Pretty neat features but it appears to be inaccurate as hell, look at these times on the example they show:
There is no way in hell you can drie the 1/8 mile
14.5@98.2 or the 1/4 mile
14.5@120.3 lmao. You would have to be driving a beast of a car with zero traction.
The gtech RR is accurate though, I have compared mine while at the track and it was right on.
