Fiat Punto 1.2 IAW 59F.M2 hw303 Immo off or Clone

[aqua_life]

Hello,
I have here faulty ECU from Fiat Punto 1.2. Two coils not firing.
ECU is IAW 59F.M2 HW303
Inside is processor ST10 and I am able to read this file with FGTech. File is attached.
I have here a good used ECU IAW 59F.M3 HW303.
Can I use this ECU and write my file ? I think yes because HW303 is the same.
To write file I think I must do boot mode, so I need to make a hole on ECU case. Correct ?

This ECU has eeprom inside ? Should I also modify eeprom ? how ? FGTech can´t read eeprom.

Sorry for too many questions, but first time with this job.

Thanks for your help

M3 instead M2 wont work.
M2 instead M3 work.
M3 ECU have different hardware (lambda,camshaft...etc)
You better fix faulty ECU or find good M3.

With fvdi make Virgin used ECU make ignition 1 minute on then off one minute Car starts no problem

Best solution and cheapest is to buy second hand virgin ECU plug and play software for this is about 270 euro so not worth doing.
