can you use emanage & SAFC together

[cvex]

i would like to know if this is possible ?reason is to get rid of the stalling w/vented bov through air decelaration mode.

Why would you want a piggyback on a piggy back? The best way to run an open atmosphere BOV is through a MAP sensor. The MAF doesnt work so well for such an application.

Id go with the JWT, S-AFC, S-AFC II, e-manage combo. \

just kidding. bad idea...just....bad idea

I cant get the e-manage anti-stall to work either. I just leaned the crap out of my idle and it's JUST enough to keep it from stalling. (I also have a very high idle set)

you can run the MAF before the TB and after the BOV, so that the air being released is never read by the MAF

thats not a half bad idea....

any more input on this?

why dont more turbo'd vehicles run this setup?

Some MAFs don’t like pressurized air, but I don’t think it’s a problem with Nissan/Infiniti mafs

I have seen a 2 gen Altima boosted this way, and it works very well.

Hot wire MAF's should not have a problem being run in a blow-through set-up, with the exception if the MAF is not designed to hold pressure.

Flap foor, and plunger type MAF's measure velocity, but does not account for density or temperature and would not work.

Also be aware that hot-wire MAF's are calibrated for ambient temperatures. Accuracy will be lost at the higher temps even after the intercooler. You will most certainly have to re-calibrate the ECU to make the hot temps translate back to what the MAF would read before the turbo.

That’s why we have an AIT (Air Intake Temperature) sensor, plug it in after the intercooler and everything should be fine.

A hot-wire MAF automatically picks up on density changes. Since the amount o voltage needed to keep the wire at a specific temperature is directly related to the number of molecules of air passing over it, no calibration is needed. So long as the air running through the MAF is not as hot as the hot-wire itself. Adn I seriously doubt anyone is running enough boost for this to be an issue.

True. I did know that, I was just under the impression that the swing out of the normal temperature range would push the MAF towards one end of the voltage range potentially causing it to run up against one of the preset limits. Hmm, ok, I'll try to be more clear. Its not the hot wire, but the voltage scalar that would be out of range. Or have I just completely lost my mind? Which of course, wouldn't be the first time.
