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..

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 :rofl:

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

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 :rofl: (thats included in the $1100 i said before)

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

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 ;))

    • Because all parts that are put into your papers usually are assigned a badging if they did not come with one. So other people can just check that badging to tell if it is the parts your papes outline. But my pipe has NOTHING on it whatsoever. No idea why this even passed as a Mines pipe to begin with. I see this going two ways: -nobody cares and it's a non-issue, but that is unlikely -the pipe will just have to be assigned a bagding, for sake of argument, a Mines logo, and the papers corrected accordingly If it interests you I will post what the actual solution ended up being. All I care about is that it has to sound equal length and nobody can screw me later on because of a pipe being illegal.
    • The fasteners to the pipe are not subject to TÜV I guess, if we really start putting nuts and bolts through technical tests I'm going to hang the people responsible and then myself. Usually on a modern-ish EU normed car, you would just replace the pipe. Because if you start hacking away at it and welding new pieces on the cops will definitely find a reason to tow your car. That is just how it is sadly. On old cars and imports with no clear "standard" stuff like that won't matter too much. Most cops or inspectors probably won't even really know what they are looking at. But there is experts for this stuff even among cops, and some of them know the rules to a T and even have extensive knowledge about many vehicles. For "just a pipe" to be legal it usually is included in a set of parts, like a complete intake kit or a full exhaust. For example my exhaust needs to pass a noise test, meaning they have a standardized test track with a set of instructions and they run the car through there 3x for an average noise value that is 75dB(a) at point x of the test track. If it's above that, fail. For a turbo setup to be put in your papers you have to do dyno runs, emissions testing etc. So quite costly
    • Would this not be the same for the exhaust you've posted up?  If your exhaust volume and emissions are fine, why does the brand of pipe matter? 
    • The issue is more the fact that there is inspectors that deal with japanese cars a lot and they might know what a real Mines pipe looks like. And then they're gonna get antsy and not pass your car. But I'd have to talk to one of them about this, because you know as well as me that it's just a damn pipe and it effectively doesn't do anything. As I need to have my GT2860s and my exhaust setup (and the increase in HP) TÜV'd anyways maybe they can just correct the entry in the papers or assign a badge to the front pipe. I'm no expert either though, will inquire about this.     Thanks for the insight. Not sure if having a custom made pipe is good or not. Will find out in due time I suppose. Would be kind of funny if this was made in Germany though.
    • See this is a really tricky topic as technically the same rules apply to all cars but for cars but there is a difference. If you want to modify a car like the Skyline which never existed here you have a bit more freedom as they do not adhere to EU specs anyway. Any modification you do has to be in dividually checked anyway so as long as one of the inspectors think it's ok and within the TÜV ruleset you can get stuff like a top secret rear diffuser put in your papers. Which frankly would need a shitload of tests and certificates for EU spec cars, like a 2010 BMW M3 for example. But if you DO run these tests and all tests come out ok (safety stuff for the most part) there is no problem running such a part legally. It's just way too expensive to do for a single person on one car. The most touchy parts are emissions related mods, like an exhaust, turbos, air intakes. If it makes noise or alters the carbon emissions it's essentially illegal until you prove it's not. Meaning it doesn't exceed noise limits or have worse carbon emissions. I'd say for hoses if you replace them same same it doesn't matter what material they are or what brand you use. Same for nuts and bolts usually, they won't go and specifically check that your water hoses and some bolts are 100% OEM parts, that is nonsense.
