Safc2 Install

[kidafa]

Hi All,

Got a SAFC2 to put into my Series 1 RS four.

All diagrams and manuals i can find on the web for it are wiring diagrams for the SAFC1 not 2. The 2 has a few extra wires that im not sure to do with.... Does any one have a diagram for the safc2's loom?

Also on the apexi website it says I use the N-6c ecu diagram for the pinouts (From here http://www.apexi-usa.com/pdfWiring/7.pdf) But it doesnt have the knock sensors labeled?

Some quick replys woold be wicked cos I wanna get it in thisarvo!

PS ive searched

[kidafa]

found this :

Red - power

Green - rpm signal

Gray - Throttle signal (TPS)

Brown - Ground

Black - Ground

Yellow - A/F Output (this goes towards the ECU)

White - A/F Input (goes away from ECU)

Blue - can be used as O2 sensor voltage meter. Hook up to one of the primary O2 leads.

Pink Not used (Used on Karman vehicles)

Orange Not used (Used on Karman vehicles)

Purple - Knock

Looks good. Im not going be hooking up the pink orange or blue correct?

Now all i need is a ECU pinout diagram with the knock sensors on it

Ok. Looks like Apexi have removed the manuals for the SAFC2 from their site. Some other place has them hosted here: http://www.kaichia.com/media/safc2_wire.pdf

Im going to go by the cpu pin out from their. Sound good?

yeah, the N6-B diagram.

thanks for that QWK32. Thanks the diagram I went with

Its all installed and it turns on ect. As im yet to get to the dyno (will happen in a week or so) What do I need to do so that it doest adjust the mixtures yet? I have purchased the unit second hand so I have no idea what the current tune/tunes it has on it. Is their away i can completely reset it or something?

Once it is reset will i need to do the car setup eg hot wire ect so that I can drive it? If so some one like to share the love with the settings

Cheers,

Chris

yeah, if you want to reset the safc you can. or if you think the settings are correct and just want your mixtures to be unaltered you could go into the correction maps and set all the values to zero.

on page 60 of the manual you used from that website, is how to do the initialization (reset) just in etc. and scroll down to initialization.

to just set all the correction maps to zero go into "Setting" and in Hi-Thrtl and Lo-Thrtl set all and values on the map to zero.

if you do the initialization, which is what i would do. the settings you need to set to get the car to run are: go into etc.

Sensor Type ->

Sensor No: HW and 04 in and 04 out

Sensor Calc: 01 in and 01 out

Car Select ->

6 Cyl, and the Thr is the arrow pointing up and to the right.

Dont worry about Dec-Air and on Pg 30 is how to do the Knock Setup. Just so it displays the correct value, not needed to run the car though, you could get the tuner to set this up for you if you want.

for the throttle setting the aroww only points to the right up or down not to the left. so im guessing you mean right and up?

Also just wondering why i hvave read different sensor no's for in and out and snsor calc no's on the forums

eg check the basic settings post in this thread :http://www.skylinesaustralia.com/forums/Safc-Install-R32-R33-G-t85232.html&hl=safc+install

[QWK32]

yeah sorry, up and right (i edited my original post so its correct). the Sensor number is for what kind of airflow meter / Map sensor you have. So, for all skylines/stageas with RB engines running stock AFM's it is 04 04, except for GTR's which is 03 03. if you have a Z32 or Q45 Afm it is different.

eg, for a Z32 you need to set it at HW 02 in and 04 out. 02 is the Z32 afm code, so you are inputing a 02 type afm signal but want an 04 type afm signal for your RB engine ECU.

and the different Sensor Calc numbers are for multiple AFM applications or for running 1 AFM on a multiple AFM ecu. so for non-GTR RB engines it is 1 afm signal in and 1 afm signal out, or 01 01.

Too true. I've got an SAFC2 coming and I need all the homework. I'll be installing it myself also.

[kidafa]

give us a yell if you need a hand ruby. Should be ok. The info in this thread is all i ended up using. Were lucky I found the manuals for the safc2 as their no longer hosted on the apexi site.
