Here’s another issue I ran into once. I raced in the No Box Bonaza at Norwalk a few years ago and if you closely read the rules it says no data recorders. When I told him my RacePak dash was hooked to my data recorder it was needed to see my oil pressure, water temps, and other required info. He said I could not run the race. After some more calls I was told to remove the sd card and put a wire tie around it that could be inspected at any time. Gauges for me for now on.
