What does stage 1 car tuning mean?

[AugustMarie]

Stage 1 car tuning refers to improving engine performance by modifying ECU software parameters without changing any hardware components. Below is expanded information about stage 1 car tuning: 1. Stage 1 ECU tuning involves adding the most basic ECU program to the vehicle's original factory ECU, thereby increasing horsepower and torque. This only requires matching with the original factory hardware. 2. Stage 2 tuning refers to adapting an ECU program that has been debugged for certain modified hardware and adding it to the original factory ECU. Compared to stage 1, it significantly increases power, resulting in noticeable performance improvements. However, it may cause some damage to the car's hardware and increase the load on the components. 3. Stage 3 tuning involves extensively reprogramming the ECU, installing larger turbos and intercoolers, and replacing some high-strength parts. After such modifications, the engine undergoes substantial stress, which may shorten its lifespan to some extent.
