    Replaced the fuel injector.
    The new parts purchased from Ferrari UK are made by Bosch, not by Marelli.
    These are now official parts.
    Just put it on, the mixture is too rich.
    CO value is around 9%.
    The ECU trimmer is on the leanest side.
    Even if the pressure regulator is adjusted and returned to the maximum
    The CO value changes only slightly.
    Aftermarket fuel pressure regulator installed.
    The CO value has dropped to 6%, but the mixture is still rich.
    Leave the ECU trimmer on the thinnest side.
    The pressure gauge attached to the pressure regulator (inlet side) indicates 2.2bar. (engine running)
    Original Marelli fuel pump installed.
    Need a suitable Bosch fuel pump?
    Please someone give me the best answer!
