Obviously you modify the case to allow the fans to suck a proper amount of air, and use some kind of cleanable mesh screen over the intakes to avoid the dust and contaminants.Fans are just increasing air flow to the inside of the case, and the g27 has only 2 tiny hoes on the top air flow will be very restricted. if the fan is sucking air out, or in, it's still bringing dust into the casing.
Isn't this the Force Feedback? In order for force feed back to work say when turning left , the left motor must apply force towards the right. In order for us to feel the feed back. So when we leave it to straighten out, it will simply just be the motors rotating back and fourth. All wheels do this.
Or just hold on to the wheel like everyone else in the world that the wheel works fine for. You wouldn't let go of a steering wheel of a car at speed on a track would you? On top of that, deadzones create innaccuracies and delays in input, making you less accurate and slower as a result.I have a Fanatec gt2 which emulates the G25/g27 wheel when in PS3 mode. It will oscillate just as the op is describing unless you set the deadzone on the wheel to 10%. Look for g27 hidden settings on the wheel itself to see if you can set a dead zone of 5 to 15% and it should be perfect.
