There is currently an OBD addon, I'm working on making it run a bit smoother before releasing it. It tends to be only partially reliable. The plan is to have a Gauge that you can put on any skin, or retrieve values via %variables% in skin files. Both of these are already implemented, just not used at the moment. If you want I can put up what I have and you can see if it works on your car. It also isn't very tolerant of hibernation.
Edit: what other thing?
