Hello,
I don't like dragging people away from one site to another but the more rabid PCM hack geeks are on a different site. I urge you to take a look at something on the link below called "Universal Patcher". It seems to have an ability to tease out things in an XDF that don't require IDA Pro or Ghidra but I don't think it'll be much help at breaking password protected XDF files.

Do you have a better description of these tables, size, naming, descriptions. I think I can add them fairly easy , if I know what I am looking for.
There is at least one unlocked XDF available:

I have no idea how complete/correct it is.
Looks correct, but massively incomplete unfortunately. Also not as well organised as the locked XDF. Anyonw know who wrote the "Operating System 12587603 - 1Mb PCM - 2004 model year.xdf" ?Originally Posted by joukoy
Kur40.. it should be the max gear table. I've located it in my 6125 xdf
blistovmhz,
Can you confirm you need this table added.
Thanks for pointing that, It seems a valuable item to have defined.Stokes1114

Interesting topic, I've never had a need to do this but does this look like the values that need to be altered? How do you get it into "Urban mode"?

Yea, absolutely. Any way to force hold manual first. Without it, truck upshifts into 2nd at the most inopportune moment, resulting in a sudden decrease in torque, thus increase in traction, thus a barrel roll :D.
Which XDF are you able to add this to?
As I said, in HPtuners and EFIlive, they refer to this as D1Urban, and it works mint. Hold 1st all day with any 4l80e
Ish/not-really/sorta?
What exactly do you need? Which XDF would be be adding them to?
Getting the size, I have no good way to do. I know what values I have programmed in my old BIN, and I can search for them and find roughly where they begin/end just based on the known values.
Where would I get started?
