    will this PCM work in my Eldo?

    I've narrowed down my no charging problem to a bad PCM after reading Mark C's informative post. I have one located. same serial # on both, however mine is a 95 Eldo "Y" vin and the other is from a 94 STS "9" vin. I thought the motors were tuned differently? is this computer going to work in my car? why would they give these computers the same serial # if they work with 2 different engines?

    Yes it will work. However you will need to take your car to the dealer to get it programed to your car!.

    I thought the 95 year did not have to get programmed. I thought that started in 2000 where the computer had to get programmed to your vin.

    Same reason my generic PC doesn't run like your generic PC: different programs.

    Not so with 2000+: Individual VIN-specific PCM's from the factory. (???? 95 and back had programmable ECM's ???)

    Heck, try the "new" ECM .........It may work. If not, have it reflashed for your car's VIN.

    maybe I got the year wrong. someone posted that on EBAY there is a service that will program the PCM for the years 1996 and newer. has anyone ever changed the PCM or a 95 and not have to program the new vin # into it? if I do have to get it programmed, what does the dealer have to do? can I just bring in my new computer with my cars vin# or do they need the car? I know a guy that works for Caddy, maybe he can just run it through.

    Get to Wester's Garage and ask them. They're very big in the PCM/ECM programming business. Any other speculation is subject to research from someone in the full-time business of PCM work. Hearsay won't work when you're trying to run a Northstar and its vehicle.
