Hi. I have a 1992 Caprice with the digital speedometer. I want to know if anyone knows how to switch between mph and kph or if it is even possible. Also, the speedometer is very precise, but not accurate: eg --
22.5mph indicated = 25mph acutal
30mph indicated = 35mph actual
50mph indicated = 60mph actual
80mph indicated = 95mph actual
Anyone ever encounter something like this? The car used to be a police car, if that matters. Thanks for any help.
