Is there a way to have the GTR cars with sequential gearboxswhile on the gas? when im in too high of a gear i have to get off the gas in order to downshift.
Its the way sequental gearbox with ignition cut works. To be able to shift, you have to unload the gearbox so it can change the gear. When you upshift, ignition cut does that for you, but under downshifting it is not used for logical reasons told in previous posts
Lifting is the only sensible option, you would never downshift with your right foot floored in real life and thankfully it is no longer necessary to do so in LFS to be competitive.
