Now, if you coded the car to show actual v= then theoretically it would be very accurate since I think it also pulls the data from the car's GPS. I could be just talking out of my ass. Mine is coded and there is a huge difference between the car's speedo and what it shows on v=. BMW speedos are very optimistic to say the least.
