So I got around to programming the SCII today for my 6.4 PSD. I thought that EOD, ECT, and TFT would be good things to know. Those all work perfectly. Then I ran across one that is called GEAR. I thought it might be interesting as when running down the highway to know what gear the truck was really in, like a downshift on a grade, etc.

The readout makes no sense at all to me. It is giving me numbers like 17, 18, 19. I have checked 3 times that I programmed it correctly, and can certainly do it again, BUT - has anyone here used that and can they tell me what those numbers mean?
