hey everyone i usually post in the eg+ forum but today im in need of the help of you integra guys. i bought a vafc from a friend and im looking to install into my 98 OBDII gsr swapped civic im not really looking to tune it at this point as i have only bolt ons. since i bought it used i found the booklet at apex.com so dont send me there for help. after aprox 30 mins of searching for my answers i come to you guys what im lookin for is a pinout diagram or listing of what wires i will need to tap into. in addition i would like to know if there is anything i need to know while installing, like are there settings i need to know about, im really just looking to get it installed for now, but if there are settings i must set or change in order to get it running correctly i would like to know before i start. besides wiring is this a job a noob can do?

cliff notes : what do i need to know to install vafc in a gsr swapped civic (because i have never done it before)

TIA

 

when u install everything, just turn the key to the on position, dont satrt anything. on the main menu on the AFC, go to settings. In the settings menu, choose the throttle type with the arrow pointing up, the part where it says IN OUT, put both to 06, choose the sensor type as Pressure. after this is done, set all the high and low throttle settings to 0% (the previous settings that ur friend had on the VAFC will be saved, so u need to set them all to 0%)

I used the wiring diagram that is on the APEXI website to hook up my AFC. It was very simple. just follow the diagram on there. http://www.apexi-usa.com go to the documenation link and scroll down to the VAFC to get the diagram

use the OBDII diagram

 

thanks im not sure what actually happened but it kept goin back to 6 cyl for some reason i did the initializing again and for some reason it worked i did it exactly like you said, i thought i did it that way the first time, but either way it works now and thanks again for you

 

no probelm. i almost forgot that u had to select how many cylinders u have. good to hear it's work n good now

 

the wiring is easy.

since you've already discarded the official instructions on the APEXi site i don't know what to tell you. maybe you should just pay someone else to do an hour's job. *shrug*

 

well it sounds like he has already wired it up.

 

do you need a dyno or anything to tune these for your engine? like if i get one, is there a way to figure out what air/fuel and what not without a dyno?

It's best to tune it with dyno, but you can get away with using a wideband o2 and and a/f gauge......

btw... I gained whp thoughout my pwrband with vafc tuning even +18 at one point..
