ADU 7 and AEM VDM

I’ve got an AEM VDM already installed in my car and I’ve replaced the AEM CD7 dash with an ADU7, which is now working fine. I’ve imported the VDM .dbc files and that all appears to be ok (the VDM is connected on CAN2 as it is 500kbps). How do I configure the lap timing and track mapping features to use the VDM channels?
