S-afc ?

[AWD Lox]

I am soon to be installing an S-afc and a friend told me tonight that I could vent my BOV to the atmosphere with the s-afc installed. He said I have to use the deceleration air flow corrections settings for that to work. Does anyone have any tips on how I can go about doing something like this? Thanks

AS far as i know bro, the only way you can "correctly" vent is to go with a blow-through setup such as a GM MAF... SAFC settings or not, your stock maf sensor is still taking into account the air you are blowing off into the atmosphere causing it to run rich in between shifts because it is adding enough fuel for the amount of air which is supposed to be there. Since that is not the actual amount of air, the computer overcompensates thinking there is more air than in reality and adds more fuel. The search feature is very helpful on topics like this

hmm....i can see this thread getting ugly pretty quick

Thanks for the help. This person told me that this feature works by pulling the added fuel you speak of. I am not new to MAF tuning, my supercharged focus was running a MAF setup, and I understand how the meter reads, i was just trying to figure out if it could be "tuned" out with the S-afc.

On the search feature....It sucks on this forum, I have spent about 2 hours since I started posting up here searching for stuff, and the search engine never locates what I am looking for,even when I used the advanced feature...I just look at it and go so thats why I just start the new threads I am intersted in. Thanks for helping the newb...

The 3S guys seem to believe that the dec-air only works on hotwire MAF setups, so on the Karman system it may not work well.

Feel free to try it, though! If you're going to vent, you may want to put a filter on the BOV so that when/if it leaks at idle/vacuum, you're not pulling in unfiltered air into your engine.

Well my focus was no turd..its put down 208hp and 180 ftlbs of tq on 8lbs of boost. Thats probably more than my DSM will put down in its first dyno run..

Thanks for the help guys. I think I will stick with not venting into the atmosphere...

my safc instructions say decel function is only for hotwire type mafs not karman.
