Link G4X plug-in Toyota JZX100 Mark II 1JZ VVTi

Description

Link Part #JZX100 (SKU: 232-4000)

 

The Link G4X range of engine management systems builds upon the previous G4+ ECUs by featuring an all new micro-processor, an upgraded communications chip and expanded data logging. These improvements allow for a more responsive and accurate tune, much faster download speeds and far greater internal data logging capacity.

 

The Link G4X range of engine management systems are well known for delivering class-leading performance without sacrificing factory levels of drivability. The G4X plug-in ECUs are designed to be the most complete plug-in solution yet.

 

This Toyota JZX100 Mark II plug-in ECU will save you time and money as they will plug straight into your vehicle’s original wiring loom without the need for messy adapter harnesses. It replaces the original circuit board inside the factory ECU enclosure and mounts using the factory brackets.  It is suitable for 1JZ VVTi powered X100 Mark II’s in either naturally aspirated (NA) or turbocharged configurations using a manual transmission as detailed below. Automatics are not supported.

 

  • Toyota Mark II – 1996-2000 X100 models with 1JZ VVTi engines (manual transmission only)

 

Once the installation is complete, the Link G4X allows a good tuner to achieve an optimal state of tune to get the most out of any combination of modifications.

 

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 factory air flow meter is no longer required. This ECU can also be set up to control boost electronically with in-cabin adjustment. This eliminates the need to purchase  a separate electronic boost control system.

 

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

  • MAP sensor – This ECU comes with an on-board 7.0Bar (up to 87psi boost) MAP sensor. Alternatively, an external MAP sensor can be connected to the existing wiring that was previously used for the mass air flow sensor or connected to one of the analog inputs of the G4X’s expansion connector using the XS Loom (sold separately)
  • Inlet Air Temp Sensor (IAT) –  For best results we recommend an IAT sensor to be fitted to the intercooler/intake pipe just prior to the plenum entrance (these are available from NZEFI). This may use the existing IAT wiring or connect to the expansion connector of the ECU.
  • Injectors -The Link G4X plug in is NOT designed to be used with low impedance injectors. Fortunately, the Toyota Mark II X100  is 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. These are available separately.

 

Extra sensor inputs

The expansion connectors on the Link G4X board is provided to allow the easy connection of additional ECU inputs. The expansion connectors provides the following:

Expansion Connector 1:

  • Sensor Ground
  • 2 Analogue Inputs
  • 5V Supply
  • 2 Digital Inputs
  • 1 Auxiliary Injector Output (Aux Inj 8)
  • 1 Analogue Temperature Input

Expansion Connector 2:

  • 1 Analogue Temperature Input
  • 2 Digital Inputs
  • 3 Auxiliary Ignition Outputs (Aux Ign 4, 5, 6)
  • 2 Analogue 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.

E-throttle Connector:

  • Sensor Ground
  • 5V Supply
  • 4 Analogue Inputs
  • 2 Auxiliary Outputs
