proxlamus© Posted March 23, 2005 Share Posted March 23, 2005 Apexi S-AFC install.. I am getting close.. just need some help As you guys may or may not know, I am attempting to install this Apexi SAFC to work on our older Z cars with the factory ECU.. and here is where I am stuck.. here is a thread with tons of info about it.. and stuff http://forums.hybridz.org/showthread.php?t=87665 http://www.zcar.com/forums/read.php?f=1&i=558520&t=558520 Anyway.. I scanned the Apexi S-AFC manual's diagram, and wrote next to each connection what ECU PIN and what color the wire should be. I also scanned the 1978 FSM for a diagram of what our car really has, compared to the overly simplified Apexi S-AFC diagram. What I discovered is.. the Throttle Signal or TPS basically connects to 3 PINS on the ECU... IDLE - Pin 2 and Pin 18 (black wire) FULL THROTTLE - Pin 3 and Pin 18 (black wire) and the Air Flow signal or AFM connects to 4 PINS.. *sigh* Pin 6 and Pin 8 (black wire) Pin 7 and Pin 8 (black wire) Pin 8 and Pin 9 (black wire) This is obviously a problem, because the Apexi S-AFC only has the TPS and AFM signal connected to one wire.. not 3 or 4 for each one!!! Anyway.. can anyone give me a good idea on which wires I should connect this to.. to get it running?? Quote Link to comment Share on other sites More sharing options...
