    Thank you so much for the explanation, I'll be trying this out tonight!

    Another question for the community:
    Following the wiring details in the preceding post, I've been able to get my rig up and running! Now I'm trying to tune in on the fine details, and I'm having some troubles.

    Essentially, it seems like the FFB response curve has a huge minimum threshold value, despite setting the minimum force to 0% everywhere I could. For example, driving in a straight line at speed, the wheel feels completely dead. It won't center itself, no road vibration, nothing. If I begin to weave side to side, as the weaving becomes more intense, suddenly the FFB will kick in quite strong and will feel really good through a corner. Then, the moment the car is settled again, the FFB just vanishes.

    Here's my build in a nutshell:
    Omron E6B2-CWZ1X Encoder, 1000ppr
    12v 180w 2000 rpm motor
    4.8:1 belt drive ratio
    BTS7960 43A motor driver
    12v 30A power supply

    I've done the lut generator, and here's an example of what it returns... quite different from my G27 files. upload_2023-3-21_21-43-39.png

    After adding it to AC, here's how it looks:

    Any help would be incredible, I'm so anxious to drive this wheel!

    How does it feel in the EMC software? I set my max ffb to 80% but minimum force before it moves is quite high too.

    Yeah that's almost exactly what I'm experiencing, it's like there's a huge dead spot when the forces go below a certain value. Almost as if the motor isn't responding unless there's at least 75% feedback force requested. I've tinkered with wiring and tried everything I can think of, not sure what to check next.

    Do it all from the EMC software. You have to get that right before anything in-game is going to work.

    Turn on desktop spring effect and bring up min force until it offers something reasonable.
