Iveco BSI Configuration swap

[Edc17tricor3]

Hi to all.
I have Iveco Daily with

MCU: 70F3238
Eeprom: 95320

I need to clone it, if I swap eeprom contect BCM not respond on diag anymore

If i try to read MCU i cannot write it because it is OTP

Someone can swap configuration from old bsi to new?
Pin vin,exc

I can pay for work

Atcched both eeprom

Swap MCU and 95320. Just all.

Asking for help, then saying 'solved by myself'

Why do you even ask if you don't want to share information to others

Probably you swapped MCU + eeprom but maybe you have other solution which is worth to mention.

When i see OTP, all is very clear for me.

In this field, i don't try to read and write all the time, because my electronic skills give me solution quicker and safety.

i work alway with what i have in hand (For sure, sometime the help or advice from collegues also welcome)

But in the end, you learn many more when you do by youself.

Swapped MCU and eeprom content.
Sorry for slow response, this is only method when you see 70F not writable MCU

But on vw you can online swop with odis to secondhand ecu np. even with otp .. interesting m8 ///////////////////////////////???????????????

It is completely different

Vw and TC processors have only 1 sector OTP
On this sector is written chipid, this is used for encrypt immo data located on virtual eeprom.

When go online GeKo easy decrypt and re encrypt new data with different chipid

On this body is completely different, ALL sectors of mcu are OTP

All Iveco BCMs (old ones) can be replaced at will. Only the eep code changes. It contains an identifier from the NEC 70F3238 that needs to be changed. Well, and calculate the checksums. With the right equipment you can do this without soldering. On table or via obd in Daily.

You try to make mistery about the tool? For me, 30mn all done on bench.

And this way, i can do with any electronic device.

I wrote that it can be done differently. SMOK has a read/write eep in those BCMs ( 70F3238). My method is just simpler.

Hi ,i am trying to find the id of the nec mcu in the eeprom, maybe it is a three byte id at the beginning of the eeprom file i am seeing?

More needs to change.
