info then you'll ever need.
The thing I really like, is you can setup, go for a boot, and record your session tracking the paramaters you want to view. Then get back to your garage, sit down and watch it play back in real time. Much safer this way.
I rate it
