They go by many names, P01, P10, P12, P59, E38, VPW, '0411 etc.

I added some sections to the XDF to look at the data in the parameter blocks.

I dont know exactly whats in them, but I can speak to that area generally. Thats the Paramater block segments on the flash. They are mirrored to SRAM at FF8000, and are used to save that persistent data to flash. When it is being persisted some operating systems move the active block to the alternate param block, and others always use the same one. So Dynamic Data 1 is the Param block at 0x4000 and Dynamic Data 2 is the Param block at 0x6000. It looks like they are named 1 and 2 for the two copies. Only one will be active at any given time, and the other should have FF in the whole segment (erased). So the question would be to figure out what saves error flags to SRAM at FF8040 (as the offset is 40 in the XDF) and there will be a flash backups of that data at 0x4080 or 0x6080 as Dynamic Data block 1 or 2 error flags, and the other will be blank - FF.

With that XDF I can't change VATS to 2
Only 0 and 1 can be used
Is it a bug or it supposed to not let disable VATS ?

Isn't it none and serial?
3rd is PWM which is P01 only?
Pretty sure. maybe the each have the numbers mean a different feature.

0 -class 2 data (bcm)
1- PWM (passlock ?)
2- VATS disabled
I used another XDF to turn it off

Number might mean different for P01 and P59. I don't remember ever seeing anything other than off and serial for P59 in UniversalPatcher.
EDIT: I've only been messing with 12587603

depends on the os I think. if its confirmed its 0 1 2 in 7603 then xdf needs updating as we know exactly what os its for.

Thanks so much for this NSFW, I’ve been looking for a way to utilize the shift light functionality since I’m running a manual.
