Working out the "Perfect" FFB settings for Logitechs
« on: August 04, 2007, 03:40:41 am »
As posted by Shawn in the Technical Support forum.  (I thought it should be here in addition to the TS board)

"So having now got my DFP(VERY good wheel highly recomend it) I have gotten a handle on the FFB settings for this game and have learned a few tricks from the "Wheel Guru's" on how to get the most out your MOMO or DFP(maybe even the Wingmans can benefit from these it just involves a simple number change.

okay FIRST your Control panel setting should look like this:

Now of course unless you have a DFP the rotation will be different but thats not important other than adjusting your Wheel Lock on the cars.
The reason for the overall effects strength being so high is that at 100% or better the effects are again more linear to the game(so make your FFB adjustments in the game rather than here)

The wheel lock on the cars is important to get linear steering travel so for example anything over 270 degrees of rotation  to get real linear steering you would need a full 34.5 of wheel lock and on a tighter track say 27.5. DO NOT use Speed Sensitive Steering its TERRIBLE and not for wheels more for Gamepads and Joysticks, using it will only dull the steerings rotation and make it unpredictable

the Sensitivity in the games Controller section should be set to 50% for ALL axiis(Steering, Throttle , Brakes)This will get the steering moving completely linear to your inputs, the Deadzones are your preference(I am running 0 on the wheel and 25% on the Throttle and Brake.

NOW here are the .plr file tweaks that make the BIG difference
This is the FFB section in your plr file I wll highlight the changes in bold and explain their effects at the end(well as best I can anyway)

FFB Device Type="4" // Type of FFB controller: 0=none 1=wheel, 2=stick/custom, 3=rumble pad. If you have a Wingman set this to 1
FFB Effects Level="4" // Number of FFB effects to use: 0=No Effects, 1=Low, 2=Medium, 3=High, 4=Full, 5=Custom.
FFB Gain="1.00000" // Strength of Force Feedback effects.  Range 0.0 to 1.0.
FFB Throttle FX on steer axis="1" // 0 = Throttle effects on throttle axis, 1 = throttle effects on steering axis.
FFB Brake FX on steer axis="1" // 0 = Brake effects on brake axis, 1 = brake effects on steering axis.
FFB steer vibe freq mult="0.50000" // Controls frequency of steering vibration. Recommended: 0.5 to 1.0, 0.0 disables steering vibration.
FFB steer vibe zero magnitude="0.03500" // Magnitude of steering vibration at 0mph (reference point).
FFB steer vibe slope="0.00000" // Slope of line defining magnitude as a function of frequency (used with FFB steer vibe zero magnitude).
FFB steer vibe wave type="0" // Type of wave to use for vibe: 0=Sine, 1=Square, 2=Triangle, 3=Sawtooth up, 4=Sawtooth down.
FFB steer force average weight="0.90000" // How much weight is given to new steering force calculations each frame (0.01 - 1.0). Lower values will smooth out the steering force, but will also add latency.
FFB steer force exponent="0.75000" // Steering force output "sensitivity".  Range 0.0 to infinity.  0.0 to 1.0 = higher sensitivity, greater than 1.0 = lower sensitivity.
FFB steer force input max="-11500.00000" // Recommended: 11500 (-11500 if controller pulls in the wrong direction).
FFB steer force output max="2.00000" // Maximum force output of steering force, recommendation 0.8 to 2.0 Will increase steerin weighting off center
FFB steer force grip weight="0.4000" // Range 0.0 to 1.0, recommended: 0.4 to 0.9.  How much weight is given to tire grip when calculating steering force.This is the real key to this, this setting affects the FFB when it understeers and makes the wheel go VERY light 0.4 will prevent this unless under extreme understeer
FFB steer force grip factor="0.6000" // Range 0.0 to 1.0, recommended: 0.2 to 0.6.  How much of a factor the front wheel grip is on the steering weight.
FFB steer update thresh="0.0001500000" // Amount of change required to update steer force/vibe (0.0 - 1.0). Lower values = steering force updated more frequently = lower frame rate.
FFB steer friction coefficient="0.00000" // Coefficient to use for steering friction.  Range: -1.0 to 1.0
FFB steer friction saturation="0.00000" // Saturation value to use for steering friction.  Range: 0 - 1.0
FFB steer damper coefficient="0.00000" // Coefficient to use for steering damper.  Range: -1.0 to 1.0  Setting these all to 0 will give the steering  MUCH better weighting
FFB steer damper saturation="0.00000" // Saturation value to use for steering damper.  Range: 0 - 1.0

Now this is all I have for now but basically this will give your FFB a more realistic feel and better weighting just remember to adjust your Wheel Lock in the cars to give yourself  linear travel and if you decide the FFB is to strong adjust in the game NOT in the control panel setting

If anyone has any questions or problems just ask me and I can easily explain better or walk you thru the changes"
