My next winter projekt will be going F/I. Some of you might have read some post/topics with questions about this, but on this question i cannot find much info here and on the .org
I want to do my homework as much as possible in advance, so therefore my question: What to take...Haltech Platinum Pro 350Z or HKS F-Con Is.......??

I'm not really that tech so do not know if all the things possible with Haltech are even necassary. I know it has knock possibilties wich F-Con doesn't.
Also there is quit some price difference......USD 1999,- for the Haltech and USD 795,- for the HKS.

Being an estatic guy i liked the posibilty of the HKS Camp 2 system being possible to connect to the F-con and can be shown on my LCD screens.
Do want to monitor things like....Oil temp.....Air/Fuel ratio.....Boost, but do not want to many cauges all around in the car.

Any ideas / suggestions......??
 
my advice. if your not the type of guy who is going to really learn everything about tuning the thing & eventually think about tweaking it yourself, then don't decide what it is that you think you want or that someone else just tells you to get.

you will need a local tuner to work with. find the best you can & then speak to him. let him do what he has the most knowledge & the best support with & what he sees as the best for your application. follow his advice & you should get as good as he can provide. assuming you choose a respected good tuner you will get a respectable good tuned & running FI setup...


who you choose is way more important than what you choose if your not looking to really get into the tech of it anyway, just my 2 cents :tongue: also buying from your tuner will get you much better service than walking in with your own stuff most times too, yes he will also make money on the parts, but that's what he's there for & what his business is, the money you give him will be reflected in the service & care he'll give you, in the end if you spend 20% more by going through the tuner than you could have by scrounging the best price on the net, you will also have at least 20% better service & caring from the tuner toward your car, & most times it'd be way more than just 20% more... you could wind up with 150% or more better service & caring about your vehicle for that extra 20% you spent with him... the only time it pays to be cheap is if you also plan to be more self reliant in the support department with your own tune...


now if your looking to get into the tech end of it & you are looking to be more self reliant in the tuning department, then we can discuss the benefits & trade offs of each system here I guess, I'd be very interested to know all about what's out there & the deal with each, but I plan on eventually doing my own tweaking & tunning too, so I need to know this to choose, your tuner will already know & you telling him how to do what you want is usually not as good as him telling you what he would do...


of course it's never a bad thing to also educate yourself with what's out there & learn more about the tuning process & be more knowledgeable when you do talk to a tuner...

also, realizing where you are, all the more this can be important, maybe in your case it may make more sense to buy your own equipt because of availability there, but you def wanna get what your local guy can work with at least too I guess... won't be much good to have a really awesome piece of equiptment that you can't get anyone to work with...

Thanks John for the intell....!!

There is a guy who is a retiered Nismo/Nissan tech guy. Haven't spoken with him yet but want to do a bit off research in advance (like you suggest) first too.
I've heard he is formiliar with the Haltech system.
I need to hear him out some more if this is realy duable for him as i honestly do not know any other "Nissan" tuners around here.
Do have a good contact with a VW / Audi tuner who i also want to call.
Thing is some guys are really honest and tell you realy what they think is best.....others just talk the way it increases their wallet. Don't know wich way he talks yet........:confused:
 
that's 90% of the battle is knowing if he's talking from the heart or the wallet & why I say that who you choose is more important than what you choose. in the end your in there hands. unfortanatley it is hard to really know the difference which is where research comes into play. talking to guys that have had there car built by them is always a good starting point...

it always sounds good before, especially when they know what there talking about & you don't, but it's nice to hear how it felt from someone in the after stage, the guys with the best reputations have built them by just this, opinions by those in the after stage...

if most are very happy & have complete confidence in the tuner after there car has been built by them that's a good indication that you may be too. again, I guess it may be tougher where you are but the same basic rules still apply really ...
 
Thanks Gilley for the link, will look into that forum as well.....lot's of intell there i know.

