    That is the hold up. I can reprogram or recalibrate PCM's to most specs. I can not finish a Package to sell yet. SOON. I will need to unlock more options. As you can see I am into them. I have completed some programming that removed all OBD II functions. This would mean it was no longer OBD II be the definition of OBD II. I have actualy by passed all OBD II test. The good thing on what I did was I set the OBD II readiness codes to Pass. If you when to an emissions test you would PASS the test. Some other systems just turn off the DTC's.

    I have one. If you want it, call me.

    618-732-6215

    I bought it off of ebay to check out a problem on my 94 seville which this one is for. I also have a wrecked 95 Eldo, but I need to keep the puter with it so I can sell the drivetrain. It only has 91k miles on it and is in great shape. I also have all the suspension parts and the Bose stereo that I can't figure out how to put in my seville which has the stock GM system in it. Seems like the amps or the gadget next to the antenae are different.

    It might be faster to pull the flash memories and then read them to get a actual code.

    You need to determine which IC's they are, what processors they are and then decipher the communication they are to use.

    But like they said, screwing up can "blow" a PCM. But, rarely is the PCM "bad', it is just a corrupt flash. So you simply toss back in your programmer and flash it back and solder it back down. The PCM is back in business.

    The fun is then breaking down the OS and figuring out which table is what, which switch setting is what and what constant is what.

    I work on hardware, I am not a software junkie. So the first part is pretty easy. Second isn't my forte....

    Re: PCM Tuning Progam for NorthStar V8's?

    I have one I am not using. I bought it off flea-bay to test a problem with a code I am having with my transmission. I think my torque converter lockup solenoid is not working, but the dealer told me it was not a big thing and not to worry about it except for a small amount of gas milage I will lose by it not locking up. It is a cheap part, but you have to take the tanny out to replace it. I wish they would have put an inspection panel or access panel on the drive chain cover and then I could have replaced the solenoid easily.

    I bought a 95 Eldo that has 91k miles on it that was hit hard on the passenger side, but I drove it home and everything works. I have sold some parts like the bumpers and the ABS pump, but everything else is still there and in excelent shape mechanical wise. Obviously, the passenger side is shot and along with that a lot of the interior. It is shale in color and the fenders, hood, trunk and just a bunch of stuff are in great shape.


    I am new to this place and am having a hard time navigating and figuring things out like not being able to send PMs yet and where everything is. I am a computer tech, although software is not my strength, but this site is hard for me to figure out. Hopefully with a little time, I will figure it out. I even use a site that uses this software and should be able to easily utilize it, but I can't. My messages disappear, they don't go to the top like I am used to. I don't know if my messages are being seen as I have never gotten a reply to questions and offers of a PCM. Maybe I am posting wrong or in the wrong places. Hopefully someone will straighten me out so I am not doing anything wrong.

    Maybe someone could call me and give me a quick lesson on the way to use this site.

    You are posting fine, I'll give you a call later on, I am in the midst of a compressor clutch plate removal that is not going too well....

    You have to have like 50 messages to get PM's. Lord Cadillac or Urbanski might be able to help, but don't post bogus messages like one liners to get the post count up, they get pretty fussy about that. Maybe they can override the PM min count for you.

    This site is a bit more restrictive than most when it comes to things like base
    (not paid subscriber) PM messages, Avatars and some other things. But don't let it discourage you, it is by far the best Cadillac site on the net, and overall one of the best forums there. It is worth the subscription in my book, when I get a few duckies freed up I will sub again....

    Re: PCM Tuning Progam for NorthStar V8's?

    Shot in the dark here, but does anybody have tuning information on a 03 Northstar? This one is running a BigStuff 3 ECU, but so far we have had to figure out all the values for timing, crank position refrence, etc... It would be nice to have a baseline timing curve, and all the values for the crank trigger angle and such.
