Adamw Posted June 13 Report Share Posted June 13 The GDI pump calibration looks wrong. The number of pump lobes is set to 4, yet the Pump calibration table spans 180degrees. This table maps the profile of the pumping side of the cam lobe so it should only span about 90deg if there are 4 lobes. So either the calibration table is wrong, or the pump has 2 lobes. I recently done a 2.0L R9DA EcoBoost so we have known good data for that engine, but this engine had 3 lobes on the pump cam, do you know if the 2.3 pump/cam is different?
