Which is better, Fuai EFI or Ye Sheng EFI?

1, automatic control. Ye Sheng EFI system consists of six main parts, including ECU, throttle body assembly, intake pipe assembly, fuel pump, temperature sensor and oxygen sensor. Except for the oxygen sensor, the other five parts can be made in Ye Sheng. Fuai EFI also includes ECU, throttle assembly, intake pipe assembly, fuel pump, temperature sensor and oxygen sensor, but these are not made by ourselves.

2. cost. Because most parts of Ye Sheng EFI can be made by ourselves, the cost is relatively low and the reaction speed is good. Fuai EFI cannot control itself, so the cost will be high and the reaction speed will be average.
