Calculation of Wh not correct

Hello ABRP Team,

i like to use ABRP more, but i have the serious problem, that the indicated remaining capacity is always way to less. (I have already lowered the Wh to 230, although i need about 260 and it is still too less)

I even tested this with a premuim account and live data, still indicated too less:

Example: ABRP indicates remaining 6%, Car indicates remaining 16% → trip ended with 14%.

What should i do? Is there a systematic problem? Where should i adjust things?

Car Data:

VW ID.buzz GTX LWB

Thanks a lot for troubleshooting

Daniel
