I'm looking for a eeprom dump of a 0261207967 Alfa 147 GTA ECU.

Can someone help me with this, not the engine MAP.

For what exactly ?
You can just fille the EEPROM with 0xFF and the ECU will recreate the content after ignition is switched off in the afterrun.
Afterwards the ECU is virgin and will pair with the IMMO again.

If you remove the K-line wire it will stay virgin forever,
but the code lamp is on as the Body computer will detect no communication.

 Hi, I needed to clone the 2.0 ecu to the 1.6 after the engine change. But I managed to find it and it's all right. It works.

Exactly I needed the eeprom of the alfa romeo gt 1.8 twin spark (0261208725-1037370360) because the engine is 1.8, I found the flash file but I miss the eeprom file. But until I find it I have to be satisfied with this.

You dont need the EEPROM data at all.
Flash the bin matching your engine to the ECU (almost all 4 CYL ME7.3.1 are the same hardware).
Then write a file created in the hex editor with all FF to the EEPROM (CSpin4.7).
Turn off ignition, wait ~10 seconds, turn on ignition.

The EEPROM has now been recreated by the ECU, as this is exactly what happens in factory.
You then have a "brand new" virgin ECU.

I've just tried it but the machine doesn't start, or at least it starts but has errors and turns off. I tried to read the eprom after this and the file was encoded up to a certain point then there are all "00". I attach image.

Can you check if I did it right?

Eeprom was recreated correctly, the empty sections are normal (they are unused),
but they have the correct checksum to the right.

Also the ECU already paired itself with the IMMO correctly which you can see on the 0x25 bytes (which are after or before the immo code, dont remember which way round) on page 5&6.
If its unpaired its either 0xDA or empty.

Did you delete all the error codes and try to start again ?
If it does not work it is more like hardware around your ECU than the ECU itself,
everything looks totally fine.


If it starts and then turns of it is NOT the immo, if the immo is active it will never start for these ecus as there is NO injection at all then.

I made a diagnosis and the program did not give errors. But it appears in the instrument panel. I also tried to load this eeprom virgin on the 2.0 ecu that normally works and that doesn't work either. Then I reloaded the eeprom of 2.0 and it works again.
