P. Perfect or Simple Present

Hello;

1. I will give you a call when I've made a decision.
2. I will give you a call when I make a decision.

I've read both these sentences in different contexts. Could anyone please tell if there are any differences between them or why the both sentences are considered correct if there's semantically no differance?

Thanks in advance.

Not much different in many cases. The second one could imply that you will call the moment you make the decision.

Graditudes for the quick reply. Now you gave me the idea, it makes sense. However, for some reason the first sentence feels as if it gives the "as soon as" meaning to the sentence. Could that be possible or am I just hallicunating? :)

Sure. It could mean that too.
