What Does Stage 1 Tuning Mean for Cars?

[Duncan]

Stage 1 tuning for cars refers to enhancing performance by modifying ECU software parameters without altering the hardware. Here is an extended introduction to stage 1 tuning: 1. Stage 1 ECU involves adding the most basic ECU program to the car'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 with certain modified hardware and adding it to the original factory ECU. Compared to stage 1, it significantly increases power, leading to a noticeable improvement in the car's performance. However, it may cause some damage to the car's hardware and increase the load on it. 3. Stage 3 tuning involves extensively flashing the ECU program, installing a larger turbo and intercooler, and replacing some high-strength components. After these modifications, the engine undergoes significant stress, which may shorten its lifespan to some extent.
