Haltech V Apexi Power Fc

[pnblight]

I wouldnt tune a car in the top end with Closed loop anyway

The haltech is the way to go mate

i installed one in a customers car around 3 weeks ago

his getting 380 kms out of a tank and the car is making around 400 rwhp

The tuning points are more finer and it is a benefit later when changeing ignition systems ETC

Even with large injectors the haltech can tune very fine.This skyline i just installed the ecu in has 850 or so cc sard injectors

The haltech is plug n Play

gets rid of the AFM

its $2750 Supplied installed and dyno tuned.

well you have proved my point for me

my gtr runs 530rwhp at 500kms plus per tank

and xspeed have gtr running higher hp running same range

AND the close loop is automatic and is for fixed throddle position (cruising) you cant and would never use the closed loop for tuning top end

I certainly wouldn't tune a car in closed loop in the top end either unless you want to destroy it!!! Cost of PFC and tunability is what makes it the number 1 choice of ECU for skylines. Also manufactures used closed loop as CATALYTIC converters operate most efficiently at this stoiciometric point.

I paid:

PowerFC + H/C $1100

Tune - $450

Z32 AFM - $350

=$1900

I made over 400rwhp

I also recieved more than 380km's to a tank

I also had 740cc injecors with an idle as good as factory

So my car did exactly the same as yours, for $800

Thats virtually a set of cams or Almost a new diff

or

Almost a new clutch or Alomst a set of excellent pads/rotors

... 130 corona's in a club or 220 odd pots at the pub

See where im heading here?

At a cost of more than $800 more. Haltech is quite a badly priced opition.

Is there a hidden benefit i can get from the extra $800 that you didnt list?

Seeing we are all having a bite of the cherry YEAH THERE IS ONE THING

4 Lady's at one time for 1 Hour...Go Power fc....FIGHT FIGHT FIGHT

[FATGTS-R]

I have no doubt the haltech will make great power and the car will drive fine BUT it will not compete when it comes to balanced performance and fuel comsumption

Why do you say that?

You say it wont compete when it comes to balanced performance, what is balanced performance?

You also say it wont compete with fuel consumption. If the Haltech is setup to use closed loop in the same fashion as the FC why would it not compete?

[fEkuaR]

thanks to all who answered my question in regards to closed loop function.

[Sydneykid]

I certainly wouldn't tune a car in closed loop in the top end either unless you want to destroy it!!!

I tuned the Motec in the R32GTR using the Self Tune function (being Motec, enabling that function costs more of course). Simply set the A/F ratio aim target and did a few laps. That’s about as “closed loop” tuning as you can get. The Nissan LeMans cars ran closed loop for 24 hours for better fuel economy (less pit stops).

Closed loop power tuning is the future, no more dynos (yahoo).

cheers

When that fast hatch bloke eventually gets his powerfc software out thats supposed to handle closed loop tuning.

[dead32]

powerfc = nissan basemaps = built for nissan only aftermarket rcu *that im aware of* that uses nissan base maps e.g idle

[MR331307]

Yeah $800 Cheaper and when it comes time for ignition upgrades

......

The HALTECH COMES WITH A BASE MAP and is PLUG and PLAY

I personal dont like the APEXI computers.The Haltech is more advanced.

If you want a Good ECU with closed loop that works Acurate Chose either HYDRA,MOTEC,Autronic

MR331307,

I'm pushing 10.6-11L/100km's out of my RB30DET, no open road driving, all short local max 20-30km trips.

Providing the cars warm it does get stick.

It drives like factory, cold and warm starts perfectly and has a perfectly stable idle. There's literally nothing I can pick with it. Driveability is perfect. It hangs in closed loop until it see's boost.

Apart from picking up a little more economy with more flexible closed loop control is it really worth the extra $$.

From my point of view, No. I don't need fandangled features that loose their novelty soon after.

