    yes :cheers!! got it working very nice now with zero errors on the one motor and 16 on the other after about 15mins of dirt rally which is got to be quite hard on the motors with all the jumps etc.
    only thing that it lacks is the feeling of brake force I guess I will keep playing with the profile thanks

    however just got off Assetto Corsa and wow the feeling of braking is awesome :cheers

    regards

    Awesome! What motor settings did you use?

    In Dirt Rally, try lowering the "Surge" values in the tuning centre or go in to the games profile and turn up the Surge slider.

    On mine I still get a few errors, About the same as you get now. It is sort a balancing act between too much or too little duty cycles.

    I am happy with a few errors now and then, you usually can't feel them if they are that infrequent.

    Hi @Avenga76
    Got max duty cycle = 400
    Max acceleration = 500
    And brake duration 20ms

    Seems to have done the trick and the motion seems great more than happy with it (you are right about not feeling the errors) so cheers for the motor settings and I will do some tests with surge tomorrow need sleep lol it's like 2:30 in the morning over here lol

    Regards

    Cool. Yeah, from my testing I think the brake duration is what fixes it. It just give the motors a little bit of time to slow down before changing direction.

    Yeah, I have racing the Lotus 98T at Nords. With motion and the Accuforce it is quite a workout.

    That looks really good.

    You should try adding a racing harness. It stops you "Floating" around so much in the seat. Made a huge difference on my rig.

    Have a look at 0:58
    you'll notice that your head and body is always vertical and the seat is moving without you...
    I suggest you to use a harness and you will appreciate much more from your simulator! :cool:

    My temporary harness connection to the frame is a couple of bungee cords.

    @noorbeast heave is set at 20% and 0.6 max and min in the tuning center

    heave is set the lowest of all the DOFS when I tested it on its own it seamed ok
    happy to accept advise and do some testing (always happy to test)

    one question thou what are you seeing or not seeing in the video to question the heave setting ? keen to learn what to look for ;)

    cheers
