I’ve been having troubles with my 1991 Century it’s been having trouble I can’t seem to diagnose so I purchased a re-man computer so my question is does it need to be flash if so can i do this at home or where can i get it done cheaply and if i try to use it with out getting it flashed first would it hurt anything?
thanks in advanced for your answer!
P.s. pardon the poor grammar

Your OBD I Buick computer is hardware driven and not software driven.

This means removing the program chip from the old computer, and installing it into the new computer.

Where would the program chip be?

There is an access panel to remove, on the computer board you will see a removable PROM. There should be instructions with the replacement computer.

Follow up question the re manufactured computer came with a prom chip do I use the one that came with the one I just bought or the one from my car?
