is it nessasary for a car with full exhaust system and air filter??

You'll have to define necessary

But yeah you can gain a handy amount of kw's if you tune your car to make use of the improved air flow characteristics. In fact a VAFC on a stock car can add 5-10kW pretty easily because most if not all cars are tuned rich from the factory (for reliability).

And it just so happens I have one for sale if you're interested

dont mean to hi-jack but does VAFC monitor fuel consumption etc?
Cuz i dunno about u tegra ppl but EG civic fuel meter is pretty off..
I like to monitor it to see any changes in my car and see if its driving normally etc...

Nope. VAFC doesn't monitor fuel consumption. It monitors

-Revs
-Throttle Position
-Intake air flow pressure (from a sensor in your intake)
-air/fuel ratio correction (% that you set)
-VTEC from the ecu
-VTEC from the VAFC,

I think that's it... But most importantly it looks cool

yeah agreed vtir22... it "helps" if you have some mods before you waste money to tune one in... not going to notice any serious performance gains form a v-afc alone...

i like to think of it as a smoothing tool... after you have light mods on the car...

Hey guys, was giving the vafc 2 some thought but was comparing it to a sard or aem fuel pressure regulator and was wondering if the Fuel press reg is better than the vafc 2

?

**type one** · 17-09-2004 11:26 AM

they have different uses...

used in conjunction they can help a high hp n/a car... but again sard fpr not for mildly modified car... waste of time.

Yep, I'd hardly think you'd need a fuel pressure regulator unless you're pushing much higher numbers than stock. VAFC you could consider a 'fine tuning' mod.

The Honda ECU will 'relearn' and over ride the vafc in about 2 weeks after having it tuned. Unless you wish to tune it every month - stay away from it

Dont get an FPR unless you drive a Turbo car imo...or are silly like me

Are you sure about this?
Why would Apexi create a product specifically designed for vtec machines (hence the V in VAFC), althought it can be used for Mivec also, that would be useful for only a couple weeks after tuning?
And why would people continue to buy this product and apexi release a 2nd version of it, if this was the case..

Im not saying your wrong, i just find it hard to beleive that that is the case
