Product Description

The Link G4+ range of engine management systems are already well known for delivering class-leading performance without sacrificing factory levels of drivability.

 

Link Part #G4+K

 

The Link G4+ Kurofune shares the same ECU header connector pinout as the HKS F-CON V Pro V2 (silver) and V3 (gold) engine management systems. This allows the G4+ Kurofune to be fitted to any vehicle with an existing HKS F-CON V Pro ECU with no, or very little wiring required.

 

The HKS F-CON V Pro was originally designed as a way of taking full control over fuel and ignition while leaving the factory ECU to perform more mundane tasks like control of the fuel pump, fan, idle speed control etc.  Installation was performed by using one of the many adaptor harnesses that HKS offered. Essentially these adaptor harnesses directed fuel and ignition wiring to the HKS ECU as well as sharing sensor wiring between both the factory ECU and the HKS ECU.  The F-Con V Pro ECUs also had analogue outputs to provide a simulated air flow meter signal to factory ECUs that originally had an analog based air flow meter (AFM). This feature allowed the factory AFM to be removed without upsetting the factory ECU. While HKS’s ECU could get the the job done for most of the 1990s applications that it was designed for, but it also had quite a few limitations.

 

  • HKS’s PowerWriter Tuning software was not freely available
  • All models from Ver2.0 to V3.3 did not have boost control – despite the considerable cost of this ECU, HKS was greedy enough to think that you should still need to buy one of their stand-alone electronic boost controllers as well.
  • All models from Ver2.0 to V3.3 did not have built in continuously variable cam control – this time HKS thought you should either leave the cam control to the factory ECU or buy an HKS VALCON which was yet another one of their controllers. V3.3 could at least integrate with the separate VALCON unit, but it could still not control control the cam(s) directly.
  • All models from Ver2.0 to Ver3.3 did not have built in knock control hardware – yes HKS wanted to you purchase yet another controller – this time it was the HKS A/F Knock Amp.
  • The PC tuning software was slow and cumbersome
  • The ECU based logging was quite limited
  • No ethanol (flex fuel) support
  • Firmware updates could not be completed by the end user – ECUs would need to be sent back to HKS to be upgraded for a fee
  • Many other limitations compared to the the Link G4+ platform

 

With the Link G4+ Korofune,  existing HKS adaptor harnesses can be retained, but these restrictions can be easily eliminated.  The vastly superior Link tuning software ‘PCLink’ is also available for free and the same version of software can easily be switched between either English and Japanese language.

 

The Link G4+ Kurofune has the following inputs and outputs:

  • 8 Injector Drives
  • 8 Ignition Drives
  • 10 Auxiliary Outputs (Fan, Boost control, idle speed control, etc.)
  • 4 Analogue Outputs (For emulating signals such as airflow, pressure, O2 or temperature)
  • 9 User-configurable Analog Inputs (MAP sensor, wide-band O2, oil pressure, boost adjust knob, etc.)
  • 3 User-configurable Temperature Inputs
  • 10 User-configurable Digital Inputs
  • 2 Dedicated trigger inputs
  • 2 x Knock Inputs
  • 1 CAN bus
