AFN has 110 horsepower and uses VTG = vacuum-operated turbocharger.
AHU is a 1Z engine with 90 horsepower, and the wastegate is a pressure-controlled system.
Whether you can flash it depends on whether the hardware is identical in both. However, both engines were available with different MSG hardware configurations. Therefore, no one can help you without the part numbers.
Whether someone will help you with the chipping process - even with part numbers - remains to be seen

(especially since you are in a forum of a chip provider).

Sure, here's the translation:
"Guste" is a German word that means "gust" or "gust of wind." It can also be used to describe a sudden burst of something, such as laughter or anger.
