Hey all I have a 2012 Grand Sport that I acquired recently. The car is now certified for the US market but it has the Canadian market instrument cluster that includes the speedo that goes to 300 along with oil pressure and coolant temp in metric measurements. Is there a way to get a used US spec instrument cluster for the car and have it programmed with correct mileage? Also will the sending unit from the CPU have those coolant, oil pressure and speedo readings reset for the new US instrument cluster? Would a company like USSpeedo do this work or a local GM dealer? Thanks in advance for the help!
