Looks good so far, now turn it up  >:D! It looks like you turned your centering feedback right off? Once you turn up the strength of the ffb you should be able to start bumping the centering back up until you find the sweet spot where it feels good without rattle.

As far as the buttons triggering when you plug in the amc you really need to carefully go over all your connections and make sure everything is properly connected to ground. The Happ motor/amc really has nothing to do with the buttons. The only way they are connected to the logitech is through the original motor outputs so there should be no reason any signal should be getting sent back to the logitech in anyway. I don't know where you mounted your logitech pcb but just to be safe maybe try moving it away from everything else by a few inches just to make sure there isn't any interference?

After I took this video, I tried adjusting it like you said too. I took the meter out, unplugged and plugged the wheel in. Measured with the wheel full lock left and right. One way the most I could get out of it was 23, the other way was like 19 something. After I did that I measured at the input and made sure it was at 0. After I did this, the wheel locked. I had centering and spring turned down to 12. Like you said, I couldnt feel much unless I ran into the wall or hit a car. I think Im going to try to hack the buttons like you did. What diodes do I use? I say the pinout that mark used, but Im lost lol.

If it's that far off you may have to take off the potentiometer on the wheel and adjust it a bit so it's closer to the stock center. If I remember correctly the calibration of the wheel potentiometer in windows doesn't have an effect on the force feedback center? I know it sounds stupid and it is but I remember that being the case for some reason. Basically what you will have to do is reinstall the pot on the back of the wheel, unplug the inputs from the amc and stick a voltmeter on the logitech motor outputs (not the amc outputs, but the ones from the logitech wheel). Try and get that as close to zero as possible, that way the amc won't have to offset such a large amount which will presumably cause issues. Once the outputs leaving the logitech read properly (should be close to 0 at center) then you can hook it back up to the amc and you will have to adjust the offset on the amc again.

Not sure if you saw this but its a short walkthrough about the buttons and has the diode part # I used.