John that's still the big issue around here. There aren't that many people building N/A to F/I that i know. Maybe a hand full but will track those down :laugh:
Most what we see here are OEM F/I cars like skylines......EVO's and Subarus are such engines being build in other cars.
The guys i bought the engine from used a stand alone from AEM but the guy who would tune that didn't do a good job so no Stand Alone for me here in the Netherlands.
Do you think that guy i know who does VW and Audi and is engineer who writes his own programs can do my car also with piggy bag.......i mean is the writing of euro cars and US/Japanese cars any different from eachother....??

Thanks for your help buddy :tup:
 
I've come to the same conclusions that John talks about. Been doing my engine management research for almost a year now. Since the shop is SO important, I asked for suggestions of which way to go and the preferred module for one shop is different than another - for exactly the reasons already discussed.

I went to a local tuner meet just to get some names of shops and tuners close to me. What I found is like what you are saying - very few FXs have FI, and very few shops have experience installing them. So the best you can do is find a tuner familiar with the VQ engine.

So far the guy/shop I found is 4.5 hours away. They have done ONE FX turbo. But I'm thinking the drive is worth it. If he's keeping the car for a month to do the install and tuning, the distance doesn't mean enough. By the way - this particular shop recommends the ProEFI. It has a pretty decent aftermarket interface - meaning you can hook up a laptop and tune yourself. But of course you don't have to. Good option for those of us who want to learn how to tune our own FXs.

Finding a tuner is the key. The module they are familiar with and recommend is the way I would go too. And that's how I'm making this "selection" also.
 
ray, man, it's hard for me to know if your friend can do it or not, all he really needs is experience & a dyno also goes a long way towards getting a good safe tune, really tough & time consuming to do without at least a dyno, has he ever even done any actual dyno tuning with adjusting fuel & ignition maps? have you asked him if he thought he could?


the problem with FI is your playing with fire, & if you make a mistake in the tuning area your going to get burned. a good tuner will start out safe & mold the map to bring in performance without hurting anything or allowing anything to get hurt. he'll get you to the point of making safe reliable power, & then it's up to you to always monitor a few gages to make sure nothing has gone wrong to tell you to back off or your going to damage something, but a good install & a good tune should be good for a really long time.


just talk to tuners, tell them what you want to do & see what they recommend & how they would go about it . feel them out & then use your judgement, in the end who you choose is going to determine what you wind up with...
 
I've visited a good collegue of mine this morning who worked on the engine i bought. Not built it but put it in and out etc....
He knows a some as well and also being an HKS dealer i asked him this question. He called HKS europe-importer who sells both products. There first advise was to go for the Haltech with just having more options to adjust and tune then the HKS does.

There is a good dealer in belgium who has a lot of exprience with this product and Dyno tunes.
Going to england ( were this importer is at ) is also a posibility. They do a lot of dyno work and big big projekts. It is a couple of hours journey for both ways but i think it 'll be worth it.

Talking with my collegue here further this morning he said the TUNE wich turbonetics did on the ECU wich they delivered along with the kit worked also great.
Turbonetics don't know the Infiniti so they say they can't do it, but the guys here might think it's the same ECU as the 350Z.
Told him that custom ECU'ing true turbonetics is done by Technosquare. So he said why don't you Tune your ECU then by Technosquare wich is even cheaper in stead of buying such and expensive piggy bag and renting the Dyno for half a day.....hours labor for the guy who's going to tune it...............

What you think John........
 
Another note guys..........Is the Haltech mounted via the OBD port......or at the ECU....??

I want to mount the HKS Camp2 kit as well for messuring boost....temps...etc.....but this need to be connected to the ODB port. So if the Haltech is already there i cannot mount the Camp2...........Jumbo....you now have the Haltech.....do you know...??
 
it goes inbetween the ecu & the engine harness, unplug the harness, plug it into the haltech & then the haltech plugs into the stock ecu... the obdII plug will stay unoccupied, BUT I don't know for sure weather the obdII readings are going to be actual or are going to be what the ecu is being tricked into believing, I'd assume that the obdII data will just be what the haltech is feeding to the oe ecu & may not be actual... not to sure yet...

Ok clear. Don't matter that much as certain intell is isn't touched by the haltech i gues.
Further i will add some additional sensors to the Camp2 so it has a direct intell of the engine for the most important thing like pressure en temp.
