We recommend that you always start with default settings in the game and in your wheel’s software, including overall force feedback gain and rotation angle. For example, on PC you can run 540 degrees of rotation in software, but the steering lock in-game will remain unchanged, so your ratio would differ from the default. You can also adjust this in the game's Steering Sensitivity slider in the Advanced Wheel Settings section below. This is a commonly misunderstood setting, so it’s important to give this a read.
Normal vs Simulation Steering
Having the option to choose between “Normal” or “Simulation” steering in the assists menu is one of the reasons so many players of different skill levels can enjoy Forza games, whether using a gamepad or a wheel. Forza is known for being controllable and natural on a gamepad, and these systems are a major component of that feeling.
There are multiple systems layered together to create Normal steering. Some of these layers alter inputs where some of these layers alter the vehicle dynamics. Simulation Steering turns these systems off. The input layers of these systems are turned off any time you use a wheel, regardless of the steering setting.
The Normal steering assist may make FFB feel “sharper” because it influences the yaw inertia of the car to help maintain control during rapid lock-to-lock steering situations. This makes the car somewhat less agile than with Simulation steering, but also more stable.
Advanced Wheel Settings
Below are the tunable settings for wheel users. We strongly recommend starting with default settings to get a feel for how your wheel works with the game, then tune for a specific desired outcome, one setting at a time. If you start moving multiple sliders without understanding the effects of each, or how they interact with each other, you may be creating an undesirable experience.
STEERING AXIS DEADZONE INSIDE
This sets the size of the inner deadzone for steering. The larger this deadzone, the more the steering wheel will need to be moved before the car begins to turn. This acts in the center of steering. Usually, any value other than zero will cause a dead area in the center of the wheel travel. Only turn this up if you have trouble traveling in a straight line.
STEERING AXIS DEADZONE OUTSIDE
This sets the size of the outer deadzone for steering. The larger this deadzone, the less the outside steering wheel input will be recognized by the game.
STEERING AXIS INVERT
This reverses the direction you need to move the input axis to steer.
INVERT FORCE FEEDBACK
This reverses the direction of your force feedback. Used for some wheel manufacturers. If your wheel pulls in the direction you’re turning instead of resisting movement, toggle this value.
ACCELERATION AXIS DEADZONE INSIDE
This sets the size of the inner deadzone for throttle. The larger this deadzone, the more the throttle will need to be pressed before the car begins to accelerate. Turn this up if throttle input is registered in-game when the controller throttle is in a neutral position.
ACCELERATION AXIS DEADZONE OUTSIDE
This sets the size of the outer deadzone for throttle. The larger this deadzone, the less the throttle will need to be pressed for the car to accelerate as fast as possible.
ACCELERATION AXIS INVERT
This reverses the direction you need to move the input axis to accelerate.
DECELERATION AXIS DEADZONE INSIDE
This sets the size of the inner deadzone for brakes. The larger this deadzone, the more the brakes will need to be pressed before the car begins to slow. Turn this up if brake input is registered when the controller brake pedal is in a neutral position.
DECELERATION AXIS DEADZONE OUTSIDE
This sets the size of the outer deadzone for brakes. The larger this deadzone, the less the brakes need to be pressed for the car to brake as sharply as possible.
DECELERATION AXIS INVERT
This reverses the direction you need to move the input axis to decelerate.
CLUTCH AXIS DEADZONE INSIDE
This sets the size of the inner deadzone for clutch. The larger this deadzone, the more the clutch will need to be pressed before the car’s clutch will begin to disengage. Turn this up if clutch input is registered when the controller clutch is in a neutral position.
CLUTCH AXIS DEADZONE OUTSIDE
This sets the size of the outer deadzone for clutch. The larger this deadzone, the less the clutch will need to be pressed for the car’s clutch to be fully disengaged.
CLUTCH AXIS INVERT
This reverses the direction you need to move the input axis to use the clutch.
HANDBRAKE AXIS DEADZONE INSIDE
This sets the size of the inner deadzone for handbrake. The larger this deadzone, the more the handbrake input will need to be actuated before the car’s handbrake will begin to apply. Turn this up if handbrake input is registered when the controller handbrake is in a neutral position.
HANDBRAKE AXIS DEADZONE OUTSIDE
This sets the size of the outer deadzone for handbrake. The larger this deadzone, the less handbrake input will be recognized by the game. Turn this down of the game registers full handbrake before the input is fully pressed.
HANDBRAKE AXIS INVERT
This reverses the direction you need to move the input axis to use the handbrake.
VIBRATION SCALE
This sets the vibration intensity. In Forza Horizon vibration is used as a tactile sensation to let you know what is happening with the car. You will feel a vibration when you’re overusing the tires or having a collision. Turning down the vibration scale will not change the road feel. Road feel is a physical force coming from load changes on the tire.
FORCE FEEDBACK SCALE
This sets the level of overall Force Feedback strength on your steering wheel. This changes all forces which are sent to the wheel including the spring and damper. Adjust this value carefully as it is possible to saturate forces and cause your wheel to clip. This does not scale the vibration.
Individual cars will have higher and lower steer torque capabilities depending on their suspension geometry, mass, downforce and cornering forces. The default Force Feedback Scale is set to a neutral value which generally shouldn’t clip. Players can increase force but risk losing fidelity in higher torque situations.
