2002 e825 with T1 controller - BDI adjustments

Does anyone done any tweaking of the BDI range on the T1 controllers and have any recommendations?

My Leaf 22S battery pack(with 3 diodes feeding T1 input) stays at 100% for most of it’s charge and by the time I see 90% on the display I have one trip left and generally return with 65% showing and battery cells at 3.45V.

I have the programming cable and software and feel it’s time to battle this issue in hopes of forgoing modifying the dash glove box so I can see my BMS touch screen display.
