Surprised that the case wasn't grounded tbh, considering logitechs never found out it might interfere with the sensor circuit. I connected mine on the pedal board connector underneath the board by unscrewing the board first (has lots of solder already there).Īluminum foil didn't make any difference, so I just removed it.Īlso do NOT connect it on the small board that comes with the motor, even if you figure out that the black cable actually is a ground!! Successfully connecting the greyish metallic case of the motor found just left of the steering wheel bar, with any ground, solves the problem Starion83 describes. Yeah this gentleman was absolutely right. This is my next step, should be interesting. Apparently one gentleman solved this by grounding the case of the motor and wrapping the motor case in aluminium-foil. This sort of makes sense, and matches the symptoms, as after further investigation it is only when the FF motor kicks in that the wheel loses calibration. Quote from Starion83 :One interesting theory I did read is the EMF caused by the force feedback motor brushes arcing on the spindle interferes with the optical sensor circuit. Still, its a step in the right direction.ĭigging an old thread here if anyone's still interested to fix their momo logitech wheel: My method of grounding the motor is not great however, i really need to solder the ground lead to the motor case, but my little 50W electrical soldering iron is not up to the task. Right, after grounding the motor case, and wrapping it in aluminium foil the effect is definately lessened, but not gone completely. Alas, this isnt a fix as i like my force-feedback to much. It cant be the optical sensor unit itself, as playing with the force feedback motor unplugged from the PCB causes the problem to vanish, so the optical sensor is working fine. I can get my center position back if i pause the race, turn the wheel lock to lock and continue playing, but its a little inconvenient to do that after every corner, and unfeasable for multiplayer play.
Not for the wheel losing calibration mid-play :/.

That particular patch you've linked to is for a different problem, its if you cant get your wheel's center position to line up to the game's center position to start with. I should mention that for the first 2 years of ownership the wheel was awesome, no problems whatsoever, this is a recent occurrance. This is my next step, should be interesting.Īnyway, apart from this last idea, can anyone please shed some light for me? Ive been hunting this inter-web thingee for the last 4 hours and have found alot of people complaining of the same symptoms, but no solid answers. One interesting theory I did read is the EMF caused by the force feedback motor brushes arcing on the spindle interferes with the optical sensor circuit. I've tried the MOMORACINGCenterFix that has been suggested, and it just stuffs up the signals, wheel does basically nothing, and pressing the pedals makes the wheel turn erratically in-game. I've tried the Logitech clear calibration utility, it tells me there is no calibration information to clear.
I marked it with some twink, played a bit to experience the problem, and checked its position relative to the motor spindle. Then I thought the gear on the back of the motor that runs the optical sensor disc *must* be slipping, even though it has no load on it to make it slip.
After a dissassemble and clean, still no dice! Problem is still there. Then i noticed that these beasties use an optical sensor to detect wheel motion, not a variable resistor, so i assumed it would just be dust causing the optical sensor to miss movements. Really, there is nothing to slip, as its all geared in there.

I assumed it would be something slipping inside, so i cracked it open and had a look.

This is not unique to LFS, happens in GTR2, GT Legends, The windows game controller calibration util etc. Basically any time you move the wheel fast, or fight the force feedback. For example, after turning a corner, the center position in the game no longer matches the center position of the wheel, i have to hold the wheel 30deg to the right to make the car drive straight, and after a few more corners, it might have slipped calibration back to normal, or maybe now i have to hold the wheel 60deg to the left to drive the car straight. My Momo Force (black) loses calibration while driving.
