Performance & Sound

Performance Stages

Config.StageStress = {
    Enabled = true,
    TickMs = 1000,
    MinRPM = 0.45,
    MinThrottle = 0.65,
    MinEngineHealth = 350.0
}

Stress only applies while the engine is under high throttle/high RPM.

Stage	Requirements	Behavior
Stage 0	Stock vehicle	No extra power, sound gain, handling, or stress.
Stage 1	ECU	Mild street tune, improved throttle response.
Stage 2	ECU + Downpipe	Strong road tune, more power, louder output, moderate stress.
Stage 3	ECU + ALS + Turbo + Downpipe	Aggressive tune, stronger ALS, louder output, higher mechanical stress.

Each stage can change torque/power/volume multipliers, pop burst bonus, ALS intensity and scale, default 2-Step RPM, handling multipliers, fuel drain, heat gain, and engine wear.

Effects (shared/config/effects.lua)

Pops & Bangs (Config.Pops): RPM range, minimum speed, lift-off inertia delay, burst count/interval/cooldown, volume, pitch, flame scale, and louder-bang chance/multipliers. Default activation uses normalized RPM 0.65–0.95 at a minimum speed of 60 km/h.

Shift Bang (Config.Shift): the extra pop/valve sound after an upshift: enabled state, minimum RPM, pop/valve volume, delay, probability.

2-Step (Config.TwoStep): the stationary limiter: default/min/max RPM, low/high RPM cut delays, volume, flame scale.

Launch Control (Config.LaunchControl): default/min/max launch RPM, volume, flame scale, and the wheelspin threshold used by launch effects.

Valet Mode

Config.ValetMode = {
    MaxSpeed = 50.0 / 3.6
}

Anti-Lag (Config.AntiLag): minimum RPM, activation key (default G), burst interval, intensity, flame scale, and whether ALS ignores pop inertia.

Ambient Sounds (Config.Ambient): continuous mechanical audio: Gear Whine, Mechanical Coast, Waste Gate.

Sound Presets (shared/sounds.lua)

Config.Volume = {
    Master = 0.1,
    Pops = 0.2,
    Limiter = 0.2,
    TurboValve = 0.1,
    DumpValve = 0.1,
    WasteGate = 0.1,
    GearWhine = 0.1,
    MechanicalCoast = 0.1
}

Config.DefaultPreset = 'car_01'

Preset	Notes
car_01	Default: low/rally pop and limiter sounds plus dump valve, wastegate, gear whine, and mechanical coast.
car_02	Alternative exhaust, limiter, dump valve, and turbo valve set.
car_03	High/rally focused exhaust sounds with fallback turbo/gear sound behavior.

Intensity-based presets can use LOW, RALLY, or HI, with thresholds set in Config.IntensityThresholds.
