The difference between street car and racing car in ECU setting ECU setting is generally divided into two types, one is street car and the other is racing car. For racing cars, because factors such as fuel used, venues, and drivers are all prescribed, the focus of computer settings is how to deal with environmental factors such as weather and temperature that change at any time. The street car is much more complicated. There is no limit to the driving time, and the fuel will change. Even if they all use high-quality fuel, different gas stations will be different. Compared with racing cars, street car modification needs to consider safety factors more, so the computer settings must be reserved. After comprehensively considering the driving style of the car owner and the characteristics of the car model, the settings are made. And even if it is the same situation and the same car, there will be changes, so it is not necessarily the best to use the same data to set. Points to pay attention to when brushing the ECU Many car owners only care about the horsepower, but do not pay attention to the torque. This is a common situation. In fact, you should not blindly pursue horsepower when modifying a car. Before modifying, you should first understand the purpose of the vehicle and the driving habits of the owner.
