MG1/MD1 replace ISN by eeprom

How to replace MG1/MD1 ISN by eeprom DUMP

1. Read original MG1/MD1 eeprom, and used MG1/MD1 eeprom.
2. After read find on original MG1/MD1 ISN (DME+EGS + (some cases EME))

Example
Original MG1CS003 Detect ISN!

Blue are – EGS ISN
Red are – DME ISN
Also DME+ EGS ISN (16byte + 16 byte)
P.S "CHK" on the front and back
How to detect ISN?
You can use my “ECU ISN” software.
Free download on www.bmw-az.info
Some cases its can detect right buth some cases not.

Example
Correct designation V2.4

Wrong definition 2.5

Logically, it is repeated twice.
More repeats are wrong.
Logically, it is clear
It will ensure that the program is set correctly over time!!!

Now we read used MG1/MD1 eeprom and detect ISN

Blue are – EGS ISN
Red are – DME ISN

!!! Special mention !!!

But use the same model brains.
Otherwise "range will vary"
MG1CS003 = MG1CS003
MG1CS201 = MG1CS201
ISN logic is very simple.
Repeated twice 16+16 =32 BYTE
0000 or FFFF are excluded here.
Visually it is possible to determine. If you have difficulty in determining, use "2nd hand programs".
There can be 4 or more rows between the first 32 Bytes (ISN) and the second 32 Bytes (ISN). Each line is 16 bytes (32 characters)

3. Replace İSN!

From “ORI” eeprom, swap the lines to “USED” eeprom!
Consider spacing carefully. You can take an extra row "up-down" if needed.
Look carefully, do not make "crazy" movements!
Put it in the car and do "reflash" and "Coding" with ESYS.
Next time we will talk about "engine working hours reset" and changing ISN with "Tool32".
