What are the drawbacks of ECU remapping for engines?

[LeKevin]

The drawbacks of ECU remapping for engines are: 1. It requires the use of higher-quality fuel, which increases driving costs; 2. If the ECU upgrade is not done properly, it can affect the engine's lifespan, cause the engine warning light to illuminate, and result in unbalanced power output; 3. Some vehicle models may experience excessive power after the upgrade, making the braking system inadequate, potentially leading to longer braking distances and safety concerns; 4. It may void the warranty. The function of an engine is: to convert the thermal energy of gasoline or diesel into mechanical energy by burning it in a sealed cylinder, causing the gas to expand and push the piston to perform work. The components of an engine include: 1. Valve train; 2. Crankshaft and connecting rod mechanism; 3. Ignition system; 4. Cooling system; 5. Lubrication system; 6. Starting system; 7. Fuel supply system.
