I have recently observed that the feedback voltage from the quantityadjuster on the pump goes to maximum 4,500 Volts when looking in VagCom. This happens even that we request 4,900 in the pump tension map.
This clearly limits the highend power. The curve flatens out after 3500 rpm.
I have tested with the topcover off the pump. When ignition is on and I turn the adjuster to max. by hand. VagCom shows in most cases app.4,850 Volts.
Does anyone know why the ECU is not able to turn the adjuster all the way to the requested and mechanically possible limit ?
I allready searched the Software for some limiter. But didn't find anything yet !
Any help or tip is highly appreciated !
Maybe some other proff. Hardcore tuner here (Eg. Hatemi etc.) Has observed this too !
