Hello everyone,

I am DIYer in China. I have found an affordable HV unit in China for HV battey upgrade. It can upgrade my HV battery from 60ah to 160ah. But I have no idea how to program the computer to adapt the new battery. Now it only shows about 89km on the dashboard, with the new battery installed it should shows the range up to 370 to 400km. Any help would be appreciate. Thank you all!

I think I need to add some information to keep it going.
I have ista+ with 4.39.20 installed successful on my computer.

Also I have the lastest programming data 4.48.11 in the system.

My loptop reads the vechicle's information correctly from the ENET cable.

The latest programming data have the I001 firmware for I3 series. Which just launched May or June 2024.

The ISTA+ reads 53 updates available for my I3, so I think I have everything ready for programming the BME (Battery management module? can't recall the exact name).

I think I have two options as follows:
1. Program the BMS to recognize the battery as 120ah, which is fine by me.
2. Program the BMS to whatever I want (ah). I need kindly help to reach either way.

If anyone knows which thread to look, please show me the way.

Thank you!
