Therefore, the price of the first-order program of cars on the market now ranges from 5000 to 7000 yuan. It costs about 5000 yuan to brush the first-order ecu for naturally aspirated vehicles, and it is more expensive to brush the first-order ecu for turbocharged vehicles.
Brushing ECU may bring some negative effects:
1, which requires higher gasoline quality. Some vehicles originally used only 92% gasoline, but 95% gasoline was needed after ECU was brushed, and higher quality gasoline was also needed as fuel for engine overclocking.
2. The requirement for temperature is higher. If the engine works over frequency, it needs to provide a better cooling system, otherwise it will affect the life of the engine.
