Disable speed mode "Unlimited"

[Special]

I also assume that when you say "unthrottle key" you mean turbo or unlimited mode? Basically what the TAB button does currently. Personally I think stick buttons (L3, R3) are terrible to press, the less they are used the better, I think the best layout would be to have L2 stay the same but remove the Unlimited part to it, so have it do Standard > Fixed > Standard > Fixed, ect. when pressed, and change R2 to act as the TAB key does, as press & hold Unlimited or Turbo mode button.
