Engine 113.99 supercharger from AMG

The engine 113 supercharger from AMG (M113K) is equipped with the ME 2.8.1 fuel injection and ignition system which has already been introduced on AMG models with engine M112K

The abbreviated designation ME 2.8.1 means:
M = Motronic
E = Electronic accelerator pedal
2.8.1 = Version 2.8.1

The ME-SFI [ME] control unit (N3/10) includes the following
^ Injection system
^ Ignition system
^ Emission control
^ Electronic accelerator
^ Cruise control function (up to 2004)
^ Drive authorization system
^ Diagnostic trouble code memory, diagnostic system

The following input signals are processed by the ME-SFI [ME] control unit:
- Boost pressure
- Boost air temperature
- Coolant temperature
- Engine speed and crankshaft position
- Camshaft position
- Throttle valve position
- Air recirculation flap position (in model 230 only as of 07/2002)
- Accelerator pedal position
- O2 sensor signals
- Knock identification
- Oil level, oil temperature and oil quality

Other input signals via the CAN data bus are:
- Vehicle speed
- Drive position detection
- Cruise control detection
- Brake recognition
- Start enable (drive authorization system)
- Crash signal

Depending on equipment and model, individual control units are networked with each other via the CAN data bus (Controller Area Network).
The following control units are responsible for the engine control:
^ Driver-side SAM control unit with fuse and relay module (N10/1) (model 211, 219)
^ Rear SAM control unit with fuse and relay module (N10/2) (model 211, 219)
^ Left front SAM control unit (N10/6) (model 215, 220)
^ Right front SAM control unit (N10/7) (model 215, 220)
^ Driver-side SAM control unit (N10/10) (model 230)
^ Passenger-side SAM control unit (N10/11) (model 230)
^ Rear SAM control unit (N10/8) (model 215, 220, 230)
^ Front signal acquisition and actuation module (SAM) (N10/1) (model 463)
^ Rear signal acquisition and actuation module (SAM) (N10/2) (model 463)
^ ESP control unit (N47-5) (model 219)
^ ESP and BAS control unit (N47-5) (model 463)
^ ESP, SPS [PML] and BAS control unit (N47-5) (except model 219, 463)
^ ME-SFI [ME] control unit (/)N3/10
^ Instrument cluster (A1)
^ ETC [EGS] control unit (/)N15/3
^ Electronic selector lever module control unit (/)N15/5
^ AAC [KLA] control and operating unit (N22)
^ EIS [EZS] control unit (N73)
^ Steering column module (N80)
^ Central gateway control unit (N93) (except model 463)
^ Restraint systems control unit (/)N2/7

The entire test program for engine 113 supercharger AMG is contained in the STAR DIAGNOSIS.
