Fiat BSI ,hacks ,configuration request

[duemilasedici]

Hi, did you extract some more information from your body computer?

I'm interested in adding VDC on an Alfa 147, and investigating around car configuration in body computer...

I know the CAN bus must "accept" the steering sensor I should add for the VDC, and also recognize the new ABS/ASR/VDC module in place of the old ABS/ESR one. I guess this can be achieved through the 55 bytes of "car configuration" Proxy File... But I would like to know more...

Thank you!
Marco

Hi, this is all that I have found after an hard search on google...


It is about a Stilo Body Computer (that should be the same, or very similar, to alfa 147), and the topic was about adding the cruise control...



NQS Configuration. #44
Bit 0 = 0/1 means gas discharge lamp disabled/enabled
Bit 1 = 0/1 means over-speed warning disabled/enabled
Bit 2 = 0/1 means ODO units change disabled/enabled
Bit 3 = 0/1 means auto-lamps not fitted/fitted
Bit 4 = 0/1 means Cruise control absent/present
Bit 5 = 0/1 means transmission type manual/auto
Bit 6 = 0/1 means oil information request/not request
Bit 7 not used / reserved

NQS configuration is about the dashboard node. Looking at your dump, it looks like ODOmeter units are changed (and it looks ok, they should be miles...), and that auto-lamps are fitted. Can you confirm this?

I need more extended information on proxy file, in order to reprogram the NFR (brakes/abs/asr/vdc) configuration inside the body computer and NOT get the "wrong CAN configuration" error from ABS ECU once fitted. The car is a 2001 Alfa 147.

Furthermore, I guess I should install the steering sensor (which is also connected to CAN), and so properly code it in the same proxy file inside the body computer...

Can someone help me...?

unfortunately i can't answer your questions because this dump is from a UK bodycomputer i bought on Ebay to do some chip reading experiments , i know nothing about the car it belonged to...

[yellowstilo]

do you know where you found this info about the meaning of byte # 44 of the Fiat Stilo Proxy file?
Or do you know what search subject you used to find this info?
I guess the author will have a Fiat document containing the meaning of all bits of the Proxy file - i would be very pleased if i could request this info to be able to alter the configuration contents of my Stilo!

for Fiat Stilo :
byte 53 of Proxy file :
bit 0-3 = NFR variant (braking node) > value:
0= absent
1= abs
2= asr
3= vdc
4= tc

value 5-15 =reserved.


Steering angle node = NAS
byte 27 / bit 4 set to 1 for NAS present.
Yaw rate sensor = NYL
byte 27 / bit 7 set to 1 for NYL present.

(bit 7 = MSB, bit 0 = LSB)

hope this helps,
good luck!

here is a second file of the eeprom + full BSI processor (Motorola 912DG128a) of a Dutch Fiat Stilo - when you compare them to the first files you can see where the differences are....

[yellowstilo]

because i did not want to solder the pins on the 912DG128 processor of the Fiat Stilo bodycomputer i searched for some soldering pads on the back of the pcb to connect UPA (or other) programmer:

[szwajcarek]

Hi yellowstilo
Did you manage to read it with UPA or did you use other programmer ?

BR

[yellowstilo]

i used UPA, works fine !

[bursuc]

I got one fiat 1.8 2011 benzin.

BCM is BURN.
Need to swap with a second hand one.
Need some advice.
What i need to change ? What i need to read...

Thak you : more info here :

Ciao gert, do you need proxi data of wich car? 147 or stilo or ....
I have all of that data. Let me know and I will upload them......
ciao
And if you need to change some data, send me the body proxi and I will change it.
About immobilizer data, You need to unlock memory, and after this you can change and read immobilizer data, keys trasponder, radiofrequency as you wrote you can read proxi data sending to the body computer 21 23 ( 21 is read command and 23 is proxi location ) but if you need toread immo data you have to send 21 20 , but before read this data you must unlock memory otherwise bodycomputer will send you back negative response.......
by the way if you need detailed info, I hope I can help you.
ciao

Hallo Beppe

Thanks for your interesting info.
Can you provide this useful information about proxi data and so on.
Will be very interesting to modify data to add some function, like fog light and so on.
Can you adapt a used remote only editing immo data?
Thank you
