Tuning Guide

Optimize your vehicle's performance with engine tuning, suspension setup, and transmission adjustments.

Engine Tuning

ParameterEffectTips
Compression RatioHigher = more power, but requires higher octane fuelIncrease for performance builds
Ignition TimingOptimizes combustion efficiency and power outputFine-tune for maximum torque
Fuel InjectionAdjusts air-fuel ratio for optimal combustionLeaner = more power, richer = safer
Turbo BoostIncreases intake air pressure for more powerBalance boost with engine durability

Suspension Tuning

ParameterEffectTips
Shock Absorber StiffnessStiffer = better cornering, softer = more comfortStiff for track, soft for street
Spring RateControls ride height and handling responseLower springs improve aerodynamics
Stabilizer BarReduces body roll during corneringIncrease for tighter handling
Wheel AlignmentAdjusts tire contact patch and steeringNegative camber for corner grip

Tire Tuning

Tire Pressure

Lower pressure increases contact patch for better grip. Higher pressure reduces rolling resistance for fuel economy.

Tire Width

Wider tires provide more grip but increase drag. Choose based on intended use — wide for racing, narrow for daily driving.

Tread Pattern

Performance tires have minimal tread for maximum grip. All-season tires offer better wet weather performance.

Transmission Tuning

ParameterEffectTips
Gear RatiosShorter ratios = faster acceleration, longer = better fuel economyShort ratios for drag racing
Differential RatioFinal drive ratio affects overall accelerationMatch to engine power band
Clutch SetupStiffer clutch handles more power but is harder to modulateUpgrade for high-power builds
