0261203660 (M1.7.3) DME (ECU)

[speedy100]

Hello,
BMW Series E36 316-318 use a Bosh ECU no. 0261203660 (M1.7.3) that is not possible as far as I know to Immo Off.
In case of ECU Swap with a used one does anybody know were the immo is programmed in? The 27C512 that is on board does not include such info so an other chip must contain that info. Unfortunately I do not recognize any other EEPROM on this.
Any ideas were could it be hidden... ?

Thank You for Your time

The immo (ISN) is stored in B58542 chip.

Thanks again but by swapping the B58542 (27C512) it does not work. That means that either it does not contain the immo info or an other chip is also involved... This is the problem with ...660 ECU.
Any other ideas please?

After swapping chip you can do EWS-DME alignment and it should work. It DOES contain immo info (ISN), in fact i have tested it for this particular ECU.
