Both Foxflash and OBDSTAR DC706 programmer will read and write Mercedes Benz MED17.7.3.1 engine ECU on bench mode.

With Foxflash:

You can do a full read (read all) of this ecu. On read all you can write all without checksum, and restore like it was before.
But for modification, absolutly not needed to flash all, just write flash.

Write only internal flash and external flash, no write eeprom.

With OBDSTAR DC706
