Would you like me to pull mine out and have a look at what model's running in my car Nick?

Why PowerFC Nick? Just for ease of installation?

Just out of curiosity I'll jump in and ask a question.
Has anyone used the N/A version?
Was it a worthwhile investment?
Thanks.

Nick you can use either of the following versions of Power FC:

414-AT006 (for N/a ~2001)
414-AT010 (for Turbo `~2001)

the difference is in the base map, if you get the one to suit the turbo (414-AT010 ), it has a far friendlier basemap to plug and run to get it to the tuner. the other (414-AT006) has a basemap to suit N/A but i believe it to be the same ecu as 414-AT010 other than that. You still need a maf sensor

(yes this does contradict what i wrote earlier in this thread a few years ago, but i have not seen anybody in an altezza running an out of the box power fc that can run it on any kind of map sensor alone. i have learnt alot since my earlier postings due to my own experiences)

personally i have no problems when running the power fc (i run the 414-AT006 on a boosted application for over 2 years), but it does have some very serious limitations, and if i did do it again and wanted more power than i currently have, i'd be going with a link ecu in a heartbeat.

depends how you measure "worthwhile"

Any tuneable ECU (Power FC, Link, Haltech etc) when combined with other supporting modifications allow you to maximise the potential of your entire package. Obviously the gains are all realtive

I have not experienced an altezza thats only mod is a power FC ecu so i cannot comment on the difference it made in that situation.

Can you elaborate on this Andrew?

I would love to go for a Link but the $$$ just blows things out of the water, the Storm G4, harness, airtemp sensor, wiring] and for some of the dash to not work etc just seems to be a bit too troublesome and costly for me.

Seemed the PFC would be alot easier being just to drop out the old ECU and throw the PCF in and tune >.<

Maybe I need to re-investigate this?

Really depends what you want it for - I'm happy with PFC, but then again I don't need datalogging or anything fancy really... some form of knock control would be nice though!

For that sort of price, why not go link g4?

If I could get a Link with the air temp sensor (why they sell them seperately is still beyond me!), harness and all the wiring ready to tune for just over a grand I'd go lol however that's not quite case with the G4 ;)
PCF is just drop the factory ECU out, PFC in LOL

Exactly. PFC is buy, drive to tuners, unplug ecu harnnes and plug into PFC hand tuners keys and walk away.

I know a guy that doesnt even charge to install PFC when you get a tune its that easy.

G4 is buy ecu, buy map sensor spend a crap load of time rewireing your harness to suit give up because it doesnt work and have your tuner do it for you (at considerable cost), find a tuner (like finding a needle in a hay stack in aus), tow car to tuner, spend extra on tuning because it doesnt come with a base map for an altezza with vvti recieve car back and grumble at things not working like they should (dash lights climate controll ect)

All this adds up to three fold what a pfc would cost to buy install and tune.

Still waiting on limitations of a PFC though as im in the same boat as nick it seems

414-AT010 (for Turbo `~2001) is what im using.

Using the MAF sensor and it runs fine.

Only thing is when you increase boost the voltage graph needs to be squeezed up as you still only have from 0-6 volts but more boost (flow) to cover. So not quite so easy to get running perfectly.

(Prob doesn't really make sense but oh well

If I had the $$$ and the time I would probably go for the Link G4 aswell, just for the fact that it runs a MAP sensor to 2 bar standard and would be alot simplier to tune.

Makes a bit of sense :D
Running OEM MAF sensor or an aftermarket unit?

Running Greddy one from the turbo kit. Its 3" and so is the intake of the turbo but the piece of pipe in between is only 60mm so been thinking of incerasing the pipe so to get rid of the restriction.
We'll see how it goes :) (Work in progress....)

Sounds good, still just the factory RS200 sensor?

Saw the Apexi 3Bar Map sensors are available too and are plug and play with the D-Jetro units! And also have a boost control unit too!

Keep getting the odd eye @ work as I normally campaign and push for Link products products now but might be fitting a PCF haha

I would go to a Link if I could do it again too.

If I was stuck with the PFC I'd stick to OEM MAF and MAP rather than [f**k]ing around with all the different MAFs and now being stuck with the 300zx AFM, seperate air temp and MAP. All those miss problems I had were down to the 300zx AFM.

unless you are running a air box ,tuning it to tps would be better

The strengths of a unit like the PowerFC are also its main weaknesses. It isnt as versatile all round as a link but that may not be a problem for you if you dont plan on needing more than any of the factory components can provide (ignition config and squential injection come to mind) out side of configurables like injectors and MAF

All comes down to what you want to achieve with the build you are planning.

Im no expert on tuning ECU's so I dont really really know the strengths and weaknesses of the power fc or the link.

I plan on building a low comp (9;1) 3SGE beams (forged bottom end stock head but eventually will get bigger cams that still work with vvti) with a td04 turbo, (eventually going GT3071 with custom collector manifold, external waste gate and 2.5' exhaust) custom inter cooler, with 1000cc injectors on 98ron hoping to get between 200 and 220 KWatw on 10-14 PSI (if the turbo can get to 14 that is).

Is there any benefit for myself to go a link over a Power FC? (Im also in Australia and there is hardly any link tuners here apparently)

Also I know MAF systems have alot of trouble in turbo charged cars. If you could start over what type of system would you go for? MAF, MAP or AFM or a hybrid?

Sydney. I know people who think they can tune any ecu too but I would rather go to someone who is factory trained, I learn from others experience...
