ECU OPEL 1.7L/TX2, Cant write E2P?

[MYMN]

Hello,
I want to clone an ecu from opel corsa ....ISUZU 1.7L/TX2 DIESEL
it is impossible to solder / desolder eeprom 25320, I have read on board, but I can not write on the eeprom of the new ecu.
, though I can only write his original dump

I tried with xprog, vvdi prog but same result, can not write

is there a solution?

MCU Quartz I connect to GND and then read ....

Try, download your 1st image and see you can read the text? I can but only 'COM3' I think !

Want to see from what address the programing getting start error.

the error starts in the 1st address

If having UPA-USB you should try it, two more features may be useful on you case are you know which pin is over loaded and reading status register for SPI which Xprog absent. But I don't think the cause is status register because error start form address 0 (which means locked all)

you can still cut the memory, do it without crippling

Hello MYMN, was it possible for you to finally read and write the eeprom 25320?

Did you need to do anything else to clone this 1.7L / TX2 ECU please?


Thanks.
