Harry's Laptimer has a library of tracks - worldwide. Super easy to use, the only glitch I haven't been able to fix is a small delta between screen events and audio. OBD II dongle gives the rest of the car data. I also use racebox mini for super accurate GPS position data, and thus timing data.
if I buy the app is the track pre-loaded (area27)?… , is all the data shown there from the OBD reader?
