How read look up tables and sensors data in readable format from ICs in ecu?
(OP)
Hi everybody,
As you know ecu look up tables are stored in IC flash
or in micro. When we call these ICs data by any universal
programmers we can see just some codes in that in hex formats.
How can we see what companies programs or look up tables
stored in ECU in some readable formats like any high level programming languages?
How can we understand that which lines number are related to for example
MAP sensor data or O2S or TPS or etc?
Thanks

As for the documented source code itself - it's not generally released to anybody else so any access to that would be by reverse engineering only.

There is really no way to find which parts of cods are related to
which sensors?
so how tuning companies fined sensors data or engine map and
change them in way they want?
I know there are open source ECU data which car manufacturers
release each time they launch new car actually those are capable
to be tuned. So, how tuning companies manage these ECU maps?
Thanks

which sensors?"
Not unless you know someone who can get it for you, either legally or illegally
"so how tuning companies fined sensors data or engine map and change them in way they want?"
See answer above

I really wanted the job, but didn't get it.
Maybe they found someone better at reverse engineering (not likely), or who promised to be less of a pain in the ass (likely).
One thing you can't do is connect some magic tool to a car or any embedded computer and pull out the full source code. It isn't there.
You can spend a lot of money on fancy tools, but you can do a lot with simple tools, and time.
Some hints:
- You do not need to recompile the whole system to change some small part of its behavior.
- The system's behavior may or may not be controlled by lookup tables. I'd say increasingly not, as ECUs have become more adaptive.
- The chips within the ECU may be 'full custom', but they are probably based on a more generic base microcontroller that's available to the general public. ... along with its tool chain.
- Comparative anatomy of ECUs retrieved from junkyards can give you an idea of what changes during customization for a given model. Be sure to record what vehicle the ECU came from, including make/model/options/VIN.
