AAT Stalling: Causes and Solutions

Hello everyone,
My 100/AAT.
'It runs perfectly in limp mode with the MAF sensor disconnected, starts well, and doesn't smoke, but then it only produces around 80-90 horsepower.'
As soon as I plug the LMM back in, it starts shaking and smoking after about 10 seconds, it doesn't respond to any throttle input, and then it shuts down.
The error code in the memory is: 2244, which indicates a problem with the fuel injection start/control.
I have tilted the pump in both directions by very small angles, but there is no improvement. The filter is new, and there are no air bubbles... Also, the resistance of the injector is correct!
What now??
Thank you for your help.

Hello,

Please measure the start of the injection process in the default settings mode.
What are you measuring?

Best regards, Rainer.
