Hi, could someone please remove all the EGR stuff from this engine ECU? Engine is without EGR already.
Tried to run it as-is, fuel trims stays at 0% and doesn't change at all but seems more stable than old ECU which is acting weird.

It's my old work horse for 7 years.



Audi A4 B5 1.6 facelift, ALZ, Simos 3.4A

Benzin Simos 3.4A 0007

Thank you very much.
