Joystick curves

Hi folks, got myself a t16000 joystick and il2 for Christmas..... Il2 has been torture. Found nuclear option and a much better experience. However my joystick/me very twitchy. No option for curves setting IE low response for small movements near the middle of the stick to aid targeting then higher motion when you move it. Do you guys have curves setup on your joystick or is it just a case of getting better?
