running a vafc on a automatic
anyone have experience running on a vafc on a automatic car. i got the f20b running off the stock f22b1 ecu but think it could be better, nobody makes anything for tuning on a auto, so i was thinking go vafc and some 310cc injectors. anyone ever try this on their auto?

the vafc is good on an auto, however it helps to have mods to help tune

V-TEC Air Flow Converter. I dont want to say anything more in fear that it'll be wrong. But im sure its just a controller for air flow etc. I'll let the more knowledge worthy chime in...

Zero its Vtec Air Fuel controller. You can change ur vtec engagement point and monitor your a/f ratio and modify it to a certain extent.

a VAFC is a pointless mod IMO. I have 1 on my Lude. I messed around with the settings, couldn't gauge any significant increase. Only MPG loss. Lowering VTEC engagement is stupid too, it really likes the stock setting of 5200...give or take a few 100 rpm. Once my exhaust leak is fixed, I will try to get a dyno tune to lean out engine a bit cause h22 run really rich. If it nets a power increase, so be it.

The price of the vafc and the tune was cheaper than the price of all the bolt ons I had, and I received the same amount of whp gains from it. Seemed like a great investment on my end a few years back.
I showed the dyno on it a few years back on the gains of my bolt ons before a tune, and after the tune.
To get 12-13whp out of a tune with the vafc is more than you'll get out of any other mod not including boost/n2o. For the price range, it was well worth it. And I'm only referring to these engines. I'm very aware of the benefits of other mods for other engines. I'm strickly referring to our J series.

If you look around you can find a VAFC for 150-200. I got mine for 170 shipped to my door brand new. When i got it, the box on it said the price was $350 lol. But yea, i agree with cocoa. you can get some significant gains with the right mods and playing around with a VAFC.
Dicorp, my buddy has an H22 civic and a vafc and he changed is vtec engagement point to 4500 and tweaked a couple things here and there, worked out to his benefit. I guess different cars have a different reaction unless you get a professional to tweak it for you.

That was the point I'm trying to make, you can pull more horses out of a modded engine with a tune

Once again this thread turned into a bunch of knowit all "OGs" arguing over a noob question.

lol idk if i even count as an OG, i was just giving perspective on different experiences. Noone is necessarily right or wrong, just stating what I've seen.

And just because we have experience with something doesn't make us knowitalls. The point that cocoa and I were trying to make was against your statement that it doesn't serve a purpose. What we were trying to tell him, is that it will benefit with the right bolt-ons and a tune. Not without them.

i still think it's kinda inbetween. most people dont even bother with bolt ons. and the rest just go for more advanced shit like cams, valve train etc. in which case you'd need somethin more serious like hondata or crome.

anyways, ill get my car tuned with the VAFC and see if it changes anything.

I win
i havent gotten it fully tuned yet, the only thing i've done is raise the vtec to 4600 instead of the 35 and doing that little tweak made it perform alot better. Once i have the time im going to take it to get fully tuned. imo, its not a worthless mod but probably one of the best for our cars

i was moreso worryed about it messing with shift ponits or auto trans shiz.
i can't go hondata or aem or even backdate to obd-1 on a auto, so my option was vafc2 or aem fic, never dealt wih the aem fic so i was going to go vafc2 for some tunabilty on a auto.
i'll wire it up but i'm taking it in to a shop for dyno tune with wideband 02, i got a few thing i want to install to get the most out of the tune(injectors,adj fpr, hi flow fuel rail)before tune.
i appreicate everyone's info on their experiences, +or-.
