Hi,

I'm looking for a structure document for ECU ME73H4 EEPROM.
This type has at least two different variants, or even more, the two is what I have already seen.

The car that I'm working on/playing with (and using regurarly) is a Fiat Punto mk2a/mk2b 2002/2004 1.2 16V.

I already found some parameters in the EEPROM with the help of Multiecuscan, but maybe there is a ful documentation of it out here.

So I'm looking forward someone posting useful info about it.
Thank you in advance!

p.s. if no one will post, and there will be some interest about the information, I will share what I have already found (odometer, number of writings, etc.)

So far, these are the informations that I found and documented (there are some others which I didn't write down, but pretty easy to find in the dump, like programming date, etc.)

Odometer:
---------
0x18 .. 0x1A, Reverse order
pl. BC CE 1A -> 1A CE BC -> 175685,2 km


Odometer at last programming:
-----------------------------
0x24 .. 0x26, Reverse order
eg. 79 0B 0A -> 0A 0B 79 -> 65829,7 km


Number of programmings:
-----------------------
0x22
