Getting rid of air is getting rid of air, it doesn't matter if it's 100% of the air or 10% of the air, you will still be changing the volume of air getting into the engine after it has already been metered by the MAF.

 

I have explained that twice already. I speak from personal experience, so take it how you wish. It works, you will run normal, do with this info as you wish. Im not going to convince you otherwise, so im not going to try.

BTW, go check out the newest issue of Import tuner. You will love the basically stock STI in there running a HKS ssqv with just a reflash and still running the MAF.

 

It worked for you, but that doesn't mean it'll work for everyone. As I said earlier, some evo guys run intakes and BOVs without any problems, others do it and they end up with a car that doesn't idle right and is slower than stock.
Import Tuner is hardly a great source, they make claims of gaining 3 hp with just a grounding kit and advocate the use of just intakes on cars like evos and WRXs yet anyone in these communities know that is a bad idea.

 

I love this thread, such a great topic to discuss. Really makes people dig deep into their knowledge of the lancer and give great answers...

 

hks ssqv is pretty loud too manny if your recirculate it

 

Personally, I can't stand loud blow off valves. Sure they sound nice, but they get on my nerves after a while. It is even worse when it is some idiot kid. Do I plan on getting a new blow off valve? Yes? Will I VTA or recirculate? I found a nice BOV from Turbo XS that is a direct bolt on for my car that replaces the POS stock plastic one. Yes, it recirculates. I really don't want to call any undo attention my way.

 

I may have missed it but I didnt see any one explaining why you cant just put the bov before the maf...seems like the logical solution if you want loud

 

You can but then you'd have to send pressurized air through the MAF and I'm not sure if that's a good idea.
OT, Kurt, congrats on the mazdaspeed3, how awesome was it to trade in the lancer for that?

 

It sounds like reason isn't going to hinder you, despite all reason being against you.

Here's the bottom line, prefaced with the fact that I've skipped posts 13-the one prior to this.

The stock ECU doesn't understand what's happening when you vent to atmosphere. The air it's metered will disappear from the system, but the fuel for that determined amount will still be delivered to the combustion chamber. Your car will at best run poorly when you come off the throttle. At worst you will carbon foul plugs frequently and/or cause misfires and stalls.

Your best bet ffor a properly running car is to convert your car to speed density, which essentially requires a standaone ECU.

As someone who has done a lot of research for the Lancer community at relatively great personal expense, and had successes as well as tremendous failures, and as someone who has run a VTA BoV on his Lancer WITH a standalone ECU, let me caution you that you're being stubborn over something that's bound to cause you trouble. Get over the sound and enjoy a car that runs properly.

 

Won't make a difference.

 

This thread is actually pretty stupid and has been posted at least 2 dozen times. Yet people still keep posting them.

 

I may be lacking logic here completely but wouldnt that makes it easier to tune? If its reading your air for you and adding gas to get its mix right wouldnt it run better?

 

Just keep your stock bov, you even admitted that it works fine and better than the aftermarket bovs.

 

I don't think the MAF is designed to be able to read pressurized air. The ECU is also not designed for a turboed car.

 

This is what you get for skipping the post. You make your self look like a dick. I am not arguing that you can or cannot VTA your BOV. I just asked if there was a safe way to do it. I am not being stubborn over anything, becuase I came to a conclusion to not to VTA before you started posting on this thread. So please keep your smart remarks to yourself and accuse someone of being too stubborn about a topic. And if you read carefully you would see that i do not argue over any of these comments that members have posted. Other members have argued but not me.
