    There is something that I don't understand : how we can parameter 3 forces with a 2 dof simulator with 2 axis ?
    Because for the moment I have Pitch and Roll at 30%, but when I try with surge, sway and heave, nothing moove even with virtual axis ...
    For the other forces in "Axis assignments" I had to add more DOF ?

    You first need to properly set the direction of the axis, you currently have roll going the same direction rather than one up and one down: https://www.xsimulator.net/community/faq/which-way-to-set-simtool-axis-movements.230/

    First set up surge, which uses the pitch axis, then sway, which is leaning the opposite direction to roll, then heave, which also uses the pitch axis. Do roll and then pitch last.

    As @insanegr already advised earlier, follow the steps here: https://www.xsimulator.net/community/faq/steps-to-create-a-motion-profile.228/

    Ok thanks :)
    I have try some parameters, and I continue to make test.
    I have alway some problems, my heave is very unstable he goes from -100 to 100 very fastly
    And wich parameter shoul I modify to have a better felt of the changing gear ?

    Think of Roll and Pitch as Track related, Not so much the car itself. Also Your testing a Somewhat Stiff Hyper car (looks like Mclaren P1) on a Super Flat Race track with no apparent hills anywhere....So thats part reason why you aren't feeling much.

    For roll and pitch there is no problem on a non flat road
    It's just for the other sensation, for the G force that are more difficult to configure
    Thanks for these information, I will continue my test and wait to have more material.
    I will also try to make a solidworks model of my playseat to have an idea of the necessary equipment.

    You cant expect to get any Sway when you dont have it even turned on in the Settings.....a FLAT race track will give VERY little Pitch or Roll data points.....Go to the Nords and test for Pitch and roll. You'll see what i mean.

    Yes thanks but I have understand and I have always configure the settings on the nordschleife circuit

    I Do NOT suggest using the nords as a Default testing ground. Yes it has lots of Pitch and Roll changes and a Great overall Mesh, but Far too much to base a default setup On. Spa would be a Far better Middle ground on
