Everyone has a certain method for getting their transmission tuned. I use the top speed setting at the bottom at the lowest because its how I learned how to. Im sure if you used 1 or 2 clicks higher on the top speed you would end up lowering the final gear more before you get to the point where youre going to set it for the final which would give you the same result but with higher gear numbers. After a lot of trial and error ive found that lower gear numbers for 1 - 3.
This is a list of my steps again but with pictures for each step as to show how its done.
This is just a base setup.
This is a BMW M Coupe with 460HP
This is how my method looks if done the way i typed out the steps:
1. set to default
2. lower top speed to lowest setting
3. set 6th to highest
4. lower final gear until you get desired top speed (140mph for this car)
5. select top speed and move it up one then back down to lowest
6. set final gear to lowest and remember new top speed (141mph for this one)
7. reset to default again
8. lower top speed to lowest setting
9. lower final gear to the remembered top speed (141mph)
10. select top speed and move it up one then back down to lowest
11. lower final gear to lowest setting
12. set 6th gear to highest (look, back to 140mph)
13. set 5th gear to highest
14. set 4th gear to highest
15. set 1st gear to lowest
16. make 3rd gear "pretty" (which means...line it up)
See no odd out of order lines. and I did the steps they way I typed them.
