In what is starting to look like a bad call, I recently aquired a set of dials from a -03 156. I was hoping to use these in a project of mine but I didn't stop to think about the CAN-bus integration. Does anyone have any pointers on DIY CAN-bus systems? I've heard mention of Motec and Skynam but haven't had the time to look them up yet. Any good? Value for money? What other brands are there? Also, I need/desire to have the odometer reset to zero but that is looking difficult as well. Thoughts?
