    Dear Euroscan:

    I have the following problem:

    I need to change the ECU H?brida M1.5.5 for an Alfa Romeo 156 and i don't know the Pin Code because the immo doesn't have a serial memory. Only come a Microprocessor without a serial memory- The Micro has 44 pines and i do not know which is the pinout for reading it.

    I need a dump for the ECU h?brida M1.5.5 for Alfa Romeo with Immo OFF in order to write the ECU with galletto.

    If you have not the dump with IMMO OFF, I would like to know:

    - ?Do you have some dump for 24C16 for this ECU?
    Would you please post it?

    - Do you know if the Pin Code is in the 24C16 too? ?In which part (hex address)?.

    I need to know how tor read the Pin Code on the ImmoBox which doesn?t have serial memory.

    Or I need a dump for the ECU with Immo OFF in order to write the ECU with galletto.

    Thank on advance.

    I found a immo off file for the ME3.1 but I'm not sure how to use it. I've written it to the ECU but it's still coded.

    Does anyone know how to immo off a ME3.1? Thanks in advance!

    Here is a photo of the ECU.




    This is the chip I found and the pinout I think is correct. Please check and correct me if I'm wrong.

    - make boot mode, SDA to gnd.
    - upload immo-off file
    - reconnect SDa pin.
    - upload original file.
    - i have yet to see this procedure

    Car: Alfa Romeo 156 2.0TS Selespeed (-00)
    ECU type: Bosch Motronic ME3.1
    ECU number: 0261204949
    Software number: 1277356500

    Thank you very much for any help!

    Hi

    Do you know the location of SDA and SCL pads for a ME3.11?




    Thanks

    Anyway, my problem was the Idle control adaptive value which was very high (2.02) because of faulty throttle body earlier. After throttle was changed, this value remained the same and idling was very high (>2000rpm) and oscillating sometimes.

    I drove maybe 5000km without any change and finally changed some other faulty parts and this value started to decrease automatically. Faulty parts were gas pedal (another potentiometer signal not stable) and thermostat. My conclusion is that this value is not automatically adjusted if the engine controller is not in a normal state (fault code or temperature below regular).

    For a while my idling was ok but now it's very stable 0rpm because of broken immo.
    I know this is few years old but do you still have the document for reseting adaptive value for throttle or remember the procedure. Alfa Romeo 156 2.0 selespeed Bosch Motronic 3.1 electric throttle body.
    Thanks

    hi guys, i'm in the same situation. after cleaning the throttle body the idle oscillates between 1500 and 2000 rpm. the only solution is immo off of the ecu?
