Must the engine control unit (ECU) be unlocked after the air conditioning system is installed?

Hello everyone,
I have installed an air conditioning system in my 35i -1Z-. Everything works perfectly.
Only when the air conditioning is turned on does the engine's RPM not increase, as it should. What else is the engine control unit (ECU) informed about when the air conditioning is turned on?
I already asked VAG if the control unit would be unlocked for this.
When the master finally understood what I actually wanted, he told me: "Generally, this isn't possible. If the vehicle is already equipped with a climate control system from the factory, the control unit will be different."
Now, believe it or not, he's already told me more than I wanted to know.
Who can tell me more about this or immediately provide the login code?

Best regards, Benno

Okay, so far so good, where are the problems?

It doesn't work with my standard Climatronic and the AHF either.
What's important is that when the air conditioning is turned on, the engine doesn't suddenly shut off in fright. The air conditioning signal is there for this purpose, IMHO. Almost, so that the MSTG can already give a little boost at the moment of switching on, so that the engine speed does not drop too much.

I have no knowledge of anything that would need to be enabled for this.
