How do you save logs to laptop with cobb V3?

I have been using JB4 and had a cobb V2 for 18 months. Just bought a CobbV3



I have FBO and have installed RB's myself but cant use the ap yet.



I am getting PTF to tune my car but don't know how to log with it.



I can set the ap log parameters but where is it saved and how to i upload to laptop?



Cheers
