Do you have to do a full lap on Route X? Like if you're tuning for 1/4 mile you have to go all the way around or can you end early and still get the times?
You choose the test you want to run and it ends right after that. So the 1/4 mile would end and give results right after the 1/4 mile is up. I think even the top speed run is only run on the straight and then it ends before the 1st corner.
