Opcode #20 - State: Invisibility

[Echon]

Parameter 2 has two different values: Normal (0) and Improved (1). Improved Invisibility adds a +4 bonus to AC (calculated into the to hit roll) but does not add the saving throw bonuses.

So parameter2=2 doesn't work for you?

I'm sure it works in bg2. I've submitted an item using that effect into one of the tbg contests (the ring which made you invisible)

[Echon]

What is a value of 2 supposed to do?

IIRC, param2 = 2 is "weak" invisibility - the creature toggles their visibility state each time they perform an action.
