The MotorWerk additional module for M157 and M177

The MotorWerk additional module for M157 and M177


Every time the manufacturers make it more and more complicated and harder to enter into the factory engine control unit ECU to achieve reasonable and more stable power to the engines.


LOEWENSTEIN looks far into the future and already decided in the past to invest intensively in the development of additional modules with its own brand MotorWerk and thus makes the company stand up clearly from the competitors!


This advanced and future-oriented technology of modifying the engine electronics without interfering in the standard motor control unit ECU has been already brought into action sucessfully by LOEWENSTEIN under its highest quality standards his own supercharger systems and proved its perfect function and the resulting stability of power increase.

Performance with German TÜV and Vmax uprating up to 330 km/h

The Loewenstein 63 AMG additional engine performance with German TÜV certificate gives the V8 twin-turbocharged direct injection engine from Mercedes up to 700 HP and enormous 1000 Nm of torque, depending on the output power, or the standard engine/vehicle model.


The LM63BT-700 performance module is even much easier to install than our diesel modules. This Plug&Play system comes with a detailed and pictured installation guide and allows installation or even rear armor in less than 30 minutes.


There is constant communication between the factory engine electronics and the MotorWerk CGI module. With its own processor there is a quite extensive control of multiple sensors, acknowledgment systems and parameters to guarantee one of the most stable performance upgrades on the market. Any safety-related limit values and protection parameters are obviously preserved and taken into account, since the MotorWerk module does not interfere the factory engine control unit!


However, even more protective functions are built in the additional module through the factory CAN-Bus data connection. The digital signals of the air mass meter, as well as more information is read via the CAN-Bus and processed immediately.


The system


    The LOEWENSTEIN module is 100% Made in Germany and continues the demanding standards of the automotive industry.

    The connectors and crimps are original automotive products and are manufactured by machine. The cable isolation resists thermal loads up to 150 C° and the module housing is waterproof.

The extra power does not generate immediately elevated CO² emissions and this is reflected in the fuel consumption. A guiding CO²-system guarantees prescribed standard values CO² emissions.


Thus, the factory set emissions classification remains unchanged!

Vmax uprating

We also offer the Vmax module, which is installed in the interior and clamped to the associated CAN-Bus system.

Depending on the vehicle, the fitting time is approx. 45 minutes. 

The Vmax can be uprated up to 330 km/h. To date, no other tuner has still managed to use an additional module with the simple Plug&Play system to change the Vmax, not even at the Mercedes 4Matic.
