S or V afc?
 
I only see the VTEC control as the difference? I have D16Y7 so I dont have VTEC but thats not to say some day I wont. Should I get the V-AFC or the S-AFC? I am currently putting together my buy list. Thanks in advance.

GO V, same price for an added feature

If you plan on VTEC eventually, then get the V-AFC.
If you never plan to get VTEC, get an S-AFC.. they're both almost exactly the same. The S-AFC has an extra input that you can monitor voltage.. O2 is what it is normally used for.

Thanks for the response. So I can disable the VTEC function? If so I will get the V-AFC. It says its good for VTEC/iVTEC ecus. I dont have VTEC, it will still work? Do I just disable the high cam setting?

There is no "disabling". Just don't connect the wiring for it.

..and there is no low and high cam setting. Only narrow and wide throttle. Tune both, your TPS percetn is the changeover.

Actually, yes there is a low and high setting, as well as narrow and wide. There are four total to set on the vafc. Just set the high for whatever you would set it for out of vtec. You might have to adjust a few other things too, since the low side normally doesn't go all the way to red line. I'm not sure if it would automatically use the vtec settings for the rest of the way to red line or not. Ask someone who has done it.

Oooooooo ya.

D'er. [me=TurboEF9]stamps "I'm a dumbass on his forehead".[/me]

Yes, there is low, and high settings on both (having actually walked out to my car to look at his V-AFC). I had forgotten. d16tuner is 100% correct.

I know narrow and wide is done based on TPS (someone correct me if I'm wrong here..), however, what is the indicator that switches between the low and high settings in narrow and wide?

It should be using the high settings whenever the ecu engages vtec and the pretty red light comes on. That is why I'm not sure would happen on a car without vtec - since it won't get the signal. I'll bet it will just continue to use the highest fuel setting on the lvt map. Either that, or I expect it would fall on it's face when all that fuel get's dumped. Surely someone has tried this and can comment...

Well, I've run it with a turbo without he VTEC wired hooked up (probably about a month or so) and had no issues. Hrm..

I also never noticed a red light come on when I was in VTEC.. sheesh.. $300, you'd think I pay attention to the little bastard somemore when I was using it.
