safc uninstall

[98GSXboosted]

Hey i'm selling my safc. I want to uninstall it but I wasn't the one who installed it in the first place. is it hard to uninstall? Under the center console there is a black harness that it plugs into, do i unplug it from there or from the ecu itself? will my car run normal when i take it off? or will i have to do something to it before i take it out?

I just took off a vafc this weekend and its not that hard. You have something like this. SAFC ---> harness ----> ecu. This is the harness that you see. You need to find the connections going to the ecu. Some will be tapped into and some will be cut. The ones that were spliced you should just disconnect and wrap where it was spliced with electrical tape. The ones that were cut are the ones you need to reconnect. John

There is one wire that is cut, you are going to have to re-connect it to make your car run right again.

The question is what did you have done to your car that you needed an AFC? If you have bigger injectors your car wont run right if you pull it out. In that fact you will have to pull the injectors out and turn down the boost in order to pull it out. brian

also sometimes removing and safc will make the car run weird since the ecu has to relearn everything that the safc changed..

No it won't. The short-term fuel trims will compensate for whatever the S-AFC eventually changed in the long-term fuel trims almost instantaneously.

PS its the airflow signal wire. pin 90 shown here: http://www.vfaq.com/mods/ecu-harness-2G.html

I believe it is the orange wire. Look up VFAQ to make sure. Also, the level of difficulty will be with how the SAFC was wired on there in the first place. If the original installer cut every single wire and did a 3-way solder, then it will be a pain to do. The second way I can think of is by splitting the insulator and just soldering the wire on there (no cutting). Since I've ran into this problem before, When I did my installation, I split the insulator and soldered a wire + female connector to the ECU. Then I soldered the male connector to the harness of the SAFC. Now I have a plug and play (so I can remove it anytime I want).

I'm going to have to remember that in the future for you. John

From vfaq.

I used it and it is much simpler than using the regular instructions w/o pics.
