    Have you checked the wiring for the Z32 as its 3 (or 4 for prefacelift) wires off the loom into 6 on the Z32 AFM ?

    Should have an orange sticker on it, if its a genuine one.

    Did we establish if its a lambda ECU or not ? Here's a pic of a lambda one (39F05).

    Yes then. 3 wires on a lambda loom to connect to 3 of the 6 pins on the AFM.

    If that's the case then you are looking at an AFM or AFM wiring related problem so check both
