Yeah, I just installed mine. No cel or anything. You just use the wire diagram that Carbonfly posted in tech. Works perfectly, well with tuning of course.
Gearbox, Can one of you guys that successfully installed the VAFC2 post some pictures of the wire connections to the ECU harness ? If you guys recalled, there is a DIY on the Apexi RSM "http://www.7thgencivic.com/forums/showthread.php?p=2042142", it seems the ECU wire you guys use for the Pressure Signal is used as the Speed signal wire in the RSM install. Can anyone of you VAFCII experts clarify this ? Also is there any total cutting of the ECU harness wire when installing the VAFCII or are the wires only tapped ? Thanks.

I know what you mean I put one in my ex's (gf at the time) rsx-s and had it dyno tunned....It was sweet when it would kick in expc with 191 whp it deff would put u in ur seat well when i would drive lol she wasnt that good
Anyone can post pictures of the wiring diagram instructions provided with your Apexi VAFCII or the relevant pages needed. I only have the Jap version over here in my country which I do not understand. Thanks.

and just a note. You are soldering to the wire, not directly to the ecu.

if i had a shop do it all do you think it would be done right and with no CEL and have them set the vtec at 5200rpm's,O one more thing does anyone here have an auto and have the vafc 2 lnstalled on there car.

I have an auto with vafcII. It doesn't work on the newer ecus. I tried turning up the fuel, and it corrected itself in a few days back to stock.
And no, a shop will most likely fail the install. There are more wires that are not in the apexi diagram. We have all the info you need in the sticky thread.

so you are saying that it will not work with the auto ecu,and do you think it will be a good infestmint for me.

I'm not sure exactly, but it seemed like it wasn't doing anything. Only way to tell for sure is get it dyno tuned and go back there a year later to see what happened.

Well it does let you monitor engine settings like rpm, voltage, throttle, etc. I wouldn't get it if you only have a few boltons. Might give 5whp if you're lucky when tuning it.
