E-Bike Mileage Correction

[KISATEC]

Hi did anyone work on E-Bikes to adjust Mileage?

i have a Customer with an Haibike with Bosch CX Line Electro Engine.
a good friend from me is a Bikeseller he told me the Mileage is stored in the Engine unit.

He will bring me a damaged module what i can use to test.

i will try and report if i find a solution to change Mileage

Regards
