The needle lift signal should look somewhat like the left or right part of this image:
What do you think about the modulating piston movement sendor (G149)? It is used by the ecu as a feedback on the N146 position to determine the actual injected quantity.
I have a pot between pins 2 and 3 of G149. When I increases the resistance, the ecu is fooled and the actual injected fuel quantity goes up. At idle I can see the consumption go down on the scangauge as I increase the resistance, when in fact the injected quantity actually higher.
I do not really know the signals specifics and do not have access to equipment to look it out.
