Design

The housing of the ME-SFI [ME] control unit consists of aluminum and is designed as a shell concept unitary housing. The housing contains measuring and control electronics for the engine control.

Task

The ME-SFI [ME] control unit controls the engine control ME 9.7 AMG according to input signals.

The abbreviated designation "ME 9.7 AMG" means:

M = M otronic

E = E lectronic accelerator pedal

9.7 = Version 9.7

AMG = AMG specific hardware and software

Function

The following systems are controlled and coordinated by the ME-SFI [ME] control unit:

Ignition system
Injection system
Idle speed control
Electronic accelerator
Torque interface
Alternator interface (LIN)
Fuel evaporation control system
Heat management
Starter control
Immobilizer and drive authorization system (FBS 3)
Diagnosis and fault storage
Emission control

Dependent on the equipment and model, vehicle control units are networked with the ME-SFI [ME] control unit via the CAN data bus (Controller Area Network). They can send data to the ME-SFI [ME] control unit depending on the function or receive data from the MESFI [ME] control unit.

Diagnosis

For diagnostic purposes individual function can be actuated in a targeted way using STAR DIAGNOSIS.

Correction programming of individual performance maps and variant coding is also possible using STAR DIAGNOSIS.

The engine control in ME-SFI [ME] control unit is flashable. The software required to program the control units is provided on the STAR DIAGNOSIS DAS Update DVD.
