Question time. So here I am comparing between files SD shifting and the OBS shifting parameters and I came across TV maximum for the different shifts. The SD TV max for 1-2 is a whopping 40psi higher than the OBS, which was 47. SD max for 2-3 is over double, and 3-4 is 39 psi higher. Bumping up the indicated torque just slightly and using the TV slope and offset I'd be hitting the max fairly quick. Is there any reason I couldn't use the SD values for the maximums? Maybe the higher max was to allow for adaptive shifting, which I think I read could change up to 20 psi?
