  haha, maybe...
There's another one called FS-Pad, but none of these prototypes end up with a release:

My "proto with no release date":

Resurrecting the topic to show you an interesting gamepad that may have a built-in force feedback system on the sticks (and on triggers):

This gamepad looks interesting too, with the adaptive triggers AND sticks:

Adaptive triggers for the grip feedback (throttle and brake).

Adaptive stick for lean and wobble feedback (left/right), and for G force feedback (up/down).

What do you think about it?

Thank you DD, I appreciate the compliment...

   Yes the white parts are 3D printed. The support is glued on a steel sheet.

Waw! Crazy!
That's why I prefer the mechanical version...
Well, actually, the truth is I don't have enough skills in electronics !

Your simulator will probably cost 10000€ if you work with Keyence! 😂
I do not know if the weight applied to the pegs is a parameter, but it should be possible (but hard and complex) to compute the real pressure on pegs with other inputs, such as the torque on your rig, and send a single value to the simulation.

In my opinion it is a toy, not a simulator. It is just a seat on springs, which won't give a realistic feeling.
On the videos, you can see the rider leaning the bike left and right without moving his body, which is impossible in reality.
Also, the movement to get the bike straight up is very unrealistic.

DD,

I read both the steering and the lean angles that GP Bikes sends via UDP, using Processing. I calculate a servo position depending on both values and send it to an Arduino. I can adjust both sensibilities in real time to get a good feeling. I do not use the torque output. (I tried it with direct steering, it works, but I don't like it with a gamepad.)
On the previous videos, I was only using the steering angle, so I could only feel wobbling and grip loss. Now I can feel the weight of the bike too.
Of course, i have a single axis.
But the principle is the same: read 2 values, and send each one to 2 different servos.

Hope this helps...

very interesting,
Can you share some pictures of your system?

I've just tried with a rolling average of the received value and the results are similar to yours.
I tried with standard steering mode.
The damped value makes sense: I can see clearly that it pulses (up to around 200Nm) when I suddenly change direction.
It is quite stable when you ride quietly. 

For the dynamic tuning, prior to sending to Arduino, I use Processing so I can adjust in real-time the sent value using virtual buttons.
You're right about the joystick position, I hadn't thought about that yet...

Looks like we're on the good way.
Thank you for the help!

hmmm... if the steer torque value is less noisy when you decrease the FFB strength, I wonder if there's a way to reduce that noise when FFB is not active at all.
As I use a gamepad, I will not be able to enable FFB. Instead, I wanted to use the UDP data to generate the FFB.

At least, if the steer torque value is actually impacted by the FFB strength, then we are sure that we extracted the right info from the UDP message...

I (try to) use angle too.
so, apparently the "steer torque" output value cannot be modulated with the P/D settings...

hard to say...
I would say they are different equations, because FFB output is very different if you choose direct steer or normal mode.
But in both cases, the steertorque value is oscillating a lot.
Not sure I answer the question...

Trying to tune the P and D seems to be a good idea...

yes, I found that the steertorque value is unstable in both cases: standard gamepad with normal steering mode, or racing wheel with FFB and Direct steer mode.
