What does 'tune' mean in a car?
2 Answers
'Tune' in a car refers to the button for adjusting the audio system, including bass balance, treble balance, left-right balance, front-rear balance, and SVC (Speed-sensitive Volume Control). Car audio systems are installed to alleviate the monotony of travel for drivers and passengers. Initially, car AM radios were used, later evolving to AM/FM radios, tape players, and then to CD players and digital audio systems compatible with DCC and DAT. When using car audio, the volume should not be too loud as it may interfere with normal driving. It is also not advisable to listen to overly soothing music as it can cause drowsiness.
When someone says 'tune' while driving, they're most likely referring to flashing the ECU program, similar to reinstalling a computer's operating system to boost performance. Nowadays, many new cars come with factory-limited engine power. By using professional equipment to read the vehicle's computer data and modifying parameters like ignition timing and air-fuel ratio, the car can unleash more horsepower while also improving fuel efficiency. In the past, modifying required disassembling the engine to add a turbocharger, but now even family cars can gain an extra 20-30 horsepower easily by plugging into the OBD port and flashing a Stage 1 program. However, it's important to note that some brands may void the warranty if the ECU is flashed. For German cars, it's best to go to a professional tuning shop—they also perform dyno tests to adjust parameters and prevent engine knocking. After flashing, remember to upgrade to a high-flow air filter and exhaust for more noticeable results.
