i have not yet driven enough to see how my car adapts the mileage to to new battery capacity - i could reset a couple of learned values but unfortunately there is no clear option to enter a new capacity value, i think this is embedded in the software of the SME and/or EME unit which is different for the older and LCI version of the i8 ....
i found a command for resetting the single cell capacities and setting a new capacity per cell pack but this is done in percentage so i wonder what happens if i reset the cell capacities and set a new 100% capacity for all cell packs - i do not want to fuck up my work by disturbing the software so i will first take some time to see if the other resets will prolong and adapt the mileage....
I already noticed there was a small adaptation in the hidden menu where the net capacity adjusted from 5.2 Ah to 5.7 Ah but i guess this adaptation will continue within the set margins of the software...
just the 6-7 years younger age of the cell packs is already worth the money but i hope my work will translate in a substantial higher mileage in the end...
i will post my findings after having driven for a longer period to see how it develops !
Hello sire!

Just load the HV battery to 100% and drive the car with "pure EV mode" AND Eco Pro. Anything above ... 35-40km means the car really uses the bigger battery capacity. Rudimentary rule of thumb:

Pre LCI = 25-30km of range (Eco Pro + sensible country roads driving with speeds around 80 kph and temp around 15-20 C).

LCI = 45-50km of range with similar matter.
