Aftermarket Computer

[markimak]

retuning ur standard computer hehe.. all u have to do is get a flat and its reseted. sucked in. if u want reset ur ECU and run what it gives u. or get the PFC. im gettin a dejetro in the not so distant future. easy to tune no AFM. its all good but runs off stock sensors. but u can always replace them oneday.

KNOCK sensor saves engines!.. buy PFC

[R31Nismoid]

Dont waste your money on a powerfc or getting your standard Computer Retuned.

Why is that?

Wanna post some fact for us mate?

considering around (at a stab) there are 50% of users here using the PFC, as opposed to anything else... something must be pretty good about them wouldnt you think?

[rob82]

Buddy Any computer running a AFM is rubbish.Stick to computers running map sensors,you never have problems with them.

use a haltech E6X or E11

I have plenty experience with them and they are unreal computers

I am currently running a HYDRA computer.Which is like the E11 but is much better for a street car.No more Manual Boost Ts Or having to spend money on a Eboost just all runs off the computer.

All Good Computers Have outputs for NOS,Turbo Timers,ETC and you can change Coilpacks ETC

So if you are going to buy a computer Spend the money on either

Haltech or HYDRA

If you dont want to spend as much Buy a Mircotech

Dont waste your money on a powerfc or getting your standard Computer Retuned.

Spoken by someone who has no idea what a real ecu is. If you want to go map based then there is no other option but Autronic however like Sydneykid said no other aftermaket computer apart from link has knock sensor input and output even if it is only to the dash. The problem with running AFM's is that they degrade with time so they need to be replaced, but they still are the best way of metering incoming air bar none. I could talk till I'm blue (as could other members) in the face as to why the PFC is the better option but it still doesn't seem to sink in.

Oh well.

[MR331307]

Nah buddy

The reason why everyone runs them is because they are cheap

Far enough they come with a base tune but this is only good pretty much for a standard Skyline

They are good for people learning to tune ETC

If people actually Look at Performance EFI cars in Australia Serious cars arent runing AFM all are running Map Sensors

The tuning Capabilites of A map Sensor car are alot better.If you pop off a intercooler pipe You can still run the car,Accuratly control Boost through the Computer.

ETC

I dont have to explain to you

If you think you are so good with Cars and computers you should Realise Which Type of Load Sensing is better

99% of the new Computers on the market are straight Plug ins for a Skyline GTS OR GTR

I wouldnt go past these computers

And prices of the computers are just as cheap

Mircotech $1200

Haltech $1800

HYDRA $1800

As for Knock sensors

The hydra runs them and retards timing or adds fuel depending on the way you tune it to react to the knock

If you want a knock sensor

Run a Seperate Knock Guage and sensor and watch it like your boost guage

PS a computer with hand controller is a computer For a CHILD

im still waiting for some fact

cheers

[MR331307]

ok

Ill give you some

RING HALTECH AND ASK THEM

They will explain to you why there computer is better then the power FC

[R31Nismoid]

No.

I asked YOU. Your the one saying the PFC is no good.

YOU post your argument as to WHY with some fact

dont go fobbing it off to someone else.

Makes me think you dont have any fact to post up other than bagging the other product

[MR331307]

OK

1)AFM not to great on lasting a long period without Stuffing up like GETTING DIRTY ETC

if they get dirty they dont read Correctly and Stuff the tune

2)The difference Between the PFC AFM computer VS Haltech,HYDRA computers is that With a Map Sensor the load Maps are more Accurate.You can fine Tuning alot more Efficently.

3)The POWERFC wont idle if you have 1500cc injectors as the rate of tuning in the maps cannot go small enough

4)Software updates and Firmware updates are always Upgradable in these ECUS

5)A car with a AFM if you remove a intercooler pipe it wont idle it will stall reason being is that it wont read the Vacum maps Correctly due to the Air intake Being in front of the turbo instead of in the manifold.you remove it on a Map sensor car the car will idle and rev to suit.as you tune the Map to suit Rev To PSI instead of Rev To TPS or afm Voltage ETC.

6)Data Logging on these Computers is a beneft

7)Abilty of changing the type of Ignition you are using ETC

if you are running standard coil packs and they stuff up instead of buying splitfires or secondhand coils you can go to FORD buy EL coil packs of the XR6 motor for $300 and you will have a much better ignition system and will be able to change unlike the PowerFC

One benefit the PowerFC has is that it is Premapped and does have Knock Sensors But so does the HYDRA and they are both Plug in

Would you like me to keep on going Champ

as im getting tired

i do have to go work tomorrow

Ok

1) Irrelevant. I had my AFM for 15 years. Never had a problem

2) I think the PFC (for a street application) gets into the depth that is needed.

3) You arent using 1500cc injectors in a street application are you? It'll run 1000cc injectors no problem, smooth as silk.

I've also seen my own car run 740cc injectors, idle was smooth as silk

I've love to know a street application that would require bigger than 1000cc

4) Does the PFC Software need updating?

5) Could you not move the AFM after the turbo, and before the plenum? Would work no problem.

6) PFC has datalogging

7) Stock coils (RB25) are good for over 300rwkw, failing that there is a booster you can purchase.

The PFC comes with cold start and other nice things that you wont get on any other ECU from opening the box.

