I had a thought and figured I should write it down somewhere. The Jaguar supports OBD-II, as demonstrated by my Scan Gauge II. It's a big ugly having the gauge sat on the centre console by the gear lever, even if it does tidy away neatly into the arm rest when not in use. I'm sure with a an optoisolator like the one going in to the Mazda dashboard, I could knock up an OBD-II reader out of a the Stellaris Launchpad I'm going to use to decode the radio UI. This means I could put real-time stats...
