About this app

**Tuning Tools** brings together essential calculators for anyone who works on engines, fuel injection, and vehicle tuning. All in one app, with a simple interface and results you can copy or share.

**Engine**
• Displacement — volume displaced by the engine
• Compression ratio — compression ratio
• Engine R/L — stroke/bore ratio
• Dynamic compression — effective compression during operation
• Mean piston speed (MPS) — in m/s
• Mean effective pressure (MEP) — ​​Mean Effective Pressure

**Injection and Fuel**
• Power per injector — estimated maximum power from injector flow rate
• Injectors per power — injector size required for desired power
• Pump flow rate — fuel pump capacity
• Lambda percentage — correction to achieve target Lambda (Ethanol, Methanol, Gasoline)
• Fuel change — percentage change in the injection map when changing fuel (includes mixtures with nitromethane)
• Fuel calculator — consumption and range

**Performance and Assembly**
• Weight/power ratio — in kg/hp or kg/kW • Gear ratio — reduction and final speed (with tire dimensions)

• Weight distribution — front vs. rear percentage

• Distance calculator — time and speed

**App Features**
• Light and dark theme
• Automatically saved values ​​— when reopening the app or calculator, the latest data appears
• Share results — copy or send the result via other apps

Ideal for enthusiasts, mechanics, and tuners who need quick calculations on a daily basis, without intrusive ads and focused on practical use.
