MG5 displaying wrong SoC

Hi all, I am trying to use ABRP with my MG5 PFL SR 2021.

ABRP connects to the OBD dongle just fine, but it is reading 8% lower than the dashboard.

I have tried the PID editor in ABRP but it doesn't seem to do anything to the SoC values.

I need to either:

-find the parameter that contains the dashboard battery %,

-or edit the value I already have with a formula.

The PID editor function seems to be exactly what I need, but nothing I change in there affects the SoC. Indeed even if I delete the equation that's already there nothing changes.

Torque displays the same SoC as ABRP.

I am really pulling my hair out!

Many thanks!
