SAFC II INSTALL! for all the newbies - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

xpl2007 · 09-15-2007, 01:41 PM

So i thought i write up a great install guide for the SAFC II to help everyone out. You need a wideband before to touch all the major settings so this is just how to install on a sr20det and get your car running to the shop. AEM wideband is needed to see the lean and rich spots.
Enjoy!!

Diagrams:
http://www.apexi-usa.com/pdfInstallation/15.pdf <---Instructions in Japaneses just update your adobe. READ IT ALL!!!

http://www.apexi-usa.com/pdfWiring/7.pdf <---Wire install! READ IT ALL!!!

http://www.innovatemotorsports.com/r...ecu_pinout.php <---ECU Pin #s for any car!

http://www.zeroyon.com/index/content/view/33/47/ <---Diagrams that will help you out for the pictures help!!

Basically its this:
SAFC II STOCK ECU
White wire - ECU pin 16 - white wire - MAF Signal Input from MAF (You actually cut the ECU's wire in half)
Yellow wire - ECU pin 16 - white wire - MAF Signal Output to ECU*
Grey wire - pin 20 - white wire - TPS
Purple wire - pin 27 - white wire - Knock Sensor
Green wire - pin 3 - yellow/red wire - Tach Signal
Red wire - pin 47 - black/white wire - Power
Black wire - pin 39 - black wire - Ground (Further from ECU 1cm from brown SAFC II wire)
Brown wire - pin 39 - black wire - Ground (closer to ECU 1cm from black SAFC wire)

Leave me some score points and feedback if you like this totally helped me out from some dk head to install it on my car. Also solder and heat shrink wrap all wires!!! No other way! NO C clamps or cheap ways to wire it to your ECU or you will be sorry. The SAFC II and your ECU need VOLTS and always has to be the same!
