Automobilista 2

Connection Method

Section titled “Connection Method”

Shared Memory — Automobilista 2 writes telemetry data to a shared memory region. You need to enable the correct shared memory mode in the game’s settings.

  • Shared Memory Name: $pcars2$
  • Update Rate: Up to 200 Hz

Setup Steps

Section titled “Setup Steps”
  1. Launch Automobilista 2.
  2. Go to Options > System.
  3. Under Shared Memory, select “Project CARS 2”.
  4. Apply the settings.
  5. In DR Sim Manager, select Automobilista 2 from the Source list and click Start Motion.

Available Telemetry

Section titled “Available Telemetry”

AMS2 provides one of the most feature-rich telemetry datasets:

  • Orientation: Pitch, Roll, Yaw (Euler angles)
  • Acceleration: Full 3-axis local acceleration
  • Velocity: Full 3-axis local velocity
  • Angular Velocity: Full 3-axis rotation rates
  • Speed: Vehicle speed
  • RPM: Engine RPM
  • Gear: Current gear (including reverse and neutral)
  • Suspension: 4-wheel suspension travel
  • Terrain Type: Surface type under each wheel (road, grass, gravel, rumble strips, dirt, sand, cobbles, snow, etc.)
  • Throttle, Brake, Clutch: Driver inputs (0.0–1.0)
  • ABS: Anti-lock braking status
  • Vehicle Name: Car name and class
  • Weather: Rain density, wind, temperature

Telemetry Quality: ★★★★★

Section titled “Telemetry Quality: ★★★★★”

AMS2’s shared memory provides comprehensive, high-frequency data at 200 Hz. The terrain type data is especially useful for the Ground Cue, which can generate surface-appropriate vibrations.

Section titled “Recommended Starting Settings”
  • Primary Cue Gain: 70–100%
  • Smoothing: Low to medium
  • Washout: Medium
  • Ground Cue: Enable this — AMS2’s terrain data allows the Ground Cue to produce surface-specific effects (rumble strips, grass, gravel)

Known Quirks

Section titled “Known Quirks”
  • Must select “Project CARS 2” mode: AMS2 supports multiple shared memory formats. Only the “Project CARS 2” option works with DR Sim Manager. If you see no data, check this setting first.
  • Same format as Project CARS 2: AMS2 uses the same shared memory structure as Project CARS 2. The Project CARS 2 source in DR Sim Manager also uses this format.
  • Sequence number validation: The shared memory includes a sequence counter that indicates when data is being written. DR Sim Manager uses acceleration changes to detect new data frames.
  • Rich terrain data: AMS2 reports over 50 different surface types, which DR Sim Manager maps to standardized categories (road, bumpy road, rumble strips, gravel, grass, sand, dirt, cobbles, snow/ice, concrete, metal).

Troubleshooting

Section titled “Troubleshooting”

No telemetry data

Section titled “No telemetry data”
  1. Go to Options > System in AMS2 and verify Shared Memory is set to “Project CARS 2”.
  2. Make sure you are in a driving session on track (not in menus).
  3. Restart both AMS2 and DR Sim Manager.

Shared Memory setting keeps resetting

Section titled “Shared Memory setting keeps resetting”
  • Some AMS2 updates may reset the Shared Memory option. Check this setting after game updates.
  • Make sure you click Apply after changing the setting.

Motion works but Ground Cue is inactive

Section titled “Motion works but Ground Cue is inactive”
  • Ensure the Ground Cue is enabled in your profile.
  • AMS2’s terrain data is only active while driving — it won’t show surface effects in menus or replays.
