Hummm, I think I read on the WIS that the ECU controls ionization at every combustion so detecting detonation. I am sure it use detonation to understand which cylinder is firing when cranking. The ECU sends sparks to 1-4 and 2-3 simultaneously and only when a cilynder fires it knows how to phase the ingnition.

The Trionic 5 does not use detonation sensor.

About the FPR I have already changed the hose with a silicon one, so I exclude that FP is not regulated according with the boost pressure (unless my PFR is defective).

However, if the FP would not be enough at high RPM this would lead to fuel starvation and injectors can not compensate with a higher duty cycle.
This is the same effect that a plugged filter would create.

I think that there is not a control on fuel pressure. It simply is eonoug or not. And if it is not, the engine will be less performant while truìying to adjust at it's best. If then the fule pressure decreases too much a CEL will be thrown may be with 7 flashes meaning "bad adaptation".

Bad adaptation means that the ECU has not been able to set the O2 value to 1,0 volts.

I am going to open the thread you suggested.

ciao
