venting bov

[gunner52]

well ive been looking for a cheap easy way to vent my bov mainly just for the sound and i havent been able to find much so if theres already a thread some where please send me a link and we can delete this. but heres what ive come up with for options 1. is get a sfac or dsm link ect.. and set it up to vent 2. get a maft and gm maf and set that up to vent 3. relocate my maf after the bov but this option requires some adapters and a buncha silicone cuoplers which is still ###### gonna cost 100 or better so i might as well just go with a maft set up unless theres some thin cheaper or easier that i can do thanksfor any help or redirecting me to the info i need

In order to vent correctly (the computer sees the actual amount of air going into the engine) you need to run a blowthrough setup, or speed density.

1. SAFC and DSMLink can't do blowthough by themselves. You would need a MAF-T to do a blowthrough. It's just speculation, but some people think that the next version of DSMLink will be able to do a true speed density, or have plug and play capability with the GM MAF.

2. If you get a MAF (and the MAFT you need to run it) then you wouldn't really need a SAFC. The MAFT has tuning capabilities. You would still need a logger though. I think the newest version of the MAFT can do speed density, so you might not even need the MAF sensor itself.

3. The stock air sensor can't be run in a blowthrough setup. That's why people convert to the GM MAF.

The cheapest route for a street car would be MAF, MAFT, and a pocket logger. Maybe a chip to allow bigger injectors.

The next step up from that would be DSMLink, with a MAFT and MAF (you would just use the MAFT to convert the signal, not tune). Plus you would need a laptop or Palm to run Link.

Then the last step is AEM EMS in speed density, which has the best tuning capabilities, but the steepest learning curve.

I'm going to be running DSMLink on a palm pilot, with a recirculated BOV. It's not that important to me. If the next version of Link really does have plug/play capabilities with the GM MAF, I might switch over to a blowthrough, and then vent.

Hope that was helpful.
