Engine ECU

This question is for Stef.
Can the car specific information (namely the alarm code) in the engine ECU be removed and virgin information flashed so it would be ready for use?
Thanks
Alan

Thanks Alan, Eric would be the best guy to answer this. I'm not 100% sure in which part of the EEPROM such information is stored in the Motronic ECU and if it's possible to completely erase it. I guess that it won't be that simple

Even if I have not yet tried that, I suspect that copying the content of the parameters small EEPROM (95040) from a LH ECU into the ECU you want to make working, could be enough.
A LH ECU, which has never been installed in the RH position, should not contain any immo data. So basically, cloning such an ECU, should make the clone usable again on any car, as any LH ECU. Doing that way, you would avoid the pain to find the immo data, to clear them and to correct the checksum bytes.
To be validated, though ...

Well, Alan, finally not sure it is so easy. Read this one :

Still some things to discover about these ECUs ...

I tried, after coping RH and confirming the flashed eeprom data matched the original-bit for bit, it failed to run on all 8 cylinders.


the car ran on the 4cyl of the left bank only. then removed the ECU and download the eeprom again and found most of the data had been changed


beat by Bosch- I gave up, but if anyone has any better ideas, I would try again.
