Engine Management (MSV70): Notes

There are several new innovations introduced with the new MSV70 engine management system. The most obvious innovation is the addition of Valvetronic II to the six-cylinder engine line. This is the first use of Valvetronic on the BMW six-cylinder.

The MSV70 engine management system is responsible for the following tasks:

• Ignition control
• Injection control
• VALVETRONIC II control
• Control of "Weight Optimized" double VANOS
• Engine temperature control (characteristic map control of engine thermostat)
• Electric coolant pump control (Heat Management System)
• Knock control
• Lambda control
• Fuel tank ventilation control
• Load request to air conditioning control unit for A/C compressor
• Activation of 3-stage differentiated intake manifold (DISA)
• Electric fuel pump module control (EKP)
• Cruise control
• Alternator control
• Heated crankcase ventilation
• Electronic oil condition monitoring and oil level monitoring
• Energy management (IBS)
• Monitoring of input and output signals
• Calculation of substitute signals and failsafe functions
• Self-diagnosis

The engine management system on the N52 engine complies with OBD regulations and meets the ULEV II requirements for 2006.
