Tuning Guide
Optimize your vehicle's performance with engine tuning, suspension setup, and transmission adjustments.
Engine Tuning
| Parameter | Effect | Tips |
|---|---|---|
| Compression Ratio | Higher = more power, but requires higher octane fuel | Increase for performance builds |
| Ignition Timing | Optimizes combustion efficiency and power output | Fine-tune for maximum torque |
| Fuel Injection | Adjusts air-fuel ratio for optimal combustion | Leaner = more power, richer = safer |
| Turbo Boost | Increases intake air pressure for more power | Balance boost with engine durability |
Suspension Tuning
| Parameter | Effect | Tips |
|---|---|---|
| Shock Absorber Stiffness | Stiffer = better cornering, softer = more comfort | Stiff for track, soft for street |
| Spring Rate | Controls ride height and handling response | Lower springs improve aerodynamics |
| Stabilizer Bar | Reduces body roll during cornering | Increase for tighter handling |
| Wheel Alignment | Adjusts tire contact patch and steering | Negative 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
| Parameter | Effect | Tips |
|---|---|---|
| Gear Ratios | Shorter ratios = faster acceleration, longer = better fuel economy | Short ratios for drag racing |
| Differential Ratio | Final drive ratio affects overall acceleration | Match to engine power band |
| Clutch Setup | Stiffer clutch handles more power but is harder to modulate | Upgrade for high-power builds |
