Hi All,

I want to replace a faulty Siemens ECU (Part no A 111 153 27 78) with a similar ECU from the junk yard.

Can anybody give me an idea how to renew the Siemens ECU. This ECU has only a 29F400BB flash chip and no EEPROM. The Bosch ecu's is no problem as they work with a eeprom or serial eprom. I need the address and data to change on the 29F400BB Flash to enable the Star System to adapt or renew the ECU to the new car.
