Sell BDM MPC555/6

The ECU must be removed from the car and is programmed by special spring contacts without soldering on the circuit board. This method is used for example if a car has no connection from the OBD connector to the ECU or for very new ECU versions. The best tool for this is the BDM 100 Which way of programming is used, depends on manufacturer, model, year and the ECU type in the car. Generally we use the “easiest” way of programming. So if a car can be programmed by the OBD port, we will do it this way. After the security entries for the OBD2 programming get more and more difficult, a new possibility has come up for chiptuning of ECUs with Motorola MPC555 - 565. This generation of Motorola processors contain 448KB - 1MB Flash memory. That memory cannot be read and programmed with an eprom programmer. Therfore it is possible over the so called BDM interface, which must be implemented on every ECU board. For that purpose there are mostly 10 solder pads on the PCB. Alternative there are ECUs with 12 or 14 solder pads, which can be supplied with operating voltage over these pads.
