Temperature gauge instead of EQ?
Is there any way to switch the EQ gauge to show coolant temperature instead? The EQ gauge is cool but I find the coolant temp to be more informative.

What year is this? If pre-facelift, probably possible through a third party coder.

As for stock I don't think there is an option to change it.

2021. Thanks, I didn't find an option either.

The only displays I know of are oil temperature and transmission temperature.
This may have changed with newer models though.

Facelift don't have it either. The EQ logo also was removed on even later model years.

The EQ gauge is pointless. I've watched the 48v battery draw and there are many times when it's clear the system is using the ISG to add power without the gauge moving and other times when it shows power but there is no amp draw on the 48v system. That said, without truly custom software (not variant coding) I don't think you can change it. Maybe remove it though.

Wish they offered an option to change it.
