They make an adapter that plugs into the consult port so it can read off the ECU, which is only for nissans, so thats cool. They also make external sensors so I can run Oil-pressure sensor and a few other things if I want to. Its a pretty cool set up and I can do it for around 500$ not including the screen, but I'm going to get a double din head unit next month and it will plug into that.

I pretty much will have all the features of most new cars, Navi, DCC, digital read outs, Ipod interface blah blah blah. I'm venturing away from Race car and going more for GT car.
