There is no such thing as an LTN combinator that you can change the values of yourself so I don't understand your question. I have used this mod together with LTN though and it works great.
@zomis LTN Combinator is another mod https://mods.factorio.com/mod/LTN_Combinator_Modernized which is based on combinator entity and adds an entity called "ltn-combinator", it provides a fancy UI for LTN combinator setup.
