It is proprietary information. Your choices are either to remove the
engine ECU completely and install a programmable aftermarket controller,
or to reverse-engineer the ECU yourself.

There are some more common ECU modules out there which have been reverse
engineered pretty well by the aftermarket tuner community, but those guys
are also not generally very talkative.

Ok, I'm a bit familiar with the fuel dispensing technologies and as
far as I know,
In AVI devices the fuel tank ring reads the
odometer and transmits it to the system (via Wi-Fi or RFID).
If I'm not mistaken AVI devices could be integrate in almost any model
of car...
So from where do they receive the odometer information?

Probably from the computer that controls the instruments, which usually gets
a pulse from transmission which it derives speed and distance from.

Many of the newer cars have data busses rather than individual lines going
from one black box to another. This means you can add a device to the data
buss and extract data from all the different computers throughout the vehicle.
