We were running fairly low tire pressures by then, around 29-30 psi.
Very possible the M2C has different parameters, if so I am envious!

I think it must have a different setup. At the CCA O'fest my run group was about 15 cars, and after each run we returned off the course, drove a long way down a grid road, made a u-turn and then got back in line. I think I went four runs like that without shutting off the car. It would show 99% on the reset scale, but it never completed. I think it wanted to exceed some level of speed for a given amount of time, and that wasn't completed. The course was long and very fast in spots too (at the Michelin Proving Grounds, aka Black Lake).
Just recently when running at a CCA event at the PerfCenter, I let out a ton of air in the fronts to keep them at 34psi over the space of many runs. The course is very long (85 seconds) and very fast on their track, so the brakes get super hot as one would expect. Anyway, after a long cool down for lunch, the tires were around 28psi. I should have taken a picture of the display since it didn't say immediately inflate and throw a warning, but it did state something about checking the owner's manual and the tire pressures -- some sort of intermediate warning I guess when it sees all four tires near same level but not too crazy low? After a few runs (we all had many runs) and up to temp and pressure, that message just stayed on the screen. It didn't interfere with DSC off at all fortunately.
