I've been lightly playing with my Vette tune. Getting into trans settings and want to modify MPH shift speed points and shift pressures when I have the selector in sport mode, and also when using paddles. I notice in the tune that for shift speeds that I have Normal, Pattern A, Pattern B, and TUTD. I assume that Normal is for when selector is in D and TUTD is when I am using paddles. Which chart corresponds with when the selector is in "S"?
Next area is shift pressure. I have Pattern X, Y, and Z. Same question. I assume X is for "D mode". Which pattern is for "S mode"?? X? Y? Finally what is a safe amount to add to shift pressures? I have seen some tunes with as much as 60 psi added though entire chart. Is +10 to 20 psi a good place to start?
