    I need your collective help.
    I have been fighting this problem for a couple months now and am certain it is a configuration issue...
    ONLY in PCars 2 and Dirt Rally (Not in AC EVER) Using the exact same JRK settings (Obviously) I will be driving up or down a steep hill (Pitch) or steep banks (Roll) and my sim will go to the extreme extents, sometimes even opposite of the intended input actually. Until the input event has decreased below what ever value that stops it (I don't know) Anyone ever seen this? I have included screenshots of both Rally and PCars 2 as well as my axis setup and JRK settings.
    Odd thing is it does not happen every single time in the same turns or hills. I assume I am just taking a slightly different line causing this. But why is my machine jumping to extreme limits. It actually hurts as it is a very abrupt input (Running 25:1 PSaw) Kills the experience as well!

    In Dirt Rally currently, I cannot get enough (IMO) pitch because I have to turn "UP" the value in the tuning center just to keep the pitch axis from jerking to its extreme. I currently have it set to "8" in pitch, and it does not have much range of motion but also does not jump tp its extreme. As soon as I turn up the pitch to "9" the jerking almost completely goes away, but I do not have very much pitch movement at all then...

    Hey Brett, one of your motors has an absolute minimum greater than the minimum. Intentional?

    yeah, I have been playing with those settings..... hummm....
    Not saying that isn't it partially, but both motors go to extreme limits as described above...

    Since I had to change one of the JRK's a few months back (actually sorta when it started lol) I guess it would be advantageous to completely go through setup again...

    So Zed, I think you got it... I went through the JRK setup process from scratch, and all the numbers lined up much better now, Mins and Max Mins are correct. Been driving for about a hour and so far zero issues as before.
    Hope it continues!

    Did you reset the JRKs to their default factory setting and then do the setup from scratch?

    The option to reset to default is in the Pololu menu.

    It just happened in PCars2 in the 69 camero, going over a steep hill at the same time I stomp on the gas and when (Surge) was added the rig went to full "back" position for about 3 seconds until I got down the hill

    Hey Brett, not sure but I’ve had a similar issue in PC2. It’s not quite the same but your comment about the 3 seconds makes me mention it. For me it’s sway. I can’t run with sway in PC2 or else I have places in the tracks where my sim kicks over to the side and stays there for about three seconds then straightens up. It’s dead repeatable for me and doesn’t matter how fast I transition where it happens. I’ve inched through and when I hit the point, hard kick. At Indy it’s even on a straight. It also doesn’t seem to happen on every track. If I take sway out of the forces, it doesn’t happen. I don’t have any explanation but it could be I have something not set right. Also, where I had wind at first, it quit working in PC2. No idea if related. But other than no wind, as long as no sway, no problem whatsoever.

    I haven’t added filtering yet. You running with any filtering?

    Forgot to mention, AC works perfect for me too. Wind, sway, etc. But I also see the sway effect in No Limits 2 but wind works there as well.

    That sounds like it is game generated, perhaps there are a few bugs loose.

    Yeah, I was afraid of it being game related. But for me it does not always happen. On nordsleife, through the first carasel, it happens in roll 1 in 10 times, then not again the entire race....

    Norbeast, Is there a good step by step setup for the entire JRK process by chance?
    Still would not hurt to go through it again I think.
