ECU Tuning: What It Does and How It Really Works
ECU tuning is the process of changing software inside your car’s engine control unit. That unit controls how the engine runs. Fuel, timing, boost, throttle. All of it. Most factory settings are not set for maximum performance. They are set for safety, fuel quality differences, and long-term use in many countries. So there is usually some room for change. ECU tuning adjusts those limits. Not in a random way, but by changing specific engine maps.
