power fc in a R33

[chowetime]

Looking to try and find a reason for not putting the power fc into the car, I have so far found a lot of reasons to put it in but as yet have not heard of anyone say anything negitive about them... I know this is a weird thing to be asking but would really like to hear from people if they are unhappy with the unit ie: if it had cold start problems ect..

empty wallet

it will feed and promote your addiction to car modding

Other then the wallet being a little lighter, it would be the best investment for your engine.

It's hard to come up with a reason not to get it, unless of course you own a Auto and then the power FC want work well with the auto ecu.

thing is, there are no real problems at all.

You have to ask yourself...

If there were problems, why are soo many people wouldnt be using them?

It doesnt have as many options as a $3000-$5000 ECU, but for $1100 or so delivered... cant go wrong

I have been down the modifying route before with my previous car and modding a car is a lot fun and very satisfying, so I am looking at doing it all again but with a better base - R33

the reason for me asking this is that my previous car was the first car that was fitted with the Greddy E Manage and due to it being a new type of air fuel computor no one new how to wire it into the car then the next job was to try and find someone that could tune it but it got done and it did take several weeks due to having to get various injector harnessess and the program which had to be translated from Japanesse to english and then it was discovered that we needed a cable to go from the laptop to the GReddy... I could go on about all the things that went wrong and all the things that had to be changed so that the car would run like a factory car but with all the benifits of a modded car - speed

I was just so surprised as to the pricing of it to be so reasonable compared to other full computors such as the Motec - Wolf 3D - and others and just figured that you get what you pay for but I am not fond of paying for stuff that I don't need or won't use either

I have however just finished reading an article about the PFC and that you don't need the hand controller to do the tuning and that the people that will do the tuning can do it via a laptop which will give a better tune now I just need to find a place that can do it this way

[R31Nismoid]

it wont give it a "better" tune at all.

Everything can be done with the H/C

You have to pay extra $$$ if you want the datalogit software, a few more options but certainly not a better tune as such.

The odd place will have it... But most places wont as above ^^ the H/C does it fine.

These days, when you buy a PFC, it actually comes as a complete package... so you get the H/C no matter what (thats included in the $1100 i said before)

having to keep the AFM would probably be the worst thing about the powerfc, but some people like them so its up to you.

i also purchased a power fc

do i need to upgrade my afm to z32 instead of stock?

[JCMarshall_Law]

I don't own one but I have looked into them a bit, By all accounts you can do a good job of tuning the car with them but they are lacking a few more advance features that would be good, such as: (please correct me if I'm wrong)

- No onboard datalogging

- you have to pay extra (a lot extra) for the laptop / PC program for tuning and datalogging

- No map sensor,

- No traction control

- no auxillery power relay which can be triggered by various engine parameters such as RPM, inj duty etc. (these are usually used for water spray, NOS systems etc)

- The fuel map resolution is not real good.

But like was said in an eairler post for $1100 they are great value and will just about everything you need to do in a street car.

If you want features buy the Motec M800 they are brilliant bits of gear, they will everything you could dream of. Most (all?) of te V8 teams use the M800. I have had a bit of experence with the M4 pro and even those units are excellent - prob is they are definatly not plug and play units (like the PFC) and you pay throught the nose for them.

Ok.... so it won't look after the MAP sensor... I would imagine that would have an effect the way the car idles which could be sligthly higher than factory then? I have also noticed that people are changing there AFM to the Z32 why is this is the current stock one not adequate for tuning...

Not having traction control which I am now starting to get very fond of (due to heavy right foot) could make life interesting....

Maybe the SAFCII/GReddy might be a better option after all as I am really just after better fuel economy due to the car running very rich.... and would like to keep most options on the car.... except the speed limiter

http://members.dodo.com.au/paul/docs/power...powerfc-faq.htm covers a lot of the questions you guys have asked. also nothing majorly wrong with using airflow meter. youll get overall better idle and tuneable support instead of using a map sensor. just need to upgrade the calibration of the afm as you move up with power. sorry im not trying to be a know-all im certaintly far from it just some of the not so technical guys may be wondering what exactly you do and do get with the powerfc, a lot of it is covered in the faq. of course if any of its wrong let me know and ill correct it

[chowetime]

I actually tried the site you mentioned before posting this question up but was unable to get the site for some reason... but you are right I certainly don't know anything when it comes to turbos ect... ask me questions about my previous car and that is a different thing altoghter )
