BDM 100 requires the ECU to be open, "on the bench", as the reading/programming operations are realized by linking a flat cable to specific area the ECU (the tool, on the other side, is linked to the USB port of a computer).

BDM 100 allows also to create perfect copies of the whole software of an ECU (after having read the original ECU software).

The software allows to read and program the WHOLE ECU content of:
29BL802 SSOP eprom file (or ROM memory with maps if eprom physically not present);
MOTOROLA MPC5xx Processor file;
Serial Eprom content.
Please note that even in the case of the ECU blocking, due to the wrong checksum recalculation, the ECU can always be reprogrammed and then retrieved (if the original software has been previously stored).
