I have a 2004 Chevy Cavalier 2.2 Ectotech. The computer needs to be replaced. I plan to get a used one from an identical vechicle. Will this computer work ok, or do I need to have it reprogrammed? Thanks for the help.

Re: Replacing the cars computer
As long as you get one from the same year and same engine/ trans. you should be fine. Actually you may even be able to get one from a different year just as long as the engine/ trans. is the same. Your local Chevy dealer should be able to verify it for you.

From a legal stanpoint? Do you have inspections that require stock equipment? Might want to be careful there.--other than that from a mechanical standpoint the outside diameter of the tire needs to be real close and honestly it sure sounds like youd be there. Maybe about ten milimeters off in total--but that would represent about 3 mile per hour difference in speedometer reading. not bad. Hope I helped. Thanks
I replaced the radio on a similar car with an identical junk-yard radio/cd player. of course it was locked. I went to the dealership and they were nice enough to plug a hand-held computer under the dash and unlocked it for free. Took about 5 min. Hope this helps.
