Im trying to comfigure the transmission on my corvette zr1rm 09 by following drag tune up, but they say like 1.399 in 2th gear and i can only go down as 1500, my final gear and top gear are corect
The people who are telling him the ratios are probably using flipped transmissions. Which will give a whole new set of numbers or put them out of range than a non flipped trans.
Best to use a good base tune, they're in the sticky's, (in the drag racing forum !) Then you'll have a base trans that has a flip and possibly get to the ratios the others are telling him.
