Engine Control Unit (ECU) tuning software is a type of computer program that can be used to adjust the settings, parameters, and overall performance of an engine.
It can be used to modify the performance of gasoline, diesel, and other fuel-injected engines, and can significantly improve the performance of a vehicle. The process of ECU tuning software involves the modification of the air-fuel ratio, ignition timing, fuel curves, and other parameters in order to achieve the desired level of power and efficiency.
The most commonly used type of ECU tuning software is a reflash, which is a downloadable program that is uploaded to an ECU. This program is specific to the make and model of the vehicle, and is used to adjust the settings of the ECU to improve performance.
The reflash can include the addition of performance-enhancing features such as more aggressive ignition timing, higher fuel flow rates, and revised fuel curves. It can also be used to reduce emissions, as well as increase fuel economy.
In addition to a reflash, there are other types of ECU tuning software available. These include stand-alone systems, which are programs that are installed directly onto the ECU itself, and piggyback systems, which are programs that are installed on an auxiliary ECU and connected to the main ECU.
