What's the matter with MG 3 burning gas, shifting gears and flameout?

When water temperature signal, cylinder pressure signal and speed signal are provided to ECU, gas will be used when there is throttle signal. Gear shifting and flameout may be due to the interference of vehicle speed signal, which was not provided to ECU correctly, so the system stopped gas supply at once, so the flameout was pulled! thank you

There is another possibility, that is, it was not debugged well, the air-fuel ratio was too low, and the gas concentration was too low when the speed increased, so it turned off!
