Throttle has a dead zone in the beggining

Hey guys,
I have been struggling a bit with the throttle values used in the topic /fsds/control_command.throttle in these last days. Firstly, I used the released version of FSDS v2.1.0 and when I sent a command lower than 0.278 in the throttle field the car would simply not move. When this threshhold was surpassed it would accelerate instantly reaching really high speeds.
I then decided to download UnrealEngine and change the Torque Curve in order to better fit an eletric car Torque curve. This indeed produced a change. The deadzone changed from 0-0.278 to 0-0.085. The behaviour after this is the same as before, the car accelerates abruptly acquiring really high speeds.
I wonder if anyone had the same problems. Any help is appreciated.
Cheers!
