I've finally have had a chance to play around with the unit and really do like it. The instructions/"help" that come with it are not the greatest but the online forum is very helpful. It certainly the type of tool that you will want to play around with to detemine all its capabilities.
I was able to program a second fob, and verify that the EKA code I have is correct. It's very easy to check the fault codes (only a coolant level code, which was my doing).
