To be honest I never ended up using the laptime feature on my RacePak it was just too complicated for me to figure out! I use the RaceChrono app on my smartphone instead. It is just way easier.

Cool seats by the way! Although I am surprised why you didn't go with a halo style seat to offer extra protection especially since you have a cage? Also I would recommend to install a sturdy back brace to your driver seat that ties to the horizontal bar right behind it. Makes the seating position soo much stiffer!
