    Hello!
    I have asked earlier about surge movement but I have got it to work.
    Now my problem is sway. It kinda works like it should but after turning, it shoots the rig to the other direction.
    I have used several hours with settings and cant understand What is wrong with it.
    In assetto corsa every movement works like it should almost without any tuning.
    In Richard burns rally setting things up is really difficult.
    With my first seat mover rbr worked like it should without tuning.
    I have two ibt-2 and arduino Uno. 2 pieces of wheelchair motors.
    Earlier I had in seatmover 2 wiper motors and 1 monster moto.

    I have certainly seen this sort of thing particularly in F1 22 and 24. For RBR I am very satisfied with default settings. Of course heave, pitch and roll are the main consideration for RBR,

    I set up my defaults 20% for the five directions. That was a bit ugly. Then I ran the mini cooper in tuning mode on a “comfortable” track and saved the learned training data.

    The only issue I had was that on 100% imtensity for a car with 400hp it gets uncomfortable. So I run at about 70% intensity. I don’t have any filters set.

    Good luck. It’s a great game I am currently addicted to it.

    For sway, and similar axis, you should have same Min/Max values set:
