My 14 is doing the same thing under normal riding; Hard to fine issue with no codes. I assume bad gauge,ccu or wire harness grounding; If someone figures this out chime in.
Gauge is resetting while you are riding. When restarted it cycles the needle and lights up the LCD completely.
I used to have this problem with my original gauge. My thoughts are that since at least 3 people have had the problem it likely is a software bug. A lot of people probably miss it too.
My original gauge ended up being left on a trailer and flying off while going 65mph on 694, so I wasn't able to tell if it would randomly reset after my reflash, but I've never observed a reflashed gauge reset itself like that either.
I can tell you though that if I had a bug during development of the reflash, the classic reaction is to reset the MCU because of an illegal op code, which is the equivlent of a blue screen on a PC.
