SImucube SDL2, Direct Input, UE4 and Inconsistent results

Hello!

Im a part of a team that develops simulators.
We are currently using simucube for our steeringwheels and UE4 for simulations.

We are having issues using SDL2 and Direct Input to control our steeringwheel.
Constant forces works great, but for example “Spring” does not. it does create a spring effect, but it ignores the changes to for example “center”.

We are trying to get a steeringwheel to match up to a selfdriving car, and first thought that the easiest way would simply be by adding a Spring effect and changing the center position on tick, but that solution doesnt work since spring isnt working properly for us.

Our second solution is building a PID controller and using constant effects to push the steeringwheel towards the correct position, but that leaves us with a heap of other issues such as tuning, occilation etc.

Does anyone know wether Direct Input and SDL2 supports just setting the position of the steeringwheel and keeping it at that position (or any other position we choose at runtime).