I would like you to keep going, as the above 7 reasons, really couldnt justify me spending over $800 more on just the purchase of an ECU.

Bringing 1500cc injectors into the converstion doesnt fit what we are talking about.

A Street Application

Please try remember that in your resopnses.

Look forward to your reply

[carl h]

you could always get a rb25pfc and swap the injector triggers for cyls 5 and 6, should be mint but you will need to upgrade injectors tho to suit.

it works tried it on a buddies rb20/s14 wasnt too happy idling due to his car still running on stock injectors (270 rb20vs370 rb25), but it does work and all you would need to do is to take the values from a rb20pfc and cram them onto the 25.

[N I B]

Its hard to buy a bad ECU these days so use an ECU your tuner is happy with as long as its value for money.

[rev210]

The Power FC does very well for the money, so well you might as well go the whole hog and by an autronic or motec if you need more.

Ant over here in perth runs probably the highest horsepower street GTR in Australia, uses the power FC dejetro.

[Sweetleaf]

11.97 is still over 1 sec slower than its last ecu on a stock stroke engine.

PFC is good value for money but the AP jobs not so good value.

[Jetdat]

the equation is very simple...it goes like this, from my experience...

if on a budget or dont wanna spend big dollars PFC is great..

if on a big budget then Autronic or Motec and take to the best tuner around(if in melb i can point out arguably the best autronic tuner in aus)..

i played with Wolf 3D, Link and Haltech in the past on various cars, never would i wanna touch them again...

[OPASEN]

Ok then how about for an auto rb25det? Ive been askin around an ive had many differant answers... Like "hahahah your screwed!!" and "good luck man"..... my mate rekons you can only get a piggy back system.... Ive got no idea aye.... Im looking to upgrade the turbo too so what do ya's rekon?? whats the G O?

[rev210]

NIB is right on the money. The tuner is the weakest link in the ECU choice pick one your preffered tuner is good with and you will most often be happy with the result.

Buddy Any computer running a AFM is rubbish.Stick to computers running map sensors,you never have problems with them.

MR331307, running AFM on most set ups is not rubbish. For a street application in most cases it is better.

Dont waste your money on a powerfc or getting your standard Computer Retuned.

I’m guessing for most people their GTR’s are their primary transport. There is significant time the car is going to be off the road to set a system like the Motec or Autronic units properly so in most cases a plug and play unit with a base is perfect.

considering around (at a stab) there are 50% of users here using the PFC, as opposed to anything else... something must be pretty good about them wouldn’t you think?

Just because nearly everyone on this forum uses a particular ECU it does not mean it is the best.

Most of Amberleys and Racepace’s GTR customers are not members of this forum. The GTR owners I met at Amberly that were running Motec’s have never heard of this forum nor do they want to be apart of this forum.

From my observation the more lucrative owners of the GTR population do not frequent forums on the internet. It’s a shame! Because I think they are missing out on being apart of a pretty good community for one and secondly we will never hear how their Motec powered street GTR’s perform. Shame!

I could talk till I'm blue (as could other members) in the face as to why the PFC is the better option but it still doesn't seem to sink in.

Oh well.

Yea! Well I’m sure people with Motec and Autronic’s can talk till they are blue too. But even if we do, we will be cut down by people that want to profess their love for PFC’s. I’ll draw your attention to the Autronic thread that was on here a few months ago.

http://www.skylinesaustralia.com/forums/in...553&hl=Autronic

The topic clearly stated “Autronic Ecus, What are peoples opinions on them?”

Instead of a thread about Autronic systems it became another PFC thread. This thread could have been a great way for people with Autronics to trade information and help each other out. But we didn’t get a chance.

End of off topic rant.

im still waiting for some fact

cheers

I had real issues running AFM on my street car hence why I ruled out using a PFC (DJetro had not come out at that time).

Is that a fact??

Well said!!!

if on a budget or dont wanna spend big dollars PFC is great..

Agree!

PM sent to stay on topic.

amen

As I have said in many other threads the PFC has its place as a great upgrade for an ECU but it is not the be all and end all.

If you look theres fantastic results with near every ECU on the market but these days Plug ins are the way to go in all but the wildest race car when powerfull logging becomes a factor.I Fit and tune a lot of PFC and Wolf plugins and like them both and as ppl know im very por Wolf but i understand the software and like the extra functions it has over the PFC

and the fact i can change them to suit other cars like the R33 GTS Version can fit in to Z32-R32-Ceffero etc as sensors and firing order ETC can changed in the software and i still have a lot of inputs and outputs i can use for other functions like launch control, NOS control inc a different map for when the NOS is turned on plus it can use any TPS so custom Throttle bodys etc are easy and things like being able to run low impedance injectors without adding resistors and dwell-discharge control so different coils can be used.Walky from these forums is fitting his GTS plug and play to his Rotory now his sold his Skyline.

local life time warranty and free upgrades is also a bonus.

Some Other shops hate them and if you are happy with using thier shop a Wolf is a waste of time as i said earler use what your tuners happy with .There is other options to PFC but there a well knowen and easy to use product thu a little basic so the choice is yours.There is other options to PFC but there a well knowen and easy to use.

Most of the RPM cars from what ive seen are using a PFC. Adam, Ben and a couple of others are excepetions... but for the most part, its PFC predominately.

Fact, indeed it is, but id be more interested to know why the problems occured
