However, even with these features, there is always room for improvement, especially for those who crave more power on the track or the street.
What is an ECU Reflash?
An ECU (Engine Control Unit) reflash is the process of modifying the software that controls your engine’s performance. This software regulates various parameters, including fuel delivery, ignition timing, and throttle response. By adjusting these settings, a performance tune can optimize the engine’s performance and unlock additional horsepower.
