need help! APEXI AFC NEO
#3
it's really easy to wire in, just use the instructions and wiring diagram that came in the package, you will want to use the "toyota BB" ECU reference in the wiring diagram.
pm me if you need help, i had mine wired in about 15 minutes.

I have not done any wiring before and I'm having problems locateing where to attach the "ground" wire (Brown, Black) to the ECU (T12-a, diagram). I have all the other wires setup, but there is no ground wire located on the ECU harness where the diagram states there should be. Is there another way to setup the "ground" or am I missing something?

gains to be made if you have turbo / supercharger. for N/A motors very VERY minimal gains can be made, but it is pretty useful for monitoring different things, like air flow, throttle position, data logging, and battery guage, and a few other... i will check my ground wire, and see WTF it is connected, i did it a few years ago so i am slightly fuzzy. although there IS a ground wire coming out of the ECU you may want to search the forum for an updated diagram of the ECU for your year - mine is an 04 and it matched the diagram exactly. Both ECU diagrams are the same for XA and XB. i believe that APEX-I also has updated diagrams on their website. i'll check and get back to you.

i can tell you by looking at the diagram you have, it's incorrect. i will try to find you the correct one to use. i just looked on their website, and our engines are not listed on the Neo wiring diagram. you need to use the wiring diagram from the S-afc 2 model. i'll find it and send it to you or post it

also, the 2006 ECU has a different pinout then the 04/05 models. i am working on getting you the correct diagram. hope you didn't splice anything yet, the wires may be wrong i'm not sure how many are incorrect though.

here is the 06 pinout "i think" i am waiting for a source to 100% confirm that this is the 06 pinout for the 1nz-fe engine. Compare this to the diagram that came with your afcneo. I looked it over, and this diagram doens't show what wire the ground is, but i know its in there. you may have to use the process of ellimination on all pins that are shown in the diagram, but are not accounted for. use a somple multi-meter and check for ground against a good ground near the ecu, like a bolt in the frame, or your ignition ring. once you find the ground wire, it must be tapped in 2 places very close to each other, JUST LIKE THE INSTRUCTIONS SPECIFY, or the unit won't work properly, use this to compare, but wait untill i get confirmation from my source that this is the 06 pinout. at a glance, it is completely different then the 2004 / 2005 pinout diagram.
oh damn, i can't attach a pdf to this message, PM me your e-mail address, and i will send it to you at once. [/url]

maybe this will work?

Ok, the skinney on the AFC Neo, piggy-back air fuel controller, installed on my `06 n/a XA running a short-ram intake, DC header, High-flow cat (no resonator), and custom exhaust w/N1 styled muffler.
First, I originally got the Neo after experiencing some very lean fuel settings by the stock ECU. With all that free flowing air in and out of the engine I guess it doesn't take much fuel to get things going. As for fuel economy I was getting roughly 38mpg.
Now with the Neo installed properly things have changed, dramatically. I just needed the A/F mixure richened up a bit in the 4-6k rpm range without the use of a Wide Band Uego, dyno testing, or causing an ECL. I found just upping the mixture percentage between 1-5% was my best bet for increasing power.
The AFC Neo helped me to richen my A/F mixture beyond the lean settings of the stock ECU, which has resulted in much greater power in the high rpm range. Actually I'm quite shocked at how strong the car pulls at 5k rpm, in all gears, with just that small of a change in the mixture. I found that on a small car like the XA, small changes can make a big difference actually a much greater difference then the initial I/H/E setup .
Note; on the new Greddy 1nz-fe 2006 ECU pinout, that the E6-#28 didn't work right for the "Air Flow Sensor", so I switched to the old E6-#24 pin position from earlier pinouts and all sensors checked out fine.

Let us know how it is working after a few days, and again after a few weeks. I'd like to know if the stock ECU begins compensating for the adjustments the AFC-NEO makes.
Also, if you can afford it, and have a local place try and get the car dyno'd with and without the AFC. It would be great to see what kind of gains, if any you get.
Glad to see you got it up and working.

My results, on the rode, have been the ability richen up A/F settings at the 4k-6k rpm range for much more power than what the ECU was generating. Also now when I increase octane or switch from short ram to CAI the power is noticable and consistent with no correction from the ECU.
Once again, the AFC I'm useing is the Apexi Neo with the ECU tripped.
