Another method of ecu remapping on vehicles fitted with ecu that contains a Motorola MPC555 – 565 processors is via a BDM Module. This BDM module can read and program 3 data areas on the ecu the processor, eprom and eeprom it is a very safe way of chiptuning ECU’s giving the user a full back up copy of ecu data.
the bdm module also comes in very handy for recovering ecu’s after a bad flash via obd ecu remapping here at mas performance we keep the bdm module in our tool box not only for this reason but also for when an ecu cannot be read though the obd socket so ecu remapping can always be done.
