Sorry, if this has ben asked and answered before. If so, please give me a hint where to look

I`d like to limit the range of ed-e`s ability while keeping the ability to target cloaked enemies (assuming that dies actually work )
EdE gives a perk named "Enhanced Sensors" which gives "improved detection" with an value of "1" ond Entry point.
I wasn`t able to find any further information as where to find or being able to configute the improved detection.
I searched everywhere i thought to be logical in the GECK: scripts, spells, globals, settings ... nothing ...

Help please

I haven't looked into it. But since it's changes an entry point. I think it might be hard coded into NV. So I'm not sure if you can even edit it.
