Pfc Cross Road Normal Or D-jetro

[Travis Trayhern]

well my tuner has quoted me $370 for a full pfc tune, i really dont need all the fancy lanch and anitlag gizzmos and i dont wanna wait for a heads up display then i have to spend more money to get that. its not a f1 car just a road/circut car im just abit unsure of change lol

[R31Nismoid]

That's a very good price for a tune, but then there is a bit of work already done, so reasonable in those respects.

Honestly, if you didn't have a PFC you could look @ all options, but you have one... why dick around with changing it when your tuner says PFC anyhow.

I personally would stick with the AFM's and upgrade them. Those nismo replacements are pretty bloody expensive though.

No particular reason behind my logic, I have owned both MAP and AFM tuned cars and from my experience it comes down to the tune.

Some argue that you can make airflow changes to AFM based cars without looking at the tune, but I always prefer to get things checked and trimmed anyway.

Re: Vi-PEC arguments, I think I am going to look at one of these shortly for my rally setup... the damn r32 Gtr PowerFC hiccup happens at least once a drive - very unhappy with it.

[R31Nismoid]

You must be unlucky, ive got one that pops maybe once every 400-500km's

[Travis Trayhern]

cheers i will have a look for some cheap z32 afm's and do it that way is there anything i have to look out for with the z32 afm's?

[R31Nismoid]

They dont bolt on, you need an adaptor i believe as they are larger than a nismo/stock AFM

plus, dont get 2nd handies... better off to buy new.

[Guilt-Toy]

Waste of time?

I think you don't have an answer, or the answer would be something like there is no real major difference. Minor time, ye. Major anything, no.

Question....

How many Power FC and Vipec's have you tuned Ash?

[R31Nismoid]

I dont tune, i never have.. And thats not the point, nor what was asked.

Could the reason you cant answer the question be because there is bugger all difference without the add ons??? You know, the ones you really don’t need and stuff?

Then say, that there are no actual limitations or world changing differences between the two?

Vipec (as you say, might be 30mins) & PFC (2hrs) but other than that you have offered nothing to suggest vipec is better than what the average punter needs (and remember, excluding the fancy addon stuff, that not everyone needs).

You took this thread off course from the first post. He only needs to upgrade AFM's and its finished. The OP does not want any fancy shit. Just something that does its job.

Changing the whole ECU setup, full retune and so on is not a good reccomendation.

In all seriousness its like saying change the turbos from HKS GT-SS to the Garrett -7s/9s... just because there is a minor difference in how they work and price.

If you could answer the actual question about the limitations of the PFC vs the Vipec in relation to the mapping, tuning and then drive home with no fancy addons that you dont need...

That would be good, because there isnt much that you've added to this thread other than some wayward pricing as a bit of a smoke screen because he already has a PFC and everything else, and the offer of a cheap tune adjustment to boot.

If you don’t want to answer me, that’s fine. But remember the question is not just being asked for me.

Plenty of other people read threads, and im sure some of them would like to know what limitations there are also.

I wouldn’t be surprised if there are a few people interested by your comments that would suggest the PFC has severe tuning and mapping limitations. And I say suggestion because you wont answer the question about it which begs the question of WHY?.

Ash my Power FC was tuned by one of Australia's best GTR tuner's...the bloody thing would cough and carry on...after a burnout wouldn't return to idle and would often stall the car (AFM's are the shiz eh ?) having to roll the foot over to keep the thing running so i could get into stage before the 20sec rule came into play. You say 'oh thats a race car though?...the same thing happens to light tuned Power FC GTR's on the street after a bit of a thrashing and then hitting the anchors pulling it up at the lights...mine did and so have many others ive driven or been a passenger in. The return to idle on a Power FC is piss poor. What about the choof choof choofing when larger low-mounts are used etc....another short coming of the AFM equipped Power FC.

I was sick of that sh1t...so ive upgraded...nothing fancy add-on stuff there...i just needed my car to run right without the well documented hiccups the Power FC has.

Yes a desktop computer that was designed and built in the 90's will surf the net, send emails, type word documents etc...but the latest technology does it so much better, smoother, faster and more reliably. Its the same with all technology...why is your beloved Power FC any different?

