Tuning your car's engine can be a great way to get more power and performance out of it. But what is the difference between a piggyback tune and an ECU tune? An ECU tune is a more precise method of tuning your engine. It involves rewriting the factory settings of the engine control unit (ECU) to get more power out of the car. This type of tune is like using a scalpel, as it offers much more accuracy than the built-in melodies.
On the other hand, a piggyback tune is designed to provide only weather changes and does not offer any adjustment capabilities. It does not provide any control over any of the other variable parameters that affect the vehicle's running, such as camera synchronization, refueling, speed limiters and accelerator response. A piggyback tune is similar to a “chip tune” in that it connects directly to the ECU. However, it does not rewrite the factory ECU setting.
Instead, it alters certain signals and sensors to achieve the desired result. This means that the factory DME setting remains unchanged and the piggyback tune is “tricking the DME into generating more power”. There are two types of tunes: piggyback tunes and flash tunes. A piggyback tune offers superior integration and usability features, while a flash tune provides precision and customization.
Flash tunes can be adjusted and customized to create the perfect tune for your car. Flash tunes can generate more power than a piggyback tune if you go to the irregular limit. However, both types of tunes have their own advantages and disadvantages, so it is important to consider your needs before deciding which one is right for you.
