i have heard mixed things about them and i was wondering if it is worth the purchase.

 

what kind of mixed things did you hear?

 

Its worth it if you have a motor with mods. Its one of the easiest ways to fine tuned your motor because the mods will change the way it runs(meaning how much fuel and air it requires). I definitely recomend one if you have a b-series and are looking to get the most out of the motor. Plus it looks cool at night.

 

Great for taking away fuel. Shitty for adding. (All it does is change map sensor voltages/reading.) No ignition support.

Hondata is a much better choice, or uberdata for that matter. How much does a VAFC go for these days? I cant imagine its much cheaper than $225 (brand new of course) which of course is the going rate for the entry level Hondata s100.

 

yea **** a vafc is going for like 330 thats the cheapest one i have seen but hondata seems like the way to go

 

VAFC's go for 150 to 175 all day long used and for and entire Hondata setup, its much more. Sure Hondata's great but if your not pushing over 210+, why bother its really not going to do anything more for you.

 

I disagree, stock honda engines run notoriously rich up top (covering up a multitude of sins) and overly retarded. Igntion advance and a little leaning out (which the VAFC can only do the latter of) really opens up the power.

 

waste of money bc im guessing you dont have enough mods for it to make a difference or else you would've listened them

and ummm you're a ricer but if thats your thing drop a couple hundred bucks so it will "look cool"

 

i use the vafc in my race car along with a hondata s100....... its mainly used as data acqusition for throttle position, rpm's, and most importantly, vacuum. i leave all the settings at 0 and i dont have it hooked up to where you can change the vtec crossover point. ive used a vafc in my street car and i was pretty happy with it. just make sure you throw it on the dyno and get it tuned. thats really the only way to make any difference with it. hope this helps. peace

 

I guess that was a ricer comment, but no I'm not one. I bought a vafc for the performance purpose, and it was real cheap cause it was used. My car is very clean, just in case you were wondering.

 

I got a vafc on my mostly stock civic si, with out dyno tuning I dropped the vtec engagement 200 rpm to 5400, richened fuel 5% after vtec and that **** pulls to red in every gear.

 

Sorry to bring this thread back from the dead but..

I was looking around for some cams for my B18, im planning on putting an ITB for autox and some internal work.

I came across crowers stage 2 Road/Rally Street/Strip ( http://www.crower.com/cat/impo...shtml ) and i liked the features

but it also says a Vtec Controller is recommended. Would it be better than a hondata computer or would it be better to have both?.. im not really familiar with vtec controllers and im trying to do some research
Thanks

 

Stay away from the Vtec controller, invest in quality engine management.

so an engine management is a step up from a vtec controller? and by getting a quality engine management i could fully tune my engine with only the EM system?

A VTEC controller is a form of engine management, although it's a rather weak one. Basically it works well for bolt-ons, but anything more requires engine management of a different degree.

Yes. The natural exceptions will be cam timing and fuel pressure. But the fuel and ignition maps will be fully programmable by the user/tuner.

 

Sounds good, Thanks for the help... any specific brand w/ a quality EM system? I can only think of AEM right now

 

Hondata.
