I own a 2002 Lancer oz and i wanted to make the interior look like an Evo 9 MR so I bought a used Evo gauge cluster on ebay and i don't know how to make the original mileage match the used gauge cluster. What do i do? the Mitsubishi dealer ship said i have to send the gauge cluster to a company to set the mileage and all kinds of other crap trying to get more money out of me. So helpppppp. i want the mileage of my car to match the used gauge cluster that i bought.

 

You can't, the mileage is maintained in the cluster. A simple search would have told you that.