CENTER SPRING SCALE
This sets the Dynamic Centering Force of your steering wheel. Larger values provide a stronger centering force while lower values provide a lighter centering force. Lowering this value too much may cause steering oscillation. Too high a value reduces the dynamic align torque you feel from the car’s tires.
Essentially, the spring is the force pulling the steering wheel toward center; that is to say gravity through caster, KPI and scrub radius (the distance in front view between a car’s king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road). This force is overcome when at speed and while experiencing cornering load through pneumatic and mechanical trail (the align torques that a tire creates as it rolls along, which tends to steer it). To ensure full feel of align torque, the center spring is dynamic, ramping down with cornering load, slip and speed. The faster you go or the harder you push the tires, the less center spring force you should feel, and the more you feel from the tires steering themselves.
TIP: We recommend that you NOT turn Center Spring Scale up significantly – too high, and this effectively cancels dynamic FFB – the only force you feel is your wheel trying to center itself, rather than the dynamic align torque from the car’s wheels. We recommend you leave it alone or turn it down.
WHEEL DAMPER SCALE
This scales resistance to the movement of your steering wheel. Larger values provide a heavy feeling while lower values give a light feeling with little to no resistance. The damper is dynamic and reduces as the tires slip to preserve detail. Lowering this value too much may cause steering oscillation. Raising it too much may overpower oversteer or understeer feeling.
Damper is specific to the wheel the user owns and is very subjective. Effectively, it adds a resistance force to the steering that may prevent oscillation but at the same time it slows down the steering wheel velocity, making drifting, where you need quick reaction from the steering wheel, more difficult. Many wheel users think that the damper is wrong no matter what it is set to, because it is not coming from the alignment physics; in reality every car’s steering has a mechanical friction component slowing movement. The frictional forces and thus damper are dynamic, allowing a stable feeling without a constant resistance to movement.
TIP: Wheels with more torque, such as direct drive wheels, benefit from some damper scale; wheels with less built-in torque, such as the Logitech G920 and G29, often require little to no damper scale. If you have a Logitech G920 or G29 steering wheel, you may want to turn both the Wheel Damper and Center Spring down to get more feel from the tire.
MECHANICAL TRAIL SCALE
This scales the mechanical trail – the length of the static lever arm from the suspension geometry. Sometimes referred to as ‘caster feel’, raising this tends to give a smoother, faster force but with less fidelity.
Mechanical trail tends to turn the wheels in the direction of travel and thus is a smoother stronger following force with less tire slip feel. This is excellent for drifters but does tend to overpower feelings like lockup and understeer.
FORCE FEEDBACK MINIMUM FORCE
This scales the pneumatic trail – the length of the dynamic lever arm from the moving tire contact patch. Scaling this down will reduce the dynamic effects from tire deformation.
Pneumatic Trail comes from the deformation of the tire caused by the loads imparted on it. It decreases as the tire slips, which allows you to feel the onset of understeer or brake lockup. As it rises and falls through the range of tire slip, it can be a peaky force which results in sharp sensation at the edge of traction.
ROAD FEED SCALE
This scales higher frequency load inputs which come from the road surface and bumps.
As this is a full physical system, road feel comes from the individual wheel loads, just the same as the force feedback. To allow adjustability, Road Feel Scale amplifies the higher frequency loads while leaving the low frequency loads alone. This allows you to turn up or down curbs and other rough surfaces without affecting aligning torque.
LOAD SENSTITIVITY
Similar to Road Feel, Load Sensitivity scales the medium frequency forces in align torque that come from road elevation, oscillations and bounces. Lowering it can create a smoother experience at a cost of fidelity.
STEERING SENSITIVITY
This adjusts the ratio of your steering wheel’s degree of rotation (DOR) to the car's front wheels’ actual degree of steering rotation with a soft lock. Along with Force Feedback Scale, this is one of the most commonly misunderstood advanced settings.
A point of confusion among wheel users is the fact that the driver’s hand animations in cockpit view don’t turn the steering wheel more than 540 degrees in either direction. This does not represent the actual in-game steering wheel rotation. This is one of the reasons a dashboard camera view has been added to game camera views.
Altering Steering Sensitivity completely alters the input/output map of the steering, effectively changing the steering ratio of the car. The most common issue is when a user changes the steering wheel rotation degree from the software or hardware in combination with the game, which can result in erratic car steering behavior. Steering ratio defines the ratio between the steering wheel rotation and the turn of the wheels. In other words, how many degrees of steering wheel turn are required to turn the car’s wheels by 1 degree. A steering ratio for a normal passenger car could, for example, be 13:1, which means that 13 degrees of steering rotation are required to turn the wheels by 1 degree.
On PC, the wheel driver controls the steering wheel's degree of rotation (180 up to 1080 depending on the wheel hardware), but in-game and in real life, the steering lock is fixed on every car and is different on every car. Steering Sensitivity scales the steering input and alters how much the wheels are turned for a certain steering wheel rotation. If you make the sensitivity higher, you make the steering more responsive because the steering ratio has decreased. If you set the sensitivity lower, the steering ratio increases therefore the steering is less responsive. It is suggested to alter this setting only with your wheel software or hardware if possible, and to only adjust the in-game setting if your wheel does not provide its own option to adjust rotation.
STEERING LINEARITY
This adjusts the mapping curve between physical steering input and in-game steering. Lower values provide more accuracy near the center, but less accuracy near full lock. Higher values provide more accuracy near full lock but less accuracy near the center. 50 is a linear mapping.
In either case, the full rotation of the wheel and the steered wheels will be reached.
