Engine Management

HKS F-CON iS Logo F-CON iS can control the latest advanced engines. Just connect to a stock ECU with a vehicle specified harness without modification. HKS "F-CON iS" is a piggy-back ECU for fuel and ignition management as well as new features.

HKS F-Con iS Functions for fuel and ignition controls are inherited from the previous model F-CON SZ. In addition to it, function to collect OBD II diagnosis data was added for correction of setting due to stock close-loop correction values when intake/exhaust parts are upgraded or boost level setting is changed.

* Editing the control data or settings must be performed by the F-CON Dealer.


Functions of F-CON iS 1

  • Correction of Fuel Amount and Ignition Timing
    Fuel signal and Ignition Timing are controlled with trim maps inside F-CON iS. Four sub maps for each fuel and ignition control can be easily switched with dip switches.
  • FCD Function
    Fuel Cut at high boost level can be cancelled with FCD function.
  • SLD Function
    Vehicle speed signal can be controlled to cancel speed limiter by stock ECU. * Not for Automatic Transmission and electro-magnet pick up type sensor.
  • Engine Check Function
    Even with F-CON iS, engine check function of stock ECU works. (Except some vehicles)

Functions of F-CON iS 1

  • A/T Shift Up, Shift Down Ignition Compensation
    A/T Shift Up, Shift Down Ignition Compensation To prevent knocking of vehicles with automatic transmission during shift up at high load or shift down for acceleration, engine rpm difference and throttle position is kept and ignition timing is retarded for a certain period.
  • NVCS Control Function *
    Solenoid of Nissan NVCS (Nissan Valve Control System) can be controlled with F-CON iS with RPM + Water Temperature condition.
  • Air Flow (Intake Air Volume sensor) Conversion Function
    Air flow meter signal input can be converted with a 16x24 map with Air Flow Input value and RPM axis. When characteristics of air flow meter output are changed from stock condition, air flow meter signal can be corrected. (Get advice from PowerWriter shops.)