You can't argue for sub 1k price tag of the apexi pfc + h/c, sequential injection, 6 coil drivers, closed loop, stepper motor control, boost kit option, excellent control of large injectors + more it really is a bargain.

There will always be better out there but it comes down to if its really warranted.

Yes my coils are on their way, they've done a minimum of 217,000km's and I'm up for ~$550 for a set of splitfires.

I think thats a load of crap.

Thats seriously good consumption considering I'm around the 14-15L / 100Km for my RB25DET...

... but then I dont drive like a granny ;-)

I meant narrowband 02 sensor as in 14.4:1 at full load. Off topic but have you done any testing regarding piston crown expansion rates at various AFR?

Giving it a boot full through the hills and back for almost a whole tank appears to not make too much of a difference in fuel economy. drops down to flat 400km's per tank, once i've seen 380km's but that was absolutely flogging it every chance I had. So yer worse I've had is ~13.5L/100km's roughly.

I must admit, not many R33's for what ever reason return good economy. I know of plenty R32's pushing close to the figures I do.

[fEkuaR]

I average around 9.8-10l per 100km in my 33 gts-t thats still standard ecu.

Ok... i'll bite... what ignition upgrades do we need now?

Stock RB25 coils are good for excellent power, if they die, replace them with splitfires... which again are good for excellent power.

If 350rwkw can be had (i actually made more), what more do you need in a street application?

I mean come on, your bordering on fantasy land half the time.

1) Who on earth really needs more than ~350rwkw for 99% of applications?

2) How is Haltech more advanced?

3) What extra features do i need that are going to aid my daily life?

4) Will it get me more power? More response? More economy? If so, why?

Now, dont base it on hearsay when examples of over 400km/s to a tank & PowerFC are all over the place

You said it yourself, you dont like them, and thats the only reason you are against them because there is nothing majorly factual to justify $800+ price difference.

If the Haltech was the same price as a PowerFC installed/tuned, different story in the bang for buck world.

So now we have established that you just dont like them, can you stop trying to pass off ECU's that are almost the cost of TWO PowerFC's with a minute amount of differences.

[DoughBoy]

In all fairness how many people run an electronic boost controller with a PowerFC? Most other brands have this feature on the ECU, so there's a saving already.

Also enabling different features like shift light, nitrous control, 2 step rev limiter, aftermarket dash compatibility, logging, etc etc. If you buy a PowerFC, EBC and some sort of 2 step rev limiter you're already over the price of a Haltec, and the Haltec isn't limited to that specific model car.

Not trying to play devil's advocate here but have been weighing up a whole bunch of different ECU's for a new car project, and once you look at the electronic management system as a whole it's expensive no matter which road you take, and the more options the better - even if you think you'll never use them down the track you can always start experimenting..

[ish]

yeah i have to say i am with DoughBoy. I wanted more features with out the extra moduals all through out my car. The PFC only offered install benifits and more as in dollars for independent component outlay for what i wanted.

Agreed, however it comes down to the intended use.

Its a street car, do you really need those feautres that are only going to attract attention should one be pulled over. Not sure what its like in other states but here in SA if the car even looks to be slightly modified your off for a full inspection.

If I were to often hit the track I would most definitely have choosen a nicer ecu for the car. I just don't have the need for the added features. Hell I've got a PFC handcontroller but it sits in the draw next to the bed.

Honestly, I just drive the car and give it a little stick from time to time. Nothing serious, which explains why it still runs std height suspension.

I have plans for the car in a year so (I have no intention selling, they aren't worth anything) I may see the arse end of the pfc as I'll be dropping something in that has better/quicker datalogging with more features.

So its my opinion for a streeter, you don't need these other features unless your in to rice/hardcore street racer vtec yo and want that shift light reflecting off your face or a launch control system to show how sik your car must be.

On the track or regular at the drags.. its a different story.

[Spook's_Skyline]

my gtr runs 530rwhp at 500kms plus per tank

yor car is a freak to return figures like that
