# Automobilista 2

## 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

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**.

> **Important**: You must select "Project CARS 2" as the shared memory mode — not "Project CARS" or any other option. AMS2 uses the pCARS2 shared memory format.

## 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: ★★★★★

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.

## 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

* **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

### 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

* 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

* 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.
