First:
Read and extract the original file from the ECU.
Depending on the ECU type it can be done, for example, with Kess V2 or K-tag.
To extract the original file, some ECUs have to be opened and others not. The connection processes, and unblocking (in some cases), are explained in the Ksuite.
In my case it was not necessary to open the ECU, I did it through the OBD2 port with the Kess V2. (easily
)
In my case, the Ksuite 2.47 did not work under the f-Windows10, but it did perfectly under Windows7. I bought the Ksuite 2.47 from aliexpress.

Second:
Edit the original file.
This can be done with programs for experts, or with a Hexadecimal editor. HxD is a good editor, it can be downloaded
for free.
And now it's as easy as changing the values where it corresponds. In my case, a single Byte (of 2MB
). Its new HEX value enable two Bits.
Save the edited file.

Third:
Rewrite the ECU with the edited file.
I did it with Kess V2 through the OBD2 port. (easily
)
I think it took me 3-6 minutes to rewrite the ECU. RED Kess V2 is a beast.
It works exactly the same as it does in the 6R WRC. .... like a charm.
lol) we sell it here in the forum.
