Straight steering problem with Logitech Momo

[Stanny]

Hi all,

I am experiencing a strange straight steering problem with my brand new Logitech Momo Racing Force Feedback wheel.

Whenever I drive straight with accelerator pedal down to full throttle at certain point my car (Audi RS4 750 BHP) starts a slight turn by itself while wheel is being hold in straight position. In the result I get a huge spin out at a high speed.

I have done nearly everything, changed the steering sensivity for different values both in Shift profile of Wingman profiler and in-game presets, as well as steering, acceleration, braking deadzones, adjusted force feedback strength from maximum to minimum values.

Nothing helps and that odd effect can be noticed best after the first turn in Spa circuit, I just can't go that straight with accelerator pedal down as the car starts steering itself.

Any help and possible solutions will be greatly appreciated. Thanks.

Sounds frustrating. On one hand it does sound odd, like a glitch or bug... but on the other it sounds somewhat reasonable that your 750BHP beast might be responding naturally and cannot maintain traction. I might be way off, but are any of these options possible?:

- Are you accelerating hard and the back wheels losing traction? Hmm, wait, RS4 is 4wd so a bit unlikely.
- Have you gone over a small bump and car becomes weightless, losing traction?
- Is the car lacking downforce at high speed? Therefore losing traction?
- Have you gone for mainly BHP upgrades and not handling upgrades? eg, suspension, tyres.

Does this problem happen with any other cars? or games?

Is force feedback actually working? This might sound really stupid, but you do have the wheel plugged into the mains and not just into the computer, don't you? Otherwise you can get the exact problem you describe.

Yes I have the wheel plugged in (Left light on) and Force feedback is working (wheel centers itself when cockpit loads, shakes and bumps depending on car movement). But nevertheless I cannot drive normally after the first corner of Spa - pushing accelerator all the way down and holding wheel straight, the front wheels start detracting to the right or left (depending on the certain place of my racing path) and I get a 180 degree spin out while trying to counter this.

I must notice that I do not experience any steering lag. In general, the wheel feels somewhat of extremely sensitive, down to slightest movements or even shakes of my hands. This Audi is tuned to the max with all available Tier 2 suspensions and bodykits, it's steering lock is set to 49, changing it down does not help much.

And what sharikov is saying maybe right, but i'm sure the light on the right is indeed the FFB light.

Maybe the centerspring or reversFFB not set.

This vid (http://www.youtube.com/watch?v=sVBqKiMduIs)of a momo wheel appears to show both lights illuminated...?

Also, 49 sounds like a large steering lock for the momo which has 270degrees lock - this probably explains why the "wheel feels somewhat of extremely sensitive, down to slightest movements or even shakes of my hands".

I have all the effects that are displayed on this video. The problem is that they do not respond to the strength adjustments (Specific game settings, Global device settings). They are either terribly stiff and strong (so FFB motor basically takes all the control of my car - drives or spins the car itself) or very weak and barely felt. I have to apply enormous power trying to steer the car with 100 percent of FFB and centering spin effects (like driving the car without any signs of power steering). And if FFB effects kick in - they just beat the car out of my hands.

I think there is something wrong with Logitech drivers (those from stock CD) and I will be trying to do a complete reinstall to a newest version.

[matt2380]

Latest version (http://www.logitech.com/index.cfm/441/320&cl=us,en?section=downloads&WT.ac=sc|downloads||dd)is 5.08 :)

Enable centering spring but set its strength to 0%.

Yes both lights have to be turned ON.

Stanny, you can try these settings to see if they help. Make a backup of your default controller config file you are using (i.e. vehicleset_pc_logitech_g25_separatepedals.xml) and then try these changes:

I'm using the following (for a G25 but you should be able to so something similar for the Momo):

Many thanks guys, managed to resolve the problem by upgrading to the latest drivers as well as doing some wheel sensivity adjustments. Anyway I have to learn driving once more now. :-)

here is my custom wheel config for Momo - Feels good to me!

Thanks rmi :thumbup:
