I'm looking to get a new EMS very soon now - along with new camshafts to increase my turbocharged vehicle's performance. That said . .

I've heard good things regarding the new HKS F-Con iS piggyback system, but how is it compared to the UTEC? Anyone have experiences with both?

Now the third option would be to just go all out with the F-Con VPro which I'm tempted to do, however that's a very expensive step and I don't know if I can justify spending 1-2 thousand more for a standalone system IF the piggybacks and be JUST AS EFFECTIVE.

Thanks everyone

 

fcon is a luxury.. if you're on a stock block, you can get by with a utec. it's more like 3k with tune, not 1-2k..

 

Heeeeeeeeeere we goooooo...lol..Again....

 

Why not look into the hydra if you want a full standalong, and you can tune it yourself.

 

I know that. However I would like to hear people's comparison's of the F-Con iS (that is not the Vpro) vs. UTEC.

And yes, I've searched forever.

 

Your best bet would be to call your closest shop who is HKS certified and talk to them about the pros/cons to your question.. I dont think there are many people here whom have the knowledge regarding the IS. It is a pretty new system and not much is known about it (by us 'end users').. Your tuning shop will likely be able to give you much more info than anyone here.. Hope this helps

 

Just get the F CON V Pro.. Dont waste time on anything else....

 

I posted a similar question on the FI forum and never got any real info. Ended up calling a FCON Pro dealer/tuner and they said it has some bugs HKS and the tuner hasn't figured out yet. It will scale larger injectors but not sure how well. You can get one for no more than $1500 including the harness. I don't think there's anyone yet, who's used it with FI. I'm in the same boat between the UTEC, FCON V-Pro and FCON iS.

 

WE ARE TALKIGN ABOUT THE "IS" UNIT not the Vpro... ID too like to see a comparison...
Does somebody need to be HKS certified to sell tune the IS units liekt he Vpro?
HAs the IS unit had success on other cars besides the Z?

I imagine it probably has a nicer interface that is windows based


And those bandwagon hoppers need to stop their stuff... with a good tune the Vpro is not needed unless you are looking at HIGH whp numbers ona build engine.

 

i hear you
it will be a "Heeeeeeeeeere we goooooo again" if poeple dont read that the comparison is between the HKS IS and the UTEC, not teh vpro vs the utec.
Some have already started with "vpro only way to go" thing

 

Anything HKS = overpriced. Stick with US products!

 

The UTEC is proven on many 500+ whp Z's... Plus it controls boost so you don't need to buy an additional boost controller. UTEC FTW.

 

i dont think thats the point of this... and its debatabe that all hks is overpriced. Price wise the IS and the UTEC are "right there" but what else...?

 

I remember all the loops the last thread like this had. Should be interesting!

 

ahh.. missed that.. dunno much about is, butt it's a piggy back, right? i'd say utec, between the 2.

 

Yes it is a piggyback.

I can afford the VPro, but I can't JUSTIFY spending the cash on it right now, since I have a stock motor.

 

you won't get many response as no consumers or end users have the ability to tune the IS. It is a dealer-only tuning. I suppose that is good for HKS dealers, but not of any interest to tweakers!

 

Yes and that's what I was talking about. The FCON iS is considered a PRO SYSTEM and requires a Pro Dealer to sell and distribute it, this taken directly from their website....


Online Catalog > Engine Management >
PRO Systems

"HKS PRO System are high-level engine management systems that are only available through HKS Certified Pro Dealers. HKS Certified Pro Dealers are a select group who have met HKS' strict criteria to tune vehicles with HKS' Power Writer Software. All HKS Pro Dealers have been trained by HKS, and have a Dynomometer in house."

 

that sucks that hks is that **** even on their lower end EMS like the FCON is
and i my post wasn't directed to you btw, it was more towars jonb7007s "amazing" comment of "Just get the F CON V Pro.. Dont waste time on anything else...."

 

I iS is a very advanced piggyback system compared to other piggy backs in that it is able to communicate with the OBD2 system and automatically clear out check engine lights and also keep the ECU in open loop mode at all times or additionally at time when it needs to control things. It still modifies the crank and cam position sensors and uses the OEM MAF scaling type system to control the injectors. It can be used to eliminate the stock MAF and use the HKS pressure sensor instead but most maintain the stock MAF.

The UTEC is much better in the fact that in boost in directly controls the firing of the injectors and the coils (standalone style) as opposed ot the iS which is still unsing the OEM inputs and modifying the signal to "fool" the stock ECU. If you are FI and have a VQ35 the UTEC is a much better choice.

The iS is designed for HKS to use with its Bolt-On Upgrade kits becasue the price point is lower then the Pro. It is also a great unit for those that have Supra's, 3000GT's and 300ZX's that want to convert from MAF to MAP based tuning (those car's gain 30 to 50 hp just by converting) since they are FI already and not nearly as much change is required to get theor ECUs to work with upgrades.

Hope that helps. In the end the UTEC is what you want to go with for you budget (obviously someone is going to say the Pro is the best and I agree but for your situation and exact question the UTEC is the best)
