DiRT Rally 2.0 / PT Actuator - Thanos

Below are the motion profiles for DiRT Rally 2.0 which are categorized by the base horsepower for the vehicle. Utilize a tuning based on the horsepower output of the vehicle. The horsepower for each vehicle is listed in DiRT Rally 2.0 on the vehicle selection screen. If an exception is listed below, utilize the recommended tuning. For a General Tuning for DiRT Rally 2.0, utilize the 275 to 350 hp tuning.

General Tuning for DiRT Rally 2.0

Utilize this tuning as a General Tuning for DiRT Rally 2.0 as it's Max Telemetries are in the middle between low and high horsepower vehicles if you do not want to use different horsepower specific profiles.

Motion Profiles by Vehicle Horse Power:

• 100 to 150 hp: Examples: H1 (FWD) Lancia Fulvia HF

• 150 to 275 hp: Examples: H2 (RWD) Alpine Renault A110 1600 S, H2 (FWD) Peugeot 205 GTI, H2 (RWD) Ford Escort Mk II

• 275 to 350 hp: Examples: R5 Ford Fiesta R5, R5 Peugeot 208 R5 T16, NR4/R4 Subaru WRX STI NR4, H3 (RWD) Renault 5 Turbo, Up to 2000cc Subaru Impreza (2001), Group A Subaru Impreza 1995, Group A Mitsubishi Lancer Evolution VI

• 350 to 500 hp: Examples: Group B Lancia Delta S4, Rally GT Chevrolet Camaro GT4-R, and Crosskart Speedcar Xtrem

• 500+ hp: Example: RX Supercars 2019 Ford Fiesta Rallycross (Mk8)

Exceptions:

General Tuning for DiRT Rally 2.0 - utilize the 275 to 350hp tuning.

Crosskart Speedcar Xtrem (120hp) - utilize the 350 to 500hp tuning.

Platform Tuning

This motion profile was created on a PT Actuator 6DOF Simracing Platform (150mm: 7 Actuators (2 Front + 2 Rear + 2 TL + Surge). Since all motion platforms can be slightly different, please use the guidance below or utilize the quick tuning guide here for quick adjustments or the full guide here for detailed tuning information.

4 Vertical Actuator Tuning

Sway, Surge, and Traction Loss is converted into pitch or roll for platforms that do not have horizontal actuators. Since these motion profiles were created on a platform with horizontal actuators, the tuning(s) could result in excessive pitch or roll on platforms without horizontal actuators. IMPORTANT: For an axis that does not have a dedicated horizontal actuator, it might be necessary to reduce the Effect Slider for Lat G Sway, Long G Surge Accel and Long G Surge Decel, or Traction Loss by 60% to mitigate excessive movement. For example:

• If no Sway actuators, reduce the Sway Effect Slider from 14 to 6.

• If no Surge actuator, reduce the Long G Surge Accel/Decel Effect Slider from 16 to 6.

• If no Traction Loss actuator, reduce the Traction Loss Effect Slider from 18 to 7.

MDBOX Tuning

Due to built in smoothing effects for MDBOX, it may be necessary to reduce the Effect Smoothing by 50%. Surge, Sway, and Traction Loss may require Effect Smoothing to be removed completely.

Actuator Size and Mounting

These motion profiles were created on a platform with 150mm actuators with the Front to Rear Vertical Actuator spacing at 1290mm and the Left to Right Vertical Actuator spacing at 745mm. Actuators placed closer together or are larger than 150mm will increase the angle of pitch and roll. To mitigate the increase of motion if needed, reduce the Effect Slider for the impacted effects or reduce the Max Angle.

Max Angle

These motion profiles have balanced to allow for the increase of Max Angle and Max Horizontal to 100 (unless noted otherwise). This will allow for the maximum movement capabilities of the vertical actuators. However, if less motion is desired, reduction of the Max Angle will reduce overall motion while still retaining the balanced effects.

Reverse Surge

These motion profiles were created with the surge actuator reversed. This will cause the platform to move forward when accelerating and backwards when decelerating. To reverse the surge actuator, please follow the tutorial here.

Spike Filter

The motion profiles have been tuned to a Spike Filter setting of 3600. If more feeling is desired when landing from jumps, increase the Spike Filter to 4500; however, any crashes or driving errors will be extremely jarring. IMPORTANT: If you have downloaded the motion profile from the SRS Cloud Share, it will utilize your default Spike Filter settings. If you do not increase it as indicated in the motion profile, your Spike Filter may engage often and motion will feel muted.

Multiple Tunings for DiRT Rally 2.0

Unfortunately, DiRT Rally 2.0 does not export the name of the vehicles in telemetry. This makes it impossible for SimRacingStudio to automatically load different tunings for different vehicles. However, utilizing the ability for SRS to import/export tunings, a user can create multiple tunings for DiRT Rally 2.0 by following the process outlined here.
