Are 1999-2005 pcm interchangeable
I've got an 1999 ls1 engine Tow company fubared the pcm. As with any computer equipment as soon as the next one comes out the old is slow and obsolete therefor Can I use a newer model pcm.
With slight mods as ls6 intake,heads,cam the motor is basically a ls6.
What pcm should I start with, I'll have to have it reflashed and have items deleted or turned off
Thanks for help.

The short answer is nope.
The longer answer is that you can switch PCM "years" by rewiring the connector plugs. here's a how-to on switching a 97-98 to 99-02 PCM but the principle is the same for all swaps. You will get an idea if this is something you want to try...
Honestly, however, there is nothing to be gained if you already have a 99. Just replace it with the correct replacement PCM from the auction site.

Yep, the pinouts are definitely *not* the same for 99-05, and certainly not for 99-02 to 03-04. 2004 is the last year of the C5 model. C6 pinouts are definitely not the same.
Basically, each year and each model gm car has a different pinout.

Your first question was 99-05 then you went to 99-02, then talked about 87-88. I think part of the problem here is fingers on the keyboard. Is your question "are the 99-02 pcm's interchangeable?" No way are the 99 and 05 the same.

As my first post said, just replace with the 99-02 replacement (which is an 02 PCM).

Your original question, that I answered was, are the 99-05 pcm's interchangeable. I told you no. What other useful information did you expect. Ask the question you want answered and you may get the answer you expect. Your question was answered by several people trying to help you and you got snotty. Sounds like you've already made up your mind, so why ask.

Tell you what, chum. Go buy your 2005 PCM that is "faster" and "better" and install it. Then report back.
