Understanding Your Data

Telemetry Channels

Telemetry channels are the individual data streams recorded during each lap. Each channel captures a specific measurement at high frequency, building a complete picture of what the car was doing at every point on the track.

For guidance on interpreting these channels, see Reading Telemetry.

Core Driving

Channel Unit Typical Range What It Tells You
Speed km/h 50–350 Car velocity. The shape of the speed trace through corners reveals your driving technique
Throttle 0–100% 0–100 Throttle pedal position. Shows how progressively you apply power on exit
Brake 0–100% 0–100 Brake pedal pressure. The shape of the brake trace reveals your braking style
Steering -1.0 to 1.0 varies Steering wheel angle. Smooth traces indicate consistent, confident driving
Gear -1 to 8 1–8 Current gear. -1 = reverse, 0 = neutral
Engine RPM rpm 3,000–15,000 Engine speed. Useful for shift point analysis
DRS 0/1 DRS flap state (F1 only). 1 = open
Clutch 0–100 Clutch position. Relevant for race starts

G-Forces & Rotation

Channel Unit Typical Range What It Tells You
Lateral G g -5 to 5 Cornering force. Higher values = more grip being used
Longitudinal G g -5 to 5 Braking/acceleration force. Negative = braking
Vertical G g 0.5–2.0 Vertical load changes from bumps and elevation
Yaw rad Car rotation around vertical axis
Pitch rad Forward/backward tilt (braking pitches forward)
Roll rad Side-to-side tilt during cornering
Front wheels angle rad Actual front wheel steer angle

Position & Motion

Channel Unit Typical Range What It Tells You
World Position X/Y/Z m varies 3D car position on track. Used for track maps and racing line visualization
World Velocity X/Y/Z m/s varies Speed in each world direction
Local Velocity X/Y/Z m/s varies Speed relative to the car (X = lateral, Z = forward)
Lap Distance m 0 to track length Distance from start/finish line. The X-axis for most charts
Session Time s Elapsed session time

Tires (per wheel: FL, FR, RL, RR)

Channel Unit Typical Range What It Tells You
Surface Temperature °C 70–120 Outer tire temperature. Most responsive to driving style
Inner Temperature °C 80–110 Tire carcass temperature. Changes slowly, indicates core heat
Tire Pressure PSI 20–28 Inflation pressure. Rises with temperature during a stint
Tire Wear % 0–100 Remaining tire life. Track across a stint for degradation rate
Tire Damage % 0–100 Damage from lockups, curbs, or contact

Brakes (per wheel: FL, FR, RL, RR)

Channel Unit Typical Range What It Tells You
Brake Temperature °C 200–1100 Brake disc temperature. Overheating reduces braking performance
Brake Damage % 0–100 Brake wear from sustained use
Brake Bias % 50–65 Front brake proportion. Higher = more stable under braking

Fuel & ERS

Channel Unit Typical Range What It Tells You
Fuel in Tank kg 0–110 Current fuel load
Fuel Remaining Laps laps Estimated laps at current consumption rate
ERS Store Energy MJ 0–4 Current battery charge. Full = 4 MJ in F1
ERS Deploy Mode enum 0–3 Deployment aggressiveness. Higher = more power
ERS Deployed/Harvested MJ Energy used and recovered this lap

Suspension & Dynamics (per wheel where noted)

Channel Unit Typical Range What It Tells You
Suspension Position mm -20 to 20 Suspension travel per wheel. Shows weight transfer
Wheel Speed m/s varies Individual wheel speed. Differences indicate slip
Wheel Slip Ratio -0.2 to 0.2 How much the tire is slipping longitudinally (braking/acceleration)
Wheel Slip Angle rad Lateral tire slip. The foundation of cornering grip
Ride Height (front/rear) m 0.02–0.10 Ground clearance. Drops under braking (front), rises under acceleration

Data Frequency

Telemetry is captured at the game's native output rate (typically 60 Hz) and compressed for storage:

  • High tier (20 Hz) — Core driving inputs, position, velocity, g-forces
  • Medium tier (5 Hz) — Temperatures, pressures, wear, ERS, suspension
  • Low tier (1 Hz) — Settings, damage, compound, flags

Higher-tier channels give finer detail for fast-changing values like throttle and brake, while slower-changing values like tire wear only need infrequent sampling.
