I have a 2004 Flex Tahoe that came with 7603. I installed e-fans and modified the PCM using the XDF found here for that OS and flashed via PCM Hammer. All good. Awesome, in fact.
However, a while back I swapped fuel pumps and it never registers full after a refill. There's a fuel calibration available - 12597473: New calibration to correct fuel gauge not reading full when fuel tank is filled. I couldn't figure out how to flash just the calibration via SPS/Techline - it wanted me to also upgrade the OS to 12606960. Prior to putting in the e-fans and modified 7603, I flashed the full she-bang to a spare PCM and filled up with gas. Gauge registered full!
My question is this - can I use the 7603 XDF to perform the same parameter modifications for fans to the 6960 OS? I compared the outputs using a diff tool of TunerPro "Save data to text file" functionality of both unmodified BIN and can tell there are differences, but the "fan" section lines up perfectly. I made the modifications and saved the bin file successfully and PCM Hammer says the checksums are ok. Just wondering if I'm asking for trouble or if all will be fine. I'd really like to have a full fuel gauge.
OS 12606960 replaces 12585950 and 12587603 - which one would think they're from the same lineage.
Using XDF from older OS (7603 on 6960)

I don’t know the answer, but I’m interested to know what you find out.

Re: Using XDF from older OS (7603 on 6960)
The standard answer is NO ... The XDF must match the OsID!
However, sometimes similar oses partially align until the point of a newly inserted parameter, then from that point on the addresses will be off by the inserted parameter size ...
If I knew exactly what parameters you change, I would look them up and see if the addresses match each other.

Re: Using XDF from older OS (7603 on 6960)
I guess that is a bug with earlier version of firmware you have. Updating via sps to latest version for your bin should fix that bug.
Than you can use Universal patcher to add the e-fans mod.

What do you mean? I used SPS to try and update just the fuel calibration on 7603 but it forced me to update OS, too.kur4o wrote:I guess that is a bug with earlier version of firmware you have. Updating via sps to latest version for your bin should fix that bug.

Also, made a few edits to 6960 using 7603 xdf and Universal Patcher corrected checksums. Good tool, thanks for your efforts.
Re: Using XDF from older OS (7603 on 6960)
You are headed for a soft bricking the pcm, with possible engine fireworks.
Sps won`t allow fuel segment update only, because fuel segment is tied to newer OS and will likely not work with older OS. Just update the file per vin and than retune with universal patcher.
Look at the screenshot.

Ok, modified the stock 6960 bin with Universal Patcher.
What does it mean when the logs show a patch loaded (flex, lean cruise)? Stock is L59 flex.
Also, for grins, did a hex compare between the TunerPro with 7603 XDF bin of same OS (6960) and the Universal Patcher. I'm not skilled but the differences could be attributed to something I might have missed in setting parameter values between the two softwares. Seems close, but I am not even a beginner at this point.

Re: Using XDF from older OS (7603 on 6960)
mattbta,
After you upgraded to 12606960 and before you modified it, did you create a backup ??
And are you willing to share it ??
Thanks
-Enjoy

Yes, I have unmodified bin files for both 7603 and 6960 from my Tahoe I can share. What is the preferred method to do so?Gampy wrote:mattbta,
