^^ there is no difference i have personally taken a PFC out of a S2 R33 and put it in my S1 R33 the differences are with the turbo on the engine and igniter's on the coil packs for the S2 the actual ECU handles the engine the same way

hey thanks man for clearing that up for me, good to know that someone has tried it too, so once again thank you, you are a legend :)

Hello. The website that hosts this FAQ has been closed as I got sick of it being hacked by Wordpress exploits which means the link in the first post won’t work. I can add up a PDF copy of this do

Hey! Some fresh up for the thread. I've developed adapter for Power FC that can feed all the ECUs data to your iOS/Android. If somebody still interesting in such a stuff in 2021, I can start

Had a search through this thread and cant find an answer, basically i have just had my power fc installed and instead of having to take the kick panel off every time i want to check something through the hand controller i would like to leave it in the glove box, is there anyway to lock the keypad so that buttons dont get pushed by other things in the glove box?

Hi

just after some help from anyone

I just got the power fc boost control kit for my car.. its the right one the A001 or whatever.... Now i know the map/pressure sensor plugs straight into the power fc, but where do i plug the actual solinoid into?

From what ive managed to find it seems as though on an RB25 you plug it into the stock wiring loom where the stock boost solinoid went, but i was under the impression that this provided constant power but no earth till the car hit 4500 rpm... Can anyone else help me out with this?

car is 1994 R33 GTS-t With Power FC (standard) and hand controller. PM's welcome :)

Cheers

Callan

W0rp3D - hand controller is fine to go in the glove box

Boostin96 - the plug goes straight into the standard boost solenoid plug its near your power steering reservoir

Cheers mate

so is this pin on The ecu slightly different to what it does on the stock ecu?

cause i thought it just earthed at 4500rpm?

ahh i see

so it basically serves a different purpose going from std ecu to power fc

eg. Stock ecu - earth at 4500rpm

Power FC - open solenoid at x amount of boost

or something along those lines anyway.....

its covered in the FAQ

there is no N/A version for R32 - you would need to buy R32 RB20 PFC, which is ap engineering

it will need to tuned before it will start correctly, as it will assume GTST AFM, Injectors and engine maps

that being said, you could correct it manually on the hand controller to make it start and drive OK

then you could drive to the tuners if it was a long way away or you couldnt wait

Hi Paul,

Ok, so I got my R33 RB25DET back from the tuner with a new turbo installation with the following:

Garrett 3037 turbo

Top mount manifold

SARD 550cc Injectors

Bosch 023 Fuel Pump

FMIC

Profec B Spec II BC

PFC

and more supporting mods...

Although they done a good job with the turbo/piping installation, the tune im not too happy with and need some advice on.

My problem is, when my car is cold, the revs surge from around 1300 to 1800rpm (this goes away when the car warms up), the tuner said he had no idea why this is happening and mentioned that the PFC doesnt have a cold start tuning option (if this makes any sense)?

The other thing he said was at high revs it knocked too much, so he reduced the timing right down to around 15deg IGN timing and now its very sluggish. He said that getting a high flow cat might fix this problem?

Im not too cluey when it comes to tuning and ECUs, so if you could shed some light on this situation it would be appreciated.

Cheers.

Mick

PS. I just checked the Injector latencies on your PFC docs, and im not sure if the tuner set mine correctly, they read 70% and -1.30ms, souldnt they be 67% and +0.052 for SARD 550cc in RB25DET?

very quick question

got mt PFC installed into my R34, ever since then my engine light wont go off the dash :) asked the tuner he said it's running fine etc and has no idea why it wont go away, he said the only time it goes away is when he loads a fresh map onto it but then comes back straight away ?

      R34 GTT air noise?

      By GTSBoy · Posted

      Boost leak or exhaust leak. Boost could be from anywhere, including manifold/plenum gaskets. Exhaust is frequently head to manifold gasket or from manifold to turbo gasket. Often caused by missing nuts or broken studs.

      Wheel offset has me confused.

      Check for spacers on the front, in case they've been pushed out a little to try to match he rears better.

      I should clarify that the previous owner put the wheels on, so Im not entirely sure what he bought. I was searching the Rota page and found these two as the only matches. It did not occur to me that perhaps they sell these wheels with different offsets. I guess the best way to solve this is to take the wheels off and measure them from the inside to be sure.

      By Kinkstaah · Posted

      The offset doesn't really have anything to do with dish directly. I mean it kind of does but it also doesn't, it's only tangenial. The offset is purely how much offset (get it) the mounting face is from the CENTER of the width of the rim. I.e, the mounting face would be directly in the middle of the 9.5inches if it was a 18x9.5 ET0 rim. Given it is a +12 rim, the mounting face is 12mm further away from the center (to the outside of the car). Your fronts are +30, so the mounting face is 30mm further away from the center (to the outside of the car). I would wager this doesn't look right, because most skylines generally have the same with guards front to back. So I'd think your fronts look significantly more sunken in than your rears. I'd wager by about 18mm, or so.

      Wheel offset has me confused.

      By IXMandalorianXI · Posted

      My '96 r33 Skyline has Rota GTR, 18 x 9.5 inch, ET30 on the front and Rota GTR-D, 18 x 9.5 inch, ET12 on the rear. (Put on by previous owner) The 12mm offset is throwing me for a loop. Is it due to the "deep dish" design of the wheel that the offset it so low? Or is it actually that low on the rear normally? If I were buying a set of new wheels, could I put 30mm offsets on the rear and reasonably expect them to fit? I have GTR Brembos and 370Z rotors (355mm/350mm) if it matters. Thank you.
