How to read BCM2, ELV and MEDC17 units

Practical guide to reading dumps: which memory device is inside the unit (EEPROM 95320/95256, internal flash), where it sits on the board, how to connect the programmer (in-circuit or on the bench), how to prepare files for upload and where the wiring points of MEDC17/EDC17, ELV and TCU modules are. Keep the original dump untouched and upload copies — that way the unit can always be flashed back.