We certainly have strung you along nicely for someone who cbf'd having an arguement in post 4...lol

Mine returns to idle fine, always has, RB25 & RB26 versions.

But if return to idle is all you've got, you'll know why i'm similing right now

larger meaning GT-RS? 2530's dont do it setup correctly.

I was out @ post 4, but then the silly rubbish/points came into it, which still haven't been answered i see

I dont see the point in people being led up the garden path for no reason. Its not right.

The Vipec is an alternative. Thats all.

Dragged another post out of you Ash...lol...you make it so easy. Its like shelling peas!

[JAGR33]

i just needed my car to run right without the well documented hiccups the Power FC has.

Where can we find these documents???

I've never come across any hiccups or gremlins with the powerfc, nor have i heard anything from people in regards to this.

There's no doubt the vipec is a capable ecu with all the fancy hooha, but i guess its still fresh and needs a few years to prove itself...

In this case i don't see why the powerfc should be ditched for the vipec where a simple afm upgrade will suffice.

Don't you people realise that Ash is always right!!!!!!!!!!!

Here's one i very quickly found...the UK guys have a few threads also.

Got another 'Racepacer' involved...lol

Yes Ash is always right...but also is a good guy and lots of fun to toy with...hehe. s/s

Not everyone knows when your dribbling shit

Aww be nice...its nice to be nice

Jack 4MB of logging would actually be quite helpful for you.

Every single person that has had a Vi-PEC installed makes the comment of how much better and smoother it runs the engine...quite a few of these are old Power FC tragic's like yourselves.

Its human nature to be scared of change and something new...but its ok guys to you let yourself go and fly high on the wings of change.

anyone do a comparison between the wolf v500 and the vipec's. i've got the wolf and am more then happy on if (125rpm tuning increments FTW) just curious

hell i'm just glad that more and more people are getting over the "OMG it's a power fc it's the best in the world"

[paulr33]

for the average mild street car i think the pfc would win hands down

in terms of cost, tuners, plug in and drive off, features, the simple hand controller, and its bulletproof setup

for a well geared up track car with specific requirements

like drag junk and what ever other fangdangle stuff you may require

there might be better options.

the apexi documentation clearly states idle issues will occur if you modify

the throttle body setup, incorrectly use the map sensors, or make other changes

and its a well known fact that multiple throttle bodies and map sensors

are a known gotcha in many common ecu scenarios

and yes there might be some ecu's who handle it differently, but its a known gotcha (map & ITB)

- in relation to sucky idle & chuffing etc - was it djetro & ITB?

Yes the world is a very clever place full of very clever people and believe it or not something has been produced in 2008 that is better than something in the 90's. I know its hard to grasp but yes its true.

Paul the dealers load up a start-up map configured to their set-up (injectors turbo rev limit etc) that sh1ts all over the mega rich base map that comes with a Power FC, its a straight plug in (mind you it has to be fitted into a STD ecu case which is a job that takes me a few minutes). Its tuned far quicker than the Power fc with lees dyno time and power runs needed to get an optimum tune out of it...no more flogging the car on the dyno to get the Power FC style tuning right. Feature's..what features does a Power FC actually have?..ohh it displays a little light on the dash when your engine is destroying itself. The Vi-PEC has actual knock control that deals with a situation and will actually save an engine not let it keep destroying itself like the good ol' Apexi does. A dash interface/engine monitor is not too far away and will have far more features and uses than Apexi's little plastic toy. My car ran afm's in both multi throttle and single throttle applications..no d-jetro. You are yet another one who has no experience with the Vi-PEC yet you are claiming a "hands down winner" i thought you were a little wiser than that.

These guys have no experience with tuning, have no experience with the Vi-PEC ecu and id say have not been open minded enough to actually listen to someone that has gone from Power FC to Vi-PEC as many guys have done. Ahh well the head in the sand approach can sit with them while i enjoy a car that runs better and smoother with my new ECU.

yeah i went from a pfc to the wolf. major difference. i got out of the tuning real cheap though as my mechanic was having a play with it. we where interested to see the results as no other mods where made except the ecu change. even kept the same pods and first tuned with the afm's just for comparisons sake.

made more power, better fuel economy, better throttle responce, kept all the lovely features like idle up for air con etc. interestingly enough apparently with the wolf it can run auto boxes too.
