Time to join the dark side... with up to 32x32 maps, all of that goes away. That many cells (1024) is not always necessary due to perfect interpolation between the points, and VE tuning. The "transition" that many UTEC users complain about does not exist with the Haltech, because it controls the injectors 100% of the time.

 

exactly... resolution is KEY when it comes to tuning, but control over the injectors continually is also very relevant... handing off control to the EMS, or better said, taking control from the ECU causes blurps... this is why standalones such as the Haltech and FCON are superior to piggybacks such as the UTEC...

 

What is the resolution of the utec compared to the FCon iS? I know the FCon iS is 24 x 24.

 

It's a 12x12. They were post to come out with a upgrade wayback. Never heard the lastest on it. Really haven't looked lately. Kind of gave up.

 

I've also had the small hiccup or a transition of Utec kicking in. More when crusing and start to get into it some. I never felt it was a big issue with stock boost.

 

If turboxs would get their act together they could make some good profit.

 

wow 12 x 12. That does seem a bit low. So as far as i can tell the HKS FCon iS unit is superior to the Utec. I suppose people just don't like the fact that it's locked. For the price i would rather go with the HKS unit though.

 

Hi i have ST turbonetic right now on my car. By the end of May i will have my short block done on my 350z stage-1. My goal is to be in the range of 460whp - 480whp @ around 15psi with turbonetic with stage-1 short block. Will UTEC be a good way to go for my power goal and 15psi on Single Turbo, and for day to day driving. I know that HKS F-con will be a better choice but i don't have an extra $2000 to spent. Will it be a big difference in driving between UTEC and HKS F-con at my power goal.

Alberto - Do u think i will have same throttle problems @ 460 - 480whp with UTEC on my ST as you have on your TT car with 600whp.

Thanx to all and Happy New Year.

 

wow 15 psi seems like a high psi for 460-480whp. I'd think it'd be more like 12-13 psi on a ST. Then again, 460-480whp would probably be making like 470-520 tq right?


anyway, I'm glad I spent the extra money on the fcon V-pro and no longer getting one ems, then trying out another, then another, etc. The Fcon has everything you'd really ever need except VTC control, but if you don't have a crazy cam profile that's probably not a huge deal. It's just nice to have that aspect of the car DONE with

 

Yes, power isnt a huge issue, its boost vs resolution available. You will have hiccups in the tune, and it will change from summer to winter in NY considerably. Take it from me do it right the first time. For what its worth I'll take a Haltech over an FCON anyday

 

If you can't afford a V-Pro, why don't you try the F-Con iS. Its about the same price bracket as the UTEC, and has higher resolution. From what i gather it's a better unit, just not user tuneable.

 

Id do the haltech. It will come out cheaper then the fcon and will be just as good.

 

The Haltech seems pretty good

it wasn't available 8-10 months ago when I went with the Fcon Vpro, otherwise I might have considered it

however the Haltech is still new. Even the UTEC was hailed as the most awesome thing ever for awhile until people started realizing it's shortcomings after they ran it for a while. Or the Emanage Ultimate was supposed to be amazing when it first came out...only to find out they can kinda suck.

Not saying the Haltech will have any shortcomings or glitches etc since it's still pretty early to know yet.
The Fcons are pretty solid and well established with the only real problems being they cost more, they're locked, and they can't directly control the cams. It was a pretty predictable purchase knowing those were really the only bad things to expect with pretty much no chance of glitches or flaws showing up later down the road

 

+1. It seems when ever a new product comes out, everyone jumps on the bandwagon suking cack and saying how great the product is. A few month later to a year, the short comings are known. I am not referring to any new product currently out, but that is usually what happens on this forum.

The FCON has been out for many years and it's proven. The biggest con is that is is locked, but that really is a non-issue, as once it's tuned you don't need to touch it, PERIOD! I drove on the same tune for over 1.5 years, without needing a single tweak (once it was properly tuned). So many people on this fourm talk chit about how they like to tweak their cars, but seriously, 97% of them wouldn't know what to tweak on a tuning map. Tuning a map is not like changing an air filter or spark plugs. To further expand on my point, look at the DIY projects (engine builds, ST or TT installs) that end up going bad. Now imagine these same people tuning their own cars or even messing around with the map after a professional tune.

 

So what is the difference between HKS - F-Con Vpro and F-Con is.

With V-PRO i will need on top of the unit ($1,350) Harness: $500, MAP Sensor: $250.00. Right???

Will i need a Map sensor and harness with F-con iS??? How much is the unit???
Also what else i will need with Haltech??? Just the unit or also Map sensor and harness

What you mean by NOT USER TUNEABLE??? - No custom tune, just the tune from Maps that comes with unitt

 

I don't think any of the Fcons come with maps

only authorized HKS dealers can tune the fcons. You and other tuners can't tune it, it's locked so you don't have the software to interface with it.

the IS is a piggyback
the V-pro is a full standalone

 

in addition, if you have one authorized dealer tune the FCON and decide to go with another tuner that also is an authorized dealer/tuner for HKS...they will need the original tuner's password to gain access to the FCON for tuning.

 

So since iS is piggyback i won't need harness and map sensor like you do on V-pro. Will F-con iS work fine with my power goal.

One think is UTEC standalone unit or piggyback.

Thanx for answering my questions. Its a black magic to me. I do try best

 

UTEC is a piggyback

I don't know tons about the Fcon iS. I think it'd probably be fine for 460-480whp and 15psi though

I don't know what harnesses etc you'll need for the iS

 

it is piggy back when not on load but on load/boost, this thing take full control of your Timing and Fuel. So it is a hybrid Piggyback and Standalone on load.
