Is it possible to clone saab ecu

[scoot]

Hi all i have a saab 2.0t year 03 with a faulty ecu i have a used one that i would like to clone i think its a trionic ecu the numbers are 55352688 there is no manufacturers name . What programmer do i use or can i just swap eeprom many thanks in advance scoot

[smokey08]

Immo is in the flash so you can just swap that over.

[scoot]

Thanks smokey08 but it dident work immo problem must be in microprosessor

What did you use to read/write?

[scoot]

I dident read /write cos i dont know what to use i just changed flash chip thanks for reply

[soxten]

Do this work?
I have same problem and need to know if this work.

Here is some piture on ECU
I have Flash AM29BL802CB?

I see BDM port?
Simens?

[soxten]

Please someone?

[Listek22]

It's Siemens Tronic 8. BDM beside flash.
214897

[soxten]

Thx, but which tool for bdm reading?

[Listek22]

I would check BDM100 first

[soxten]

BDM100 and CMD software has not Tronic 8?
Could I use Simens BMW?

FGtech has Tronic 8 but i don`t have that tool...

But if I change Flash it must work?... Immo and vin is in flash.

If is mcp5xx you can read with xprog.

[easytech]

You have to use optican or trionicsuite (goolge it) for BDM reading.
It have a 68f3xx processor.
Or just swap the BL802.

[soxten]

Yeees!
Did it on BDM :)

But! Do this work?
Have someone make it work?
some people say the car start but runs bad?

[soxten]

In T8suite i see information as VIN but I can't find Immo code?
Do someone know were immo code is located in .bin file?

[soxten]

Some people say:
"You can use another T8 ECU by using BDM to copy the original BIN file including VIN and IMMO. BUT, you need to reset the adaption data block as well otherwise your engine won't run properly.
We use the CAN bootloader to reset the adaptation data block for us. The FLASHing part probably isn't necessary but we don't know how to reset adaption without also FLASHing http://forum.ecuproject.com/images/smilies/icon_rolleyes.gif. It may be possible to reset the adaption block using a Tech2 tool instead of CAN FLASHing the BIN file again, but I'm not sure"

How to reset adaption data block?
Is this in MCU?

[zoro1]

Is there eeprom ?If yes I think adaptacion mast be there

[soxten]

Zoro1: please explain more.
eeprom?
there is 5 eeprom on motherboard.
do I need to clone someone or?

[soxten]

Is it posible to read MCU?

[zoro1]

5 eeproms?are you shure?what type are they?on audi coding is in on eeeprom immo in other,vloser to MCU is immo eeprom.

i have try my BDM and didint read,i know the orginal BDM is reding that ECU,i have same problem :P my car running when gets hots stops :P

[infinet]

Me too. 2003 model. Is there someone in the UK who can reprogram my ECU? Looks like the kit needed to do it yourself is costly.
