# ---- Drivetrain (Gear Detection) ----
# When gear_ratios is provided, the dashboard calculates the current
# gear from RPM and vehicle speed. Without it, the ECU-reported gear
# is used (if available).
#
# To find your ratios:
#   1. Look up your transmission model (e.g., Tremec T56, Aisin AZ6)
#   2. Multiply each gear ratio × final_drive to get overall ratio
#   3. Measure or look up tire circumference (in meters)
#
# Formula:
#   expected_speed = (RPM × tire_circum_m × 60) / (gear_ratio × final_drive × 1000)
#   The dashboard compares actual speed vs expected_speed for each gear
#   and picks the closest match within gear_tolerance.
drivetrain:
  # Example: Mazda MX-5 (NC) 6-speed manual
  gear_ratios:
    - 3.636    # 1st
    - 2.375    # 2nd
    - 1.761    # 3rd
    - 1.346    # 4th
    - 1.062    # 5th
    - 0.843    # 6th
  final_drive: 3.909
  tire_circum_m: 1.95      # ~205/45R17
  gear_tolerance: 0.15     # 15% tolerance for matching

# ---- Vehicle Physics (HP Estimation) ----
# These values are used to estimate wheel horsepower from
# speed and acceleration using road-load physics:
#   HP = [(mass×accel) + (½×ρ×Cd×A×v²) + (Crr×mass×g)] × v / 745.7
vehicle:
  mass_kg: 1200            # Vehicle mass (kg) including driver
  drag_coeff: 0.32         # Aerodynamic drag coefficient (0.25-0.45 typical)
  frontal_area_m2: 2.2     # Frontal area (m²) — typical sedan ~2.0–2.5
  rolling_resist: 0.012    # Rolling resistance coefficient (0.005-0.02)

# ---- Data Logging ----

# ---- Server ----
