Hello!

Would anyone know the name of program, where you could modify the revs and gears of the car.
It was working with an old version of LFS... (Y i think?)

thanks, Zan

I don't think there was an official version of Tweak Y, so chances are it's a rare find. Tweak Z though is pretty good though. You can't adjust the RPM, but you can change the number of gears.
