ECU tuning is a process where the software and settings of a vehicle's Engine Control Unit (ECU) are modified to optimize engine performance, fuel efficiency, and other parameters. Here's a simplified example of ECU tuning:
Let's say you have a turbocharged sports car, and you want to increase its horsepower and torque for better acceleration. A professional tuner would access the ECU's software, typically through a diagnostic port, and make adjustments to parameters such as air-fuel mixture, ignition timing, and turbocharger boost levels.
After these adjustments, your car's ECU will send different signals to the engine, allowing it to produce more power. The result is a noticeable increase in horsepower and torque, providing you with improved performance. ECU tuning can also enhance throttle response, adjust for modifications like aftermarket exhaust systems or intakes, and even improve fuel economy.
