Opel Corsa D KM Change in ECU eeprom M95320 (Adress)

**Dobermann** · 22nd December, 2020, 06:33 PM

Hello Friends,

did someone know the right adress in eeprom M95320 (ecu marelli MJD 603.S1)

maybe carprog can change this value to 0 my opcom cant.

i want to match this used ecu to other car so i have to reset this ecu.

i have read the eeprom and i have the login code.

reset was possible on table with opcom

opcom change some bytes and tells me reset succesfully.

i can write the original vin nummer with opcom to the eeprom but if i swich power of the old vin number is back.
i dont know why the old vin come back. maybe stored in other chip too.
maybe vin stays if i match to car. l will try.

i know km is not importand for matching ecu to car but i want to know where the km are stored in eeprom.

OPcom can read out the km and show it

i found out if i change adress 00E1E to FF or 0 the Km in opcom shows 0 but shows me DTC eeprom error.

maybe the km in eeprom will be changed if i match this used ecu to car (BCM) and ecu will take the km from BCM.

did someone know ?

eeprom file is attached

thanks !

thanks its intressting but not what im looking for !

this is onyl importand i think if you want to make immo off.

i want to match the ecu and if i protect the chip maybe i cant match to car because the data from BCM cant be written to eeprom. dont know.

Hello esse,

short update. i testet your file ! KM shows 0 km in opcom same like my solution but i have ecu eeprom error as an DTC.

i dont know if this is important or impair the ecu funtion.

Hi

Km have nothing to do with adaptation in this ecu, and it can't change in ecu from bcm or dash, if you have the pin you can adapt ecu to car with opcom, you must reprogramming ingectors, if you can read the original ecu in bdm is easy to clone it....

Here is info for opcom...
