Used the track apps lap timer feature on my darkhorse this weekend at the Ridge in Shelton, WA and ran personal bests by about 10 seconds which seemed impossible. Afterwards, I compared my stopwatch timer to the lap-timer in the track apps of the infotainment, and the timings were way off. when two minutes elapsed on my stopwatch, the DH timer was showing 1:49. I can see it being off by a tiny bit as reasonable, to be 10% off in an app that is specifically meant to be used to track lap times seems absurd. Not sure if software glitch or something else.
