This is the original file 0261206276 (not tested), you need to convert it to BCB format if you're gonna write it with Galletto 1260.

To make it virgin you need to put ground to SDA and flash the COD file you find here.

Next remove the groumd to SDA and flash it with the ori file.

Remove immo box before installing the ECU to the car.

Here you find the COD file

Hello.
Pin SDA must be connected to ground while I write COD file or only while I start ECU?
I connected pin SDA for moment, while I started ECU and FES showed programmed date: 00/00/0000.
It's enough?

Yes, keep SDA to ground only while writing the COD file, Km will show 0 Km at this moment. Then turn off ECU and remove SDA to ground and restart ECU and write ori file.

P8, P17, P18 - 12V
P11 - K-Line

Gelletto shows "Errore invio INIT2", while I try write COD.
ECU is detected correctly.
What is a problem?

[eyomsoft]

No ideas?
I don't find resolve in web. Most problems are with INIT1 and INIT2. I have only INIT2 error.

P10 needs +12v for programing

P11 - K-Line

[eyomsoft]

Yes, I tried with P10 connected to 12V. Result is the same "Errore invio INIT2".
Power supply voltage is 12,1V
Ground is connected to ECU case.

Are you using files in bcb format? Maybe your galletto is not working well, I don’t know. I do these ecus all the time with this procedure without issues. Next time I’ll make a video for you.

Ok, problem is solved. I used other galletto interface.

I have different question.
Does anyone have pinout of MCU in this ECU? Is this C509L?

Hello Everybody,

I have read all this thread with attention to find some answers to my questions, so many thanks to all contributors with their precious experience.
Actually I am rebuilding a 2.0 TS petrol engine to replace the old 1.8 TS engine of my Alfa 156.
The ECU M1.5.5 of the original 1.8 TS is working fine but I guess I could have issues when the 2.0 TS will be transferred in the car...

Can I buy a used 2.0 TS ECU M1.5.5 and put it in the car without any "immo" issues ?
Or do I have to reprogramm it with the procedure described in the previous posts ?

Thanks for your answers
