Looking to purchase a HKS FCON V Pro but what I would like to know is there any requirement that I need V3.24 over V3.2.

I have found a V3.2 and have a local pro dealer that can tune for me

 

Very 3.24 has some additional features that might interest you. It allows for knock retard, a greater range of feedback under closed and open loop compensation, and more tuner parameters to facilitate tuning. But if you found a good deal on version V3.2, I think that would be fine....its still light years ahead of AEM and most other engine management systems.

 

The FCON Vpro! Ahh what can I say. Its like having sex with out a condom! Its just soooo smoooth. the best thing i ever did to my car (beside going FI).

 

There is no difference between the v3.2 and v3.24 as far as hardware, the difference is only in the software so if your tuner has the current software version ,you are good to go

 

Hey Sam, the new installation PDF files say that the older VPRO versions do not offer the V3.24 functionality. As all the FCON dealers know, there isnt one massive and comprehesive instruction manual, so we sometimes have to read between the lines.

 

hmm. I would of though Knock retard would of been included in the 3.2 unless your saying it does it a different way.

I will have to chat to the local Pro dealer and find out what costs are involved in upgrading the unit. Anyone got a ball park figure?

My car will not be HP monster looking to have around a maximum of 400HP (probably less) at the wheels as a dialy driver/weekend racer.

 

I think they are refering to the to the v3.1 version not the v3.2 .and there is one massive and comprehencive instruction manual .you 'll just have to read japanese

ご覧いただき有難うございます。 御協力の皆様に感謝しております

 

Oh, I dug out the file. Version 3.24E is the latest version, 3.23 is the version before that..and version 3.1....not really sure.

Version 3.24 can communicate with older VPRO's, but the new functions will not work (taken from the HKS manual)
New features of the V3.24

1) Ignition Knock control: Timing may be retarded based on a knock level vs. RPM map.
2) Atmospheric Pressure: When map sensor is added, fuel can be corrected by load vs. barometric pressure trim map
3) Water Temp and air temp short/open values (not important)
4) Fuel Tank capacity and fuel consumption tracking
5) Power Holding time: Can adjust the amount of time the VPRO is on after key is off.
6) Fuel Trim sub map trim range improved
8) Feedback correction adjustable range is improved.

That said, Sam says he has tuned the older versions, and the new features work..sooooooo...maybe this was lost in translation.

Either way, if you can get a good deal on ANY Vpro, just grab it.

 

Another question for the HKS experts.
Is the Valcon + Vcam Pro Kit for the VQ that was shown @ SEMA & just released in Japan a stand alone electonic adjuster & camshaft kit, or must it be used in conjunction with the F Con Pro?

 

More info on the unit. The seller says he bought it about 7 months ago and says there is a RED DOT near the serial. Apparantly this means something.

I'm just waiting on the serial to confirm with my HKS dealer

 

No it can be used as a standalone unit ,hks maybe considering separating the cams from valcon controller so the price can be more reasonable for the end user.it should be released in the end of Jan of 07. with having the ability to do cam phasing in the near future ,the fcon v pro will be untouchable .

 

Sam thats great news, especially for NA motors.
The main reason why any of the available aftermarket camshafts don't put out any decent increase in power at higher revs is because the OE ECU fully retards the inlet cam at just over 6K and no amount of ignition & fuel timing that the likes of Utec, F Con, Unichip are able to do, can overcome this.
Any idea of what the expected retail will be?

 

For a given camshaft profile a later valve closing event is desired to take advantage of the intake charge's inertia at high revs. I see no problem with the full retard at high revs. Every OE cam phasing-type VVT that i know of operates in this manner. Unless i'm misunderstanding what you're saying...

 

ROFLMFAO. That's a good one.

 

LOLOLOLOLOL but yes true AAAhhhhhhhhhhh....

 

This is correct. But to Nathan's point, control over camshaft phasing will allow the tuner to retard further, or advance slightly, in order to maximize power in the midrange, and up top. With the massive change in VE by adding FI, its unlikely that cam phasing is optimized for these conditions.

 

got the unit and tested and seems to be all okay. Just waiting on the harness.

Does the FCON support launch control? I thought it didn't but some users on other forums post they have HKS Launch Control. Anyone got any ideas.

 

If you are refering to two-step launch, then yes it does support it. However, I was unable to get it working in the auto mode, where the two step is always engaged when the car is not moving. The sure fire method, is to hook up the HKS control ****, and switch the two-step on in this fashion.

 

Cool.. Learn something new everyday. Sharif do you have any literature that you can pass on of this so I can ask my pro dealer. I have not asked him yet so in the event he has not done it before if I had some info it would be fantastic.

 

Let me clarify what i'm after and if we are on the same page as the response I got below is not what i'm really after. What I'm after is the ability from a stand still you can press and hold the clutch in and fully depress the throttle to floor but stays at 4000 rpm till you let go of the clutch.

Response:
When they say launch control, do they mean the computer runs a different map momentarily? You can activate a "scramble" map using a switch. I guess you can set the rpm cut and have the map tuned to dump fuel into the exhaust so to create boost so you have boost while sitting still. But I didn't think it has something like traction control to help you launch.
