for those of u who have managed to work it out :starwars:)

im looking at the english safc.pdf from apexi...

and looking at the safc2 manuals in jap...

and too be honest.. i have nfi

are the wires in same color configuration as before?

there are an additional 2 more....

is it possible to just wire it up as per safc1 diagrams..

and guess work the others? or is that bad for the ecu health? im working on the assumption here that they still are still color coded the same way..

yellow - air out

white - air in

brown - ground

red - power

green - rpm

pink - ?

orange - ?

purple - ?

blue - ?

grey - ground ?

by the looks of things the ground has now moved to the last pin.. near teh IG power?

that leaves the last 4 connectors to the 2nd and 3rd pins looking left to right on the n4-a diagram..

perhaps better still... for a 93 series 1 r33... how to? :)

cheers

Hey dude, i also have an AFC-2... your in luck aswell... i spent hours friggen translating the colors of the wires to match the diagram in the manual... most of the wires are the same colors and have same jobs as the previous SAFC when translated they are...

Red = IG power

Green = RPM signal

Brown = Ground

Black = Ground

Grey = Throttle

Purple = Knock sensor?

Blue = Used for twin turbo set ups with the extra yellow "Y" shaped wire provided, where there is two AFM signals that must be intercepted

Yelow = Air flow/Pressure signal OUTPUT

White = Air flow/Pressure signal INPUT

*Orange = Sustitute Air flow/Pressure signal

*Pink = Sustitute Air flow/Pressure signal

****Not sure what these are used for**** (possibly non turbo set up? Not sure.

K now to use these colors... from left to right on the N4a R33 GTS-t ECU diagram i have narried it down to:

1) Green

2) Purple (check ECU for empty pin cos it can be either of the two pins

3) Air flow wires (white and yellow)

4) Grey

5) Red

6) Ground (grey and black)

Only thing i can't work out is what the pink & orange wires are for... i know the blue is used for twin turbo set ups where there is two air flow/pressure signals due to dual air flow meters, but the orange and pink wires don't seem to come up... i think they are used for non turbo aplications maybe?

Also the only thing i have not worked out is why there is two possible wiring diagrams on pages 8 & 9 of the wiring book. The one on page 9 uses the pink and orange wires as the air flow intercept wires where as the diagram on page 8 uses the white and yellow configeration. Not sure why there would be two?

Let me know how u go.

hey there :P

i had a go and wiring this sucker up today...

and lets just say.. i didnt get very far...

that n4-a diagram isnt the same as my car...

ahahahhaha.. my ecu is missing that wire as shown in the diagram.. [edit] thats the rpm wire.... stupid thing

i've given up.. haha.. i think i'll just pay someone to fix my mess.. and get it tuned.. i swear it isnt meant to be this hard..

The MAF(Hot wire type) and AFM(flap door type) use a voltage signal from the meter to the ECU.

The Karman type sends a frequnecy.

My guess it that White and yellow are for most of us.

The Pink & Orange are for the Kar/Vortex guys.

Damn i wish took i Japanese in 2nd'ry skool :)

a round about process but one way is to copy out the acrobat text and paste it on to the altavista language translator

http://babelfish.altavista.com/

you will need full version of acrobat and a program to break the encryption on the acrobat file, both are available on the net.

    • Hey @Butters, did you end up getting this clutch in ? I have just ordered to a uniclutch track to go in my getrag 6 speed that’s in my BNR 32     
    • I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive
    • Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?
    • This came quicker than I thought. It ain't even 2025 yet.
    • I somehow quoted my post instead of editing it. I regret nothing.
