S-AFC II install for 1st gen OBDI altima

[Importroller]

does anyone know where I can find this info? I tried google, and came up short, tried NICO, and Nada results.

yeah i was wanting to do the same thing to my obdII

For the OBDI Altima, Look at Diagram N-1 on the following link (page 4):

For the OBDII Altima, look at Diagram N-3b on the following link (page 33):

http://www.apexi-usa.com/produ...g.pdf

Both use HW5 MAF sensor signals.

edit: These links are backwards

i already have a pinout diagram of my ECU. I guess the info in the box will tell me which wires to splice into. Ill wait and see what shows up in the box. should be here tomorrow

I think you have them reversed. the first link shows the OBDII ecu. and the second link, that should show the OBDI setup, isnt working for me. and the instruction book, I got, doesnt give any specific detail about ANY KA24DE setup. So, Im not sure which wires to splice into

Sorry about that, you are right, I do have the links backwards.

But anyway, it should be diagram (N-3b). If you look on that link (the 4 page one), look at Nissan in the chart. It shows the S13 with the KA24E and KA24DE both as diagram N-3b. Because the Altima uses the same engine, the ECU pinout *SHOULD* be the same. The S14 with the KA24DE is listed as diagram N-1 (from the USA suplement), just as the U13 with the KA24DE is.

Make sure you have the correct wires off of the SAFC connected. I think there are two grounds (brown and black?) and they must be connected in a certain order. Also, make sure your MAF signal is hooked up correctly. Is the SAFC even coming on? If not, then your power wire is not hooked up correctly. Find out which SAFC readings are messed up, then double check the diagram.

i just got it today, I havent even started the install yet, I was doing a mental install, and making sure i use the correct connections. I have to go pick up some stuff tomorrow for the install over the weekend if i have time. but, looks like Once i get an extension harness (dont wanna cut the main, since the extension didnt come with it), I should be able to have it installed within an hour

another quick question, do we run on a Karman type frequency Air flow or a hot wire type?

[Importroller]

ok, so its a hotwire then

new question. i did the install, and everything seems to be working. but for some reason, when i go to adjust the Hi lo throttle adjustment for the air mixture, it shows "OMIT" on the screen, and wont let me change it

[EZcheese15]

Not sure, check out your hi throttle percentage setting. I suppose if it was set at either 0 or 100% then it would omit either hi or lo settings.

[Importroller]

i figured it out. I guess i must have at some point pressed and held the toggle button to the right too long, and that set it to an Omit mode. when i did that again, i was able to adjust. Now, its time to hit the dyno next week

Are you installing this on your 2007 3.5 or a different Altima?
