WSC70 Mod

RealFeel ReadMe for V1.0

The chassis files for these cars are built to model the chassis of the originals. The combination of chassis layout, steering alignment and choice of tyre play a big part in determing how the car feels and what sort of feedback you get.

The cars in WSC70 cover a wide range of layouts and the weights range from 615 kg with the engine at the back to nearly 1400kg with a 7 litre V8 in the nose. This produces a wide range and quality of forces back through a force-feedback wheel. The cars work quite well with RealFeel and the personality of the car comes back to the driver as feedback.

Steering arm location determines the sign of MaxForceAtSteeringRack. The GT classes have steering ars behind the front axle, so MaxForceAtSteeringRack is positive, whereas the other classes, being rear-engined sports cars, have the steering arms in front of the axle and MaxForceAtSteeringRack is negative.

Unfortunately there are limitations in the hardware available for driving sims. If force-feedback wheels could emulate the actual forces involved in driving a racing car then there would be a few smashed desks and bruised wrists in driving-sim land. But they do not, so we must adjust the maximum force as it is read by RealFeel if we want to reduce clipping and improve the fidelity of the feedback. However, those settings do dumb down the differences in feel between cars. If you want to experience the differences, set MaxForceAtSteeringRack=-2200.000000 for all the classes.

RealFeel is set by class of car in WSC70 and the settings for each class are -

[Sports 2000]
MaxForceAtSteeringRack=-2200.000000
SteeringDamper=11500.000000
FFBMixerRealFeelPercent=100.000000
SmoothingLevel=0

[Grand Touring 2000]
MaxForceAtSteeringRack=2800.000000
SteeringDamper=11500.000000
FFBMixerRealFeelPercent=100.000000
SmoothingLevel=0

[Grand Touring 5000]
MaxForceAtSteeringRack=5500.000000
SteeringDamper=11500.000000
FFBMixerRealFeelPercent=100.000000
SmoothingLevel=0

[Prototype 3000]
MaxForceAtSteeringRack=-2000.000000
SteeringDamper=11500.000000
FFBMixerRealFeelPercent=100.000000
SmoothingLevel=0

[Sports 5000]
MaxForceAtSteeringRack=-2500.000000
SteeringDamper=11500.000000
FFBMixerRealFeelPercent=100.000000
SmoothingLevel=0

These settings replace all the settings used by the cars prviously released in HPM and should be used as starting points for wheels such as the G25 and DFP but please feel free to change them as you see fit. If you have a Black Momo or similar 270° wheel, you might try setting SmoothingLevel at 2.

I hope you enjoy these cars as much as I do.
