What it is is a resisitor that advances the timing on the engine about 2 degrees, there's a post somewhere on the site but it does make about 5-7 hp increase, find the post on the site though, it tells you what resisitor to use so u don't have to pay on ebay

All it does is throw a resistor inline with your intake air temperature sensor so your car thinks it's sucking in colder air, thereby dumping in more fuel and advancing the spark a bit. You can do this with some simple tools, another male IAT sensor and a $0.50 part from radio-shack.
On another note, I'm working on building a table of what the resistance across the IAT is at various temperatures so I can select the right resistor to make my car belive it's always 20 degrees colder outside... Just gotta make sure the resistance dosen't increase logrhythmicly as the temp drops and I'll be fine....
If anyone else is doing the same thing here's all I've gotten so far:
If surface temp = 78.6 F, it will read about 1500 ohms
If surface temp = 98.6 F, it will read about 1100 ohms
When I get it done I'll post my results for any/all who are interested.
Oh, and to the disbelievers, this mod will have less of an effect on you if you live in a very humid area, the humidity wreaks havoc with the intake charge stratification and therefore you use fuel less efficiently.

Rep Power: 0 all this crap does is play with your mind! Its kinda like....if u put this on, u will automotically think your got faster cuz u have done somethin to it....
but the reall truth...it WILL NOT do jack!! i gotta friend that used to have one and he tryied to dyno it...no gains...

Rep Power: 0 It's really pretty simple... Add more fuel, advance the timing a bit, you'll make more power at the loss of MPG...
Oh, and on further research, most of these little kits put the resistor in parallel with the sensor... That will actually -hurt- performance on a Honda because our IAT sensors work backwards from american ones. If you buy one of these kits, the engine will constantly think it's hotter outside and you can potentially wipe your engine from running over-lean when it gets cold.
Before you discredit it, at least figure out what it's trying to do and then how you can make it work.
VAFC-II adds more fuel and bumps ignition timing and many folks run it. What is everyone's problem with this whole idea?
