VAFC Questions
For the guys that Have a VAFC or have installed one please help me answer a couple questions. I've searched the forum for the last two days, alot of the posts are very old. Vetc.Air.Flow.Controller sounds straight forward but i still need to fully undestand this.
1. What the sole purpose of this unit is?
2. Best unit? price? and where to buy?
3.Install difficulity? Common Problems? Gains/Losses?
-Thanks for the help!

I bought mine for $100 in the for sale forums. That's undoubtely the best place to find them. Unless you want to deal with the wiring you'll also need a plug and play harness that's something like $150. I made a diagram for the wiring that should help if you want to try and tackle it without the pnp. On top of that, it's useless unless you get it tuned. If you have a wideband O2 sensor ($200-250 I think)you can get a reasonably decent tune on your own, otherwise you'll need someone to tune it. I'd guess that'll run $300+.

Problems are going to relate to install issues. Either a bad connection or connected to the wrong wire. You'll likely throw a CEL. Find the problem, fix it. A lot of people talk bad about the VAFC, but I love it for what it is.
Gains are going to depend on the year of your car and how good your tune is. '00 and '01 cars pick up a good bit more than other years. I can't attest to my specific numbers as I had other modifications between my 2 dynos. It was evident that I picked up considerable power from the VAFC by lowering vtec to 5200, not sure if you'd seen the same gains if you're NA.
Hope that helps, if you have any other questions don't hesitate to ask. Good luck.
