Below is the general tuning for both American Truck Simulator (ATS) and European Truck Simulator 2 (ETS2). ATS and ETS2 have exactly the same telemetry outputs and share the same tuning.
Note: No Traction Loss and No Wheel Slip/Lock effects
There is no output of telemetry for Traction Loss or Wheel Slip/Lock by either ATS or ETS2. These effects have been disabled.
Note: Truck Names
Sim Racing Studio supports individual truck motion profiles for both ATS and ETS2. However, the correct truck name will not be displayed. Truck names will appear as either random numbers or names (ex. 00, 9, rails, them, etc). This is not a bug in SRS. These sims do not export the correct truck name with the telemetry output.
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 and Surge 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 by 60% to mitigate excessive movement. For example:
If no Sway actuators, reduce the Sway Effect Slider from 12 to 5.
If no Surge actuator, reduce the Long G Surge Accel/Decel Effect Slider from 11 to 4 for Accel and 9 to 4 for Decel.
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 profile have been tuned to a Spike Filter setting of 2200.
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.

American Truck Simulator and European Truck Simulator 2 General Tuning
Notes: Tuned utilizing telemetry from multiple trucks from multiple starting locations. This motion profile can be utilized for any truck in ATS/ETS2 as telemetry differences are extremely minor. Road telemetry gathered from speed bumps, curbs hits, off road, San Francisco hills, on and off ramps, drive ways, dirt roads, and many other types of terrain features. Note: Reduce speed when driving over speed bumps.
