Hello mates,
Can anyone tell me how to read this ECU in BDM mode?
Or where are located BDM pads on this ECU.
I want to clone it.

i think it is on back side

i also think the same... but it is very hard to get on the back side.
i think it is glue like EDC7UC31 from Iveco/MAN.

maybe somebody has some information where are located simillar pins on this side.

Tuning by obd

13th January, 2013, 12:56 PM
just by OBD reader or try to rehot and carefully open it

13th January, 2013, 12:57 PM
yes. i know that tuning, dpf off, egr... etc... by OBD, BUT to Clone it??
or if i want to tune it and car is not here... do you have pin connection?
i have byteshooter master, fg tech2, mpps... etc.

thanks emiliogsm... but i cannot permit to damage such ECU. it cost 1300 euro.

:) i know that but you have no other way to clone it
i am open alot a ecu like this and its not so hard .
Just use a BGA rework station on 150 degrece and rehot back side .

BDM is in another side of pbc, like emilio said the best solution to remove pcb without demage is heat and very carefully to dont bend the pcb. The pinout you can find in wiki obdtuning.

BGA rework station not have, just one cheap hot air gun.

i will try to do this job..

13th January, 2013, 03:26 PM
just do it slowly and careful and you will be fine :)

13th January, 2013, 04:59 PM
i agree slowly and carefully ... not a problem

13th January, 2013, 10:39 PM
check with this conection

14th January, 2013, 12:52 AM
it is not good. that's for sprinter/vito... not for CP36. thanks anyway

i?m not sure, but i think your ECU don?t have eprom, Eprom is emulated in flash, in this case you can read by obd and clone if have another with same part number.

I can confirm that's on the back (EEPROM and BDM port) It is hard to separate from the bottom heat sink thou.

Becarefull not to damage or chip out surface resistors there are tons of them :s
