There is a mode on the LCD odometer if you hold the trip reset button in before you start the car you can cycle threw different display modes. RPM, coolant temp, KM, etc.

Maybe not, i thought ide ask though.
The display had somthing like 20 different pages that showed different things the car was monitoring and would display but like i said there was a few things that was posted as "unknown" or somthing
