I bought an apex'i s-afcII lastnight and now I am trying to get the wiring diagram off there site because the instructions are J-spec On there site it does not list the maxima as a choice, but it does list the cefiro....for the guys who have installed this or know, did you use the directions from the cefiro or from something else? Thanks.

wiring instructions are on fastmaxima.com

 

did you use this site to wire yours? The only reason I ask is because on the apexi site for the cefiro (A32 chasis) they are showing a different diagram for the N4-a....sorry if this is a dumb question but does anyone know which one I should use for sure? Thanks.

use the one on that site....I've used to to wire in both the AFC and Emanage on the 4th gen

 

guide yourself by the pin structure in the FSM. YOu need RPM signal, MAF signal, throttle, power and ground. Its a total of 10 wires since you have to splice two. Not hard just time consuming.

 

ok, I will use the one from the site...thanks for everyones help....jay, I dont have the fsm so I will just have to go off what the site says

 

ok, its all hooked up except the blue wire...I think it maybe for the O2 sensor, but I am not positive....does anyone know if you are suposed to hook the blue wire up at all? (this is on a 98 GXE) Thanks.
Carson

--also if anyone has any advice on where I should set the settings for the best performance with all bolt ons I would appreciate it.

 

use the blue wire, but does anyone know which o2 sensor to tap for an A/F gauge?

 

ok well where does it go?....it is not in the pin out on fastmaxima....anyone?

 

Read the text at the bottom.

 

Ok, so the blue wire goes to Pin 51? I am just wondering why it is down in a footnote if it is actually used. If I am correct in saying that it sould go to Pin 51 and Pin 51 alone could someone please let me know. Thanks.

Its your choice which one you hook up to, left or right, either one will work or do, not both.

It only gives you a voltage readout and you have to interpret the A/F from that.

There has also been some discussion that I have read from other sources that say it interferes with the signal going to the ecu. Thats why I put it at the bottom, its a user try it at your own risk option.

You should also understand that these are narrowband sensors and not accurate for boost a/f levels, so I wouldn't rely on this alone or use it to adjust my S-AFC.

 

Thanks...............
