i think what you might mean is something like the the torque app you down load to your phone. you still need to plug in a wifi dongle to the obd11 port. there are plenty of other apps available which may be better. a lot of people use scan gauges. im not sure how usefull they would be on a y62. don't they already have something that gives you fuel usage and such. PS; pop over to the introductions thread and say hi, you might get better response to your post.
