Nice mod! I play alot with dozers and this make the control so much better. With some track vehicle I can turn simply by pushing the joystick like excavator but with some other mods like dozer I still need to push the throttle. I guess this have to do with the treshold you mentionned?
No, the threshold is just for the steering axis so you don't need to have the steering wheel perfectly centered to not engage the idle turning for example (and still have the deadzone at zero for smooth steering in the center).
Which dozer do you mean? Then I can take a look into it. Idle turning should work without throttle.
I ran some tests: the game's original excavator can be turned with the joystick without accelerator needed. With the CAT 349 excavator or the D11 bulldozer from FS Miner, I still need to use the accelerator to turn in addition to the joystick. Nevertheless, driving dozers is much smoother with your mod enabled.
