'supervisor display' question
OK, I have a 2006.5 Optima with the 'trip computer'. This is nice because it has the outside temp, but I sure would like to have instantaneous mpg on there. I think some markets get this, but not the USA. Does anyone know where the display processing happens? My question is -- if you put in a UK or OZ module, would you get the functions for that market? Or is the calculating done in the engine ECU, so the display wouldn't be right if not matched to the ECU as originally.
