I made the decision before I read all of this lol. What would be the possible outcomes of running with the bov and tune ?

 

You need to relocate if you aren't going to recirculate or it's not gonna run well.

 

And you've never heard of a way around this?

 

what dont you understand? there is NO WAY TO TUNE AROUND THIS. end of story. You literally ignored everything i just said. Theres 2 ways to physically go around it in my previous post. Your "learning" right? then read what i said and read it again so you know. Those are the only 2 ways to run a blow off valve.

you are venting metered air that your computer has already scaled... when it blows off your computer is like where did all the air i just read go? and it dumps fuel. it doesnt matter what your "tuner" says or anything. you cannot change the fact of whats physically going on.

if you wanna vta you have someone weld a maf flange to your cold side pipe and extend your wired and recalibrate your maf and then tune. if you want to recirculate you have someone weld a bung on the intake and run a hose from the bov port to the intake and no additional tuning is required.

 

**** it I'll just get the recirculating valve from them.

 

Who is tuning you?!

 

This guy is probably one of the best if not the best tuner and most knowledgeable guy on our platform. Take what he says as the only thing you need to know. He's the eminem of our cars. Legend

 

M n M autosports

 

Get an e tune. He's charging too much and probably doesn't have experience on the platform

 

Dude... Just listen next time lol. It'll save you time and money.

 

the hahn valve can be recirculated. it has a port on it. all you do is have someone weld a bung onto the intake and then run a hose from the hahn valve to the bung on the intake valve and your done.

thanks for the kind words eveyrone

 

Now you are on the right track. Op we are just trying to help so don't get upset. What works on some platforms doesn't work on others. You have to go with what does and listen to those who have experience working on these cars so you don't end up with a sad car that doesn't run right and cost you a lot of money.
I would also highly encourage you to check around on the tune as its the most important part. A lot of experienced tuners who do well on most other cars, can struggle on an ecotec. You want the most safe power you can out of the car and it to run smooth without knock and those who have experience tuning these cars are your best bet. Just some more advice.

 

[quote=Omiotek]Let me explain it to you like this....... point blank.


If your venting to atmosphere you NEED a maf relocate. End of story. The car spikes rich because metered air leaves the system. There is no tuning around this because you cannot change what is happening.

Now if you are using a recirculating blow off valve you do not need a maf relocate because the system always stays closed and the metered air remains in the system.

Theres no debating this topic.

Ive beaten this topic to death. I have 12 legal years of automotive experience and ive been wrenching since i was 10. I have a total of nearly 7 years with ecotec based platforms Ive been on a top fuel team, nitro powered nostalgia drag teams, i road race and have a drag car and i currently build chassis for a living. Just to give you an idea of a little bit of my background.[/
Have you ever heard of any tuners in Ontario? I posted a thread in the tuning section but thought I'd ask anyways since you know your ****

 

Spend some time learning about the tuning process. It'll help you in the long run.

These questions have been answered countless times.

 

I'm looking for a good tuner dude. I know what I have to do now depending on what output I want from the tune

 

Do you have hp tuners?

 

if you have hp tuners you can get tuned by a couple guys on here willing to help you. I know KMO43 is in canada but im not sure exactly where, he is one hell of a tuner and would probably be willing to help you. i told you in my first post on this thread you would need a maf relocate even before you ordered you stuff. so me and omniotek both told you not to do it and you still did. 95% of the guys on this forum are all very very knowledgeable. the ones that you see who have been here the longest, take all the advice you can get because we all know about the cars. this isnt facebook where you will be getting a bunch of young punk kids trying to sound smart and answering your questions.

 

Just gonna throw my 2 cents here.

I ran a VTA BOV for 2+ years no problems. It only goes rich when you shift. However, I swapped to a lower spring and it started having issues. It started throwing p0101 and killing my car.

Then I ran a MAF relocate and all was well. it really is pretty simple to relocate the MAF.

 

You ran the forge bpv and yes term worked a little magic, and your car still went stupid rich between shifts the bov he was talking about getting would of been worse.

 

I thought buddies a bad ass tuner bro or mane or whatever you like to go by

 

We don't have to hold this guy's hand through every step.

There is tons of material on tuning and the process. If he can't figure it out he's probably best off not tuning his car.

Our cars have officially fell into high school kid budgets and threads like this will start to flood the forums. 20 threads on the same subject just starts to clutter things.

 

I don't know who to trust now. I spoke to Hahn and they said they've tuned a lot of cobalts with their regular bov with no maf relocate and have had great results. Not doubting your knowledge but just saying

 

Wtf r u talking about. I worked my ass off to own my cobalt and I'm just looking for people who have experience working on them. I don't give a **** what it takes to make it right even if I have to ask question upon question.

 

Yeah that's what the tuner I found is gonna use

 

Naw I think I ordered it a couple days before I checked the thread for responses lol. Always learning **** the hard way I guess. I think I'm on the right track now, thanks for putting up with my bullshit
