So, if true, what does it tell about the fuel system? If I understand the idea correctly, the fuel pump must produce pulses of pressure at a frequency somewhat higher than half the sample rate of the FFM, right?
Is it normal to have a pulsing fuel pump?
Or could it be that just below the 100 kg/hr the fuel line begins to operate like an organ pipe, providing high-frequency flow instability that could trick the system? Is it even possible to tune a system like that?
Also, what factors may prevent FIA from understanding how the system works or verifying whether such a system is indeed in place? It seems they should have a good idea of how it should work if they could provide specs for the new generation of the sensors.
Or it was a disclosure of the information by Ferrari, which is a part of a settlement?
