Thanks for the reply Tony! I actually just bought a kart from a member at OVRP like the OP and I’m not sure if the kart has the GPS module. I will check in a couple weeks when I’m back at the track.
Do you need the GPS in order to show the lap deltas?
I’ve searched the interwebs and people don’t seem to really be into the delta times but it seems that it could be really useful for practice or qualifying sessions to see if you are going faster thru a section. i.e. quick look at the mychron for a +/- delta from the previous lap.
