Hows it going audi-sporters? Downloaded the app virtual dyno today, now I dont expect it to give accurate results but wanted to compare runs before and after installing a bluefin map but im unsure about setting up the vehicle profile. Ive dont a bit of googling but so far no good. Does anyone have any idea what these values should be or where I can find the information myself? Tire diameter isnt a problem, frontal area im going to get a rough idea of the area from bottom of bumper to top of the windscreen. Done a Google of coefficient of drag and I dont know if this sort of info is available anywhere. I found out how to calculate it butbseems like a pita!
