Hi all,

With all the discussion of the various PCMs used, I thought this info might help:

Hope this helps.

NSFW,

I have a 2003 P59 PCM here with service #12576106, hardware #12570558 (drive by cable) that has the Intel AB28F800 flash chip in it. PCM Hammer will not read it. The BDM can read it, but there is no proper BDM config file (.xml) for writing to it. I'm happy to send it to you if it helps.

It's my understanding (I'm not 100% sure on this) that the 1 meg Intel chips only show up in the 2003 P59's.

There is another 2003 P59 with service #12581565, hardware #12575502 (drive by cable) that I read somewhere it has the Intel chip as well, but I don't physically have one. It's in my research notes though.

Let me know if you want the PCM I mention at the top of this message. I've completely disassembled it and deep cleaned it before re-assembly. I do not think it's dead either. The BDM will read it. Just can't write to it without a proper config file.

Peeked into another Os, this time 12579405, an Os from a 1m Intel chipped unit.
And as expected no Amd code as it is prior to the appearance of the Amd chips.

Unfortunately the hardware/service numbers are not stored in the bin file either so unless you can verify the PCM is virgin you pull tune files from you'll not have that information.

That list is incomplete, erroneous and in my opinion woefully lacking in detail.

The Hardware Number is embedded in the bin, the Service Number is not.
The following is whats easy to glean from a bin that describes it:

• Hardware Number
• Operating System Number (OsID)
• Broadcast Code
• Calibration Number
• System Calibration Number
• Engine Calibration Number
• Engine Diagnostics Number
• Transmission Calibration Number
• Transmission Diagnostics Number
• Fuel System Calibration Number
• Speedometer Calibration Number
• Serial Number
• Vehicle Identification Number

I do have some ideas for some other bits, just haven't set down to it yet.

Personally, If I do not know the information about a bin or even wonder about it's accuracy, I do not want it!
What I am interested in is purely Manufacture originals ... I have no desires to be involved in a repository of "Tunes" by every Tom Dick and Harry tweeking fuel trims et al a point or two and calling it their tune.

I can confirm that hardware number does in fact describe a 1m Intel chipped unit.

Dude I wrote most of this software and I'm not entirely clear on this stuff.

Based on that chart it sounds like you're saying there's effectively 3 kinds of hardware that people need to be aware of:

1) P01 - all are usable with DBW or DBC
2) P59 without IAC - usable only for DBW
3) P59 with IAC - usable for DBW or DBC

Related question - do you know whether there's a hardware number that indicates a P59 with an Intel flash chip? I'd like to experiment on one of those before I take another shot at AMD, but I'm not sure how to identify one without opening it up.

Yes you are correct. I have flashed all different tune files in all different P59's and not had any issues. The PCM listed above by DavidBraley I have not added to my list. I actually ran across one and hadn't had a chance to mess around with it to see what it did and didn't have.

The list is basic because that's all it needs to be. I know all of the information you listed is in the binary. If that is information you need listed out for a binary then more power to ya. It'll be a paragraph long file name lol.

Hi all,

Can someone tell me if the XDF for a given OS, such as '2088, will work for BOTH the V6 AND the V8 Vortec engines!
I have 2 '0411 PCM's out of V6 S/T SUV applications.

Thanks,

Mike

It'll work for the any bin with the operating system id (OSID) 12202088. V6 and V8 isnt relevant to the OSID.

Thanks Antus.
That's what I thought, but wanted to be sure.

So you have flashed OsID 12579405 on one of the following Hardware ID's, No issues, meaning the Os was happy??
12583659
12589161
12589162

A good test would be something like a vin change. The flash tool kernel should handle both chips at os write time, typically, but the question is if an intel os can update the paramater block on an amd flash chip with the factory reflash code when it needs too.
