I was wondering if someone had a good idea of what is stored on the eeprom?

I've found this image which explains some things.



It seems like most the bits after 0x130 are adaptations (and maybe DTCs? or are those not stored at all), as clearing codes resets most of the bits.

What I'm most curious about is the 4 bytes starting at 0x112. Does anyone know what they represent?

I have an ECU here, it seems every boot those bytes are different. When I write to it with argdubs tool it fails verification. If i dump the eeprom and do a diff to the last read though, the only bytes not matching are 112 - 116, which seem to be basically random data each read.

I think if I keep booting in bootmode it stays the same, though (so something in normal ECU running keeps writing different values there, I guess)

Any ideas?
