    Good news Codewize. Ross at EFILive gave me a helping hand and John at Tunercat has also. The Tunercat programming cable will now program this PCM per John. We can't read out the PCM yet, but that doesn't matter to me I pull the chips. With the info I got from Ross we should have the other issue resolved. TunerCat and Wester's are very similar and I use a file from TunerCat in the Wester's program to make it work. The problem this weekend was I left my cable at work. We will give it a try tonight.

    Hey AJ I was hoping you could help me real quick. Have you heard of NYC Performance Tuning? They claim to be associated with Westers Garage which is a name i've heard going around for years. I just bought a brand new Shelby Aurora V8 and wanted to put that in my car and have my '95 computer tuned to handle it. I'd rather have you do it. Are you sure you won't do any new tunes?

    That word is: "Don't hold your breath". Been the same since 2005, hasn't it ?

    TunerCat can now program this PCM, so it isn't the same.

    I also have made a huge step in the 2004 and 2005 PCM, but I am stuck on the F'ing DTC that keeps setting for the issue on the 2000 to 2003.

    Re: Any Previously tuned 2000 to 2003 PCM have lifetime tune upgrade

    This PCM is a Seimens and not a Delco/Delphi. The Seimens PCM's are used in a lot of European cars. I have a friend that uses WinOLS (a Seimens friendly software) and I am hoping he can aid in fixing my issue. I sent him a bin file last week to see if his copy of WinOLS could calculate the check sum

    Thanks Edwin for the call
    I had a look and found a place to start looking for that issue



    See the 000075C4 in the second line below and listed above as the CVN?




    And then the CVN from above listed in the second line below?


    Thanks again Edwin
    I hope this is it

    I will email Mr Wright and as for any help he will give me on this

    I wouldn't swear to it but I think my 2001 is also.

    But Sub, one thing is for sure. It is in fact the same since 2005.

    pcmcalibrators,.........Exactly what modifications do you offer for the 1999 - 2003 Cadillac FWD PCM ? What gains, what losses.......... dyno graphs: before and after. Shift points, engine loads, downshifts, injector timing, ignition timing........all with load/throttle position graphs.

    What is/will my money get me with your work ?? Guaranteed in writing.
