If you look at the 1024 KB binary file that you can pull with heaps of different software, you'll see that most software when writing to the EEC-VI via CAN/OBD (the way that men do it) that nothing before memory location 0x10000 is written to because that is where the RTOS lives. Even if you try to write to these area's I would say it is unlikely that it would work. Heres code from my spanish oak flasher, it doesnt even bother to try to write anything earlier than 0x10000 because its probably not possible without some sort of systemSupplierSpecific sort of level of access.

Code: Select all

for (int i = 0x10000; i <= 0xFFC00; i += blocksize)
{
    addTxt1("Uploading Flash Memory...\r\n"); progressBarPcmFlash.Value = (int)i;                   
    transferDataUDSFord(flashData, i, blocksize);  //Service 0x36 transferData our upload service
    if (i == 0xFFC00)
    {
        addTxt1("Finalizing Download to ECU...\r\n"); // ECU has finished receiveing data via 0x36
        successfulFlashWrite = true; 
    }
}

What are you actually trying to do?

Edit I saw you were looking for the Serial Number, that is located at memory location 0xEFF0 (Note you will that this location is before 0x10000, and thus cannot be written to, which is why as we know, You can't just edit the serial number of a Spanish Oak PCM.) Hope this helps.

thanks for the reply, I have variant tools and been able to retrieve the 1024kb binary, this time I thought I'll try K-tag at a BDM level to read it all, but it seems to read only the micro.
By the way your PCM tool looks neat, nice one! I'm sure there is market for it.

I'm aware of the S/N offset value thank you. Overall, I'm looking at editing the PCM S/N as stated.
I have tried in the past changing the value, but it reverts back of course.

So, it's fair to say no one has attempted it yet or been able too?

thanks

There was a rumour of it being done, but nothing public. 80gus would know, but I doubt anything will get let out of the bag.

Hi Hjturbo,

thanks, mate, for sharing (your always on point!). I would agree it can be. Just need more seat time to do this or of course lean on *80gus for a few pointers

[hjtrbo]

He runs a good business. I can sense a rejection lol.

[abs351]

All good, I'll work it out when time permits.

Did you crack how to edit the serial number yet?

Hi mate,

I had to put it on ice for the moment, other projects and life aspects gotten in the way. Do you have any traction on this yet or anyone else you are aware off?

thanks
