hi, some owner of bmw e34 520i can confirm if the eeprom has this reference in the DME
1267357027??
I have bmw e36 325i non vanos and I think they share the same eeprom
I answer myself, the reference of the software epprom is the same in m50b25 and m50b20
1267357027 use 325i and 525i also 320i and 520i the same.
They use DME Bosch Motronic 3.1 0261200402 everyone non vanos.
Some also use 1267357098, but practically the same uf is the same

The DME in my E34 520i M50B20 is a Siemens MS40.0 5wk9 003 not a Bosche if that helps any
