What are the effects of stage 1 ECU tuning on a car?

[Josh]

Stage 1 ECU tuning has the following effects on a car: After ECU tuning, the vehicle will require higher quality gasoline. Using low-quality gasoline may damage the vehicle. It also increases temperature requirements. Here's additional information: Warranty voidance: After ECU tuning, the engine operates at overclocked frequencies, which may affect engine lifespan without an excellent cooling system. Dealerships may refuse warranty claims. Vehicles with modified ECUs may be denied warranty coverage by dealerships. Principle of ECU tuning: A car engine's operation is controlled by the vehicle's computer (ECU). The ECU regulates intake air volume, fuel injection quantity, ignition timing, etc., thereby determining engine efficiency, power, and torque. The database recording corresponding parameters like intake air volume, fuel injection quantity, and ignition timing under various operating conditions (RPM, gear, load, temperature) is called the "M.A.P." and is stored in the ECU.
