HKS SQIV BOV

First of all I'm going on record that I NEVER SAID IT WOULD OR WOULDN'T RUN RICH ON 50/50 BOV SETUP!!!

You all are saying it will!

Again I never said it wouldn't!

All I said was if your so positive that it will (WHICH YOUVE SAID MULTIPLE TIMES) then post PROOF OF A 50/50 SETUP RUNNING RICH!

NOT a regular BOV, which HAS been PROOVEN to run rich.

I never took sides one way or another so don't get that Twista partnas

It's basic engine tuning. it's a side effect of running a VTA on a non blow through MAF car.

Air goes into the intake and gets metered by the MAF. This value is sent to the ECU and tells the car how much fueling is required. When the throttle plate closes, the amount of air being vented out gets remetered by the MAF and causes it to create a rich condition for a short period of time. It doesn't matter whether you vent 100% or 20%, it's going to create a richer condition than if you were to not vent. The ECU tells the car to add more fuel because the MAF senses air but it's really not adding any more air. No air, more fuel is going to create a rich condition. Which is why you need to recirculates it back into the intake tract AFTER the MAF or have the bov placed before the MAF.

Of course, venting 100% would create a more rich condition than 20%. You probably won't have all the backfires and possible sputtering issue by venting less to the atmosphere but will still create a more rich condition than not venting anything at all.

and then you have to deal with the heat soak from the open element like the god awful injen

I'm wondering how this AEM will hold up to heat soak. Once it warms up here, I'll take some datalogs...should I do just a normal traffic light road type of datalog and then hit the highway to see how long it takes to cool down? I mean, stock had it's heat soak for sure when I'd watch those temps fly up while idling in summer. Once you started driving again, it went down...which the AEM did also, but it hasn't gotten hot yet.

Knowing the ambient temps and having datalogs would be great. I like to look and review data.

twist and contort that argument buddy, You are arguing with us after we have told you and showed you venting metered air will run rich, again it doesnt matter if its 100% BOV or 50% BOV. By saying we dont have proof, you are arguing against how maf tuned car works. Rich is rich whether a little or a lot. and did you miss the screenshot I posted from Derek of IMW about why its pointless to even replace the stock bpv with another bpv? That would apply to a 50/50 as well. Here it is again. DONT MESS WITH THE STOCK BPV.

So how do you go about data logging for rich conditions. For example to create charts like the one posted for the Boomba valve . How do you do it? Software? CPU? What do you need to do..?

He says AFR is the same...has a vid showing it. So maybe this doesnt effect the car like we thought?
