Fiat BSI ,hacks ,configuration request

**armpower** · 15th February, 2010, 07:09 PM

Hallo

I've a question for you all.
Anyone have an idea where are located the info regarding Can configuration of installed module (Fohg lights,Steering.AC control,) in Fiat BSI?
Possibly in the same eprom where are stored im*o information?
Anyone have tried to hack this configuration?
Like for example, adding fog light and eps steering in can configuration?
Any idea or info are well appreciated?

Thank you very much.

Any idea?

Anyone have tried hacking this BSI modules?

actia multidiag latest version likes bsi.... try it

I meant Fiat Body computer module hacking.
Probably Multidiag is good for PSA group' BSI.
Actually, the only diagnostic solution for re-configuring body computer modules is Accini' Leonardo.
I'm searching some info to do this job hacking the module inside, aka changing eprom contents.
Anyone is able to do this?

replace 93c66.

**armpower** · 16th February, 2010, 08:43 PM

Ok.
But more precisely:
In which location of eprom dump you can find the information regarding configuration of body computer module?
For example:
If anyone want to add the fog light in eprom in which location are written this info?

**odyseus7** · 16th February, 2010, 08:51 PM

93c66 or HC912DG128/256.

Only solution for your,,hack,, is to take LEONARDO and make change and every time read eeprom.
But..............
Leonardo not make like you read or some tell you.
I hear to much thing , and when finaly i get leonardo ...............
To much money for .............nothing.
And in 70% of car update coming.
All diag make config in new type body.
In older type cant make config like you want.

on the Fiat Stilo the configuration of the vehicle can be read from the body computer by command hex 21-hex 23 (read local id, id 23 = config. table)
50 kbps / 11 bits can , id of bodycomputer is 7C0, hex adress 04.
This returns 55 bytes but decoding of the info will be difficult...
I don't know in which chip this info is stored.

EDIT: INFO STORED IN EEPROM part OF HC912DG128 / 800 - FFF (000-7FF in eeprom read)

hello,
I have a Stilo with the turning lights issue(works nonstop).
Replacing the Body Computer all this faults is gone,but car not start.
How can be adapted the keys and the configuration of the vehicle on the used Body computer?
Thank you.

did you order a replacement body computer at the Fiat dealer (which will be a 100% copy of your current body computer) or did you buy a second-hand one?
In case of a used one you could swap the microprocessor inside which holds the data and configuration of your car (probably 912DG128 , but other manufacturer number printed on it...)
It's a 112 pins chip, only a DIY job when you have good soldering skills and equipment.
Other possiblity is read old chip and reprogram new one with this file...

hello,
it will be a second-hand body computer.
I can read only EEPROM with UPA-USB from 912DG128 it is enogh to swap the configuration and keys?

**yellowstilo** · 24th October, 2010, 08:43 PM

i would copy and reprogram the whole contents of the chip to be sure - in that case i guess everything will work as before (assuming the fault is caused outside the processor...)
I was able to read the whole contents of the chip - did not yet try to reprogram it...

i read the contents of the 912DG128A processor inside the Fiat Stilo Marelli 2 body computer , both the eeprom and full chip.

if someone could give some hints about the location of the pin code or other important information that would be great , i just want to know more about these Fiat Stilo Marelli 2 body computers...

**yellowstilo** · 14th November, 2010, 09:22 PM

i found some data in the eeprom file of the 912DG128A inside the body computer of the fiat Stilo:

total size 000-7ff
3 identical data blocks: 000-20D / 20E-41B / 41C-629 (526 bytes each)
Proxy file (= configuration of car) 62A-660 (55 bytes)
fiat drawing nr. 77C-786 (11 bytes / 3 blanks)
fiat hardw. nr. 787-791 (11 bytes)
Fiat ecu hw. vers. 792 (1 byte)
fiat homolog.nr. 793-798 (6 bytes)
fiat iso code 799-79D (5 bytes)
date of downl./prod.79E-7A1 (4 bytes)

i will try to find more info, especially i'm very interested to find the location of the PIN data , any help is appreciated!
