When does limp-mode kick in? 280? So Nissan evidently decided put the limp mode threshold at 20 degrees before the disintegration temp, probably as a bit of a buffer.

But I don't want any weakening of the bearings at all if it can be avoided. If there was a way we could set our own limp-mode threshold temps (like how we can adjust our shift light), I'd set mine at 255.
