SOOOO I would like to know if a SAFC can fix the stalling problem on my SR20det that is runnign a VTA BOV. Or does a SAFC only work on a pre determined map and can’t be used to control spikes or drops in air intake in real time?? Or has anyone been able to correct this w/o switching MAF’s or going back to re-circ or re-prog the ECU?? THanks, Chris ---

I doubt an SAFC will fix your problem, its is more for fine tuning your A/F stuff at certain RPM. Your problem is more to do with too much air being lost out the BOV. If i were you i would just go with re-circ. Just sounds like that BOV is just letting out so much air that you just go super rich when you let off the gas after boosting. ---

tighten your bov. Mine runs fine with a open to atomsphere bov. It is kind of tight tho, you can hear a little surge at like 1 psi. ---

You can mess with te DECEL function to fix the problem. It seems to work on a good % of guys. ---

switch to a less ricey BOV to prevent all your air from being vented and the car literally “flooding”. or buy a HKS EIDS to prevent this from happening [http://cgi.ebay.com/ebaymotors/HKS-EIDS-H1-Electronic-Idle-Stabilizer-Nissan-SR20DET\_W0QQcmdZViewItemQQcategoryZ33598QQitemZ8043480286QQrdZ1QQsspagenameZWDVW](http://cgi.ebay.com/ebaymotors/HKS-EIDS-H1-Electronic-Idle-Stabilizer-Nissan-SR20DET_W0QQcmdZViewItemQQcategoryZ33598QQitemZ8043480286QQrdZ1QQsspagenameZWDVW) ![http://www.jappartsspecialist.com/3648%20EIDS%20nissan%20H1%20a.JPG](http://www.jappartsspecialist.com/3648%20EIDS%20nissan%20H1%20a.JPG) ---

has anyone figured out how to set the Deceleration Air (DEC AIR) function on the S-AFC 2? it’s supposed to lean the mixture out off throttle to prevent overly rich conditions with open atmosphere BOVs. ---

Well my BOV isn’t “ricey” at all. It does exactly what a BOV is intended to do but every now and then I’m still stalling if I’m not heel toeing to a stop. That HKS EIDS would be great, but a little pricey to fix my problem. I was asking if the AFC can fix it as at least (well I think at least) it can do more then the EIDS. CHris ---
