New Product

F-Con SZ is a new model based on upgrades of the F-Con S, but with new powerful features.

Although the conventional F-Con S processed the injector drive signal and the ignition drive signal from the stock factory ECU and changes the signals at arbitrary fuel consumption, and ignition timing to suit the engine specification, the F-Con SZ included a feature to further refine the fuel compensation. This feature is the air flow conversion function, which is like an Air/Fuel feedback function, etc.

Moreover, with the use of F-Con Navigator, which is sold separately at the same time, it is possible to change the arrangement data of the F-Con SZ much easier on fuel injectors & ignition timing.

A compensation map is created in the F-Con and is used to control the fuel signal and ignition timing.

Fuel Cut Defencer (FCD) function
The fuel cut by factory ECU is due to the ECU receiving a signal on excess intake air, but the F-Con SZ cancels such signals by re-processing the air flow signal.

Acceleration Correction function, AIC function
The F-Con SZ has an acceleration correction function that enhances acceleration response across the RPM range. This function also supports an additional injector function (AIC) that drives & controls up to two additional injectors.

Option voltage output function
For engine loads. Two optional output terminals which can read a voltage output signal freely at a number of revolutions.

Error display function
When a sensor failure is detected, the failure is displayed via an error LED light on a front display panel.

F-CON SZ-ADDITIONAL FUNCTION

Air Flow Change function
A gap in the air flow output which is detected from the output of an air sensor, is rectified in the F-Con SZ by using an air flow change map and air intake system piping.

EIDS function
Engine stall is prevented by changing the air flow sensor signal output of a turbine when further boost is prevented.

A/T shift compensation
This function avoids the ignition from retard angle compensation when an up shift is performed in a car with an automatic transmission.

This prevent engine knocking which is very common at the time of a transmission kick down.

A/F knock level monitoring facility
Data monitoring & data logging were achieved in A/F monitor, O2 monitor, the knock level of the A/F-Knock Amp, and from the various internal compensation values. These are useful information when creating an arrangement map.

A/F feedback function
A/F feedback control is possible by carrying out a shortened setting time. This is achieved by carrying out an A/F mask map, and an A/F map.

NVCS control function
For Nissan vehicles, the engine loading is controlled by Nissan Vehicle Control Solenoid, or in short, NVCS. It is possible to control the ID parameters directly.

Proper and wiring processing are required for simultaneous use with an AIC function.

Immobilizer ability
The F-Con SZ has an immobilizer function. When ignition is turned ON, the fuel GCC input terminal voltage is checked, and is the voltage reading is different from the voltage setting, engine starting is prevented.


* With F-CON Navigator, F-CON SZ setting data can be monitor or edit.

--

NAVIGATOR

This device is possible to act as a monitor for various sensor functions in the vehicle by connecting it with the F-CON SZ.

MONITORING FUNCTION

Engine RPM: Displays the engine RMP power supply voltage. Display Battery voltage.

Air Flow output value: Display the below information according to the following,

Hot wiring Type = Voltage

Carlman = Frequency

Intake Air Pressure = Voltage of pressure sensor

Ratio of air to fuel: Display the ratio or percentage of air & fuel.

Injector opening ratio: Display the opening ratio of injector.

Circulating Water Temperature: Displays the water temperature of the circulating coolant water.

Fuel Revision Value: Displays the Fuel Revision/Compensation Value which is adjusted by the F-Con SZ.

Ignition Revision Value: Displays Ignition Revision/Compensation which is adjusted by the F-Con SZ.

Intake Air Pressure: Displays boost pressures.

Speed: Displays driving speed (* This function is not applicable to some vehicle models).

EDITING FUNCTION

Fuel Revision Value: Edits the Fuel Revision/Compensation Value by using the F-Con SZ's revision map.

Ignition Revision Value: Edits the Ignition Revision/Compensation Value by using the F-Con SZ's revision map.

EIDS: Switching on/off the EIDS function.

FCD: Switching on/off the EIDS function.

*F-CON Navigator can also use with F-CON V Pro .

F-CON SZ Price: £855
F-CON Navigator Price: £310

Gaz,

Just got both of these fitted.

Any idea where I can get an English user manual for the Navigator?

My Japanese is a little rusty. :innocent:

Seems a nice bit of kit but needs the dealer to set up the F-Con SZ which is a PITA.

Cheers

Hi Loks,

I thought the unit only displayed in english!

If so theres bound to be an option that changes from Jap > English.

You could phone HKS Europe (+44 01480 861 997) but they are probably as much use as a chocolate fireguard, worth a try though?

Regards,

Gaz.

Just as a sidenote, will be really interesting to see what your thoughts are of this unit once setup etc.

Please let us know :)

Gaz,

Has been set-up now but haven't driven in any sort of anger yet. Initial drives feel like it picks up earlier in the rev range. Being an auto, it used to bog down a little bit from a standing start.

I will let you know more after a few :devil: runs.

Re: the Navigator, yes the display is in English but the manual is in Japanese. Some of the readings I'm quite confused about and therefore needs some sort of explaination beforehand.

I'm also a thicko :blink:

Gaz,

Are the Navigator's only applicable to the F-Con SZ?? or does it work on the other F-Con range of HKS ecu's??

Nice to see that HKS are now following the route of Apexi etc with real time readout info!:D

Stu,

It says on the box that it is suitable for use with the F-CON SZ, F-CON S and F-CON V Pro (ver. 3.1 or newer).

HTH

Any ideas what all the display readings should be showing? :blink:

Thanks very much for the info Dave........

Looks like my mind is made up and i will be ordering one very soon.......;)
Any info i collect when i get the unit! i will gladly pass on....

BTW I was the same when i first got my Apexi RSM with FULL Japanese instructions, so know how you feel mate!:D
