The MS 4 Sport is an engine management system forhigh performance engines up to 8 cylinders. The system contains 8 ignition drivers for external powerstages and 8 independent injection power stages. Two
independent wide range lambda circuits allow lambda
closed loop engine control. There are also versions for
Turbo and GDI engines as well as for Turbo GDI engines available. Various engine parameters can bemeasured with different input channels and transferred via CAN interface to an optional data logger.
