How to: clone Siemens MSDxx (MSD80, MSD81, MSD85, MSD87, MSD85.4) ECUs for BMW SSM vehicles using original Ktag K-suite ecu programmer.
To use this protocol of communication you have to remove and open the ECU. It is a risky operation, to be done with great care and caution to avoid damaging the ECU beyond repair.
After opening the ECU and before proceeding with reading and/or programming, you are strongly advised to reconnect the unit to the vehicle and start the engine, to make sure it still works.
To use this protocol you also need to connect to the ECU connector through a cable, and solder one or more wires to the programming pads.
Incorrect or poorly made connections and solderings may damage the ECU, often beyond repair.
Under no circumstances we shall be liable for any damage caused to the ECU during the opening, due to connections and soldering that do not comply with the instructions provided in this manual. If you are using Ktag clone, you are at your risk.

Notice
When writing the modified file, the checksum of the data may last several minutes, depending on the performances of your computer.
The first time you work on the ECU, before opening the ECU, you need to retrieve the protection password. Follow the instructions provided for each model to connect to the connector.
Retrieve Password
1.Remove the ECU from the vehicle;
2. Connect to the ECU connector to retrieve the password, according to the pinout provided for each model connection instructions:
