911 GT3 Cup (991 II) 
MY 2018 

6.4.1

 

DME control unit 

 

Voltage peaks 

Damage to the control unit 

 

The control unit must be disconnected from 
the wiring harness before welding work is 
carried out. 

 

The battery must be disconnected before 
the control unit is removed. 

The Bosch MS 4.6 NG control unit is installed in the rear section of the passenger side. 

The wiring harness leads through an electrical connection directly to the engine. The 
911 GT3 Cup (991 II) is equipped with the engine control unit Bosch MS 4.6 NG that 

has  been  developed  specifically  for  use  in  motorsports.  The  controller  can  be 

programmed using a special software and also offers the possibility of error diagnosis. 

Device programming is carried out exclusively at Porsche Motorsport. The online Error 

diagnosis functionality is only available for the engineers of Porsche AG. If an engine 

overhaul is to be performed at Porsche Motorsport, the corresponding engine control 

unit has to be sent with the engine. On one hand, this ensures safe operation on the 

engine test bench; on the other hand, the engine lifetime counter in the ECU can be 
reset immediately after overhauling the engine. 

 

The MS 4.6 NG provides the following functions: 

 

Cylinder bank-selective lambda control 

 

Pit lane speed limiter 

 

Ignition cut for power shift with sequential gearbox 

 

Asymmetric injection and ignition control 

 

Knock control 

 

Electronic throttle system and blipper function 

 

DFI control 

 

Control of intake and exhaust camshaft adjustment
