Link G4X Plug and Play ECU for Nissan 64-pin CA18DET and Zenki S14 SR20DET

Product SKU: LNK NS15X

Free yourself from the constraints of the factory ECU. The Link G4X S13Link NS15X Plug In fits the Nissan SR20DET with 64 pin. The ECU PCB fits discretely inside the original factory enclosure and mounts using the factory brackets. 

Installation of Link's ECU is a breeze with no alteration of the factory wiring loom required. A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches. 

This plug in has also been successfully used on some other SR20DE and SR20DET engines that use a 64-pin blue plug ECU.  It will NOT work on any models that use a larger 76 pin blue plug ECU (S13 CA18DET and S14 "Zenki").  

All Link G4X plug-in ECUs come with a base map. While these maps are designed to help save time for you and your tuner, it is essential that these are used simply as a starting point for further tuning.

The vehicle’s original sensors & actuators are used except for the following exceptions:

  • MAP sensor – This ECU comes with an on-board 4.0Bar (up to 44psi boost) MAP sensor. If higher boost pressures are required then an external MAP sensor may be used and connected to one of the analog inputs of the G4X’s expansion connector using the XS Loom (sold separately). The airflow meter is not required.
  • Inlet Air Temp sensor (IAT) – An appropriate IAT sensor (sold separately) should be fitted just prior to the throttle body. These can be connected to the expansion connector of the ECU using the XS Loom (sold separately). 
  • Boost control – The factory boost solenoid wiring on SR20DET S14a Zenki and S15 may used, however an appropriate boost solenoid (sold separately) must be used. 
  • Injectors – The Link G4X plug in is NOT designed to be used with low impedance injectors. All Silvia models (with the exception of CA18 models) are factory fitted with high impedance injectors so no change is required. However if aftermarket low impedance injectors have been fitted then the correct ballast resistors MUST be fitted (sold separately). GTi-R engines have low impedance injectors from factory, but they already have ballast resistors. If the GTi-R injectors are replaced with high impedance injectors then the factory ballast resistor pack must be removed.

Extra sensor inputs

The expansion connectors on the Link G4X board is provided to allow the easy connection of additional ECU inputs. These may be used for functions such as driver adjustable boost control, switchable fuel/ignition maps, wideband lambda input, external MAP sensor, fuel pressure and oil temp/pressure.
