Title: What should I change to proper work atmospheric DV Post by: Gabriel on February 05, 2013, 11:45:49 AM Hi guys,
Im using seat leon 1.8T APP, and I wondered... Enyone try to edit ECU and open DV to atmosphere without faults? thanks, Gabriel Title: Re: What should I change to proper work atmospheric DV Post by: prj on February 05, 2013, 12:11:42 PM Not going to work, unless you put MAF on pressure side, and even then it's not going to work very well.
Title: Re: What should I change to proper work atmospheric DV Post by: Gabriel on February 05, 2013, 01:17:23 PM thanks, I was curious is there a way, to open DV...

The need to sound like a chav ::) Title: Re: What should I change to proper work atmospheric DV Post by: Gabriel on February 06, 2013, 04:14:10 AM What problem are you trying to solve that can't be fixed with a normal DV? only sound, nothing else. I heard its possible...I'm only curious :) Title: Re: What should I change to proper work atmospheric DV Post by: prj on February 06, 2013, 06:34:51 AM only sound, nothing else. I heard its possible... I'm only curious :) Surely everything you hear is 100% right. Go to the person you heard it from and let them do it then? Why are you asking here? Title: Re: What should I change to proper work atmospheric DV Post by: Gabriel on February 06, 2013, 06:41:50 AM man... I was only curious.
i'm guessing that if U dont know how to do it - then its imppossible? thanks for the replay Title: Re: What should I change to proper work atmospheric DV Post by: ddillenger on February 06, 2013, 08:30:57 AM The only way to do it is to build a blow through MAF setup so the BOV dumps BEFORE the air is measured. Otherwise you'll run pig rich due to the massive air leak post maf.
Title: Re: What should I change to proper work atmospheric DV Post by: Gabriel on February 06, 2013, 08:40:13 AM exactly...
Can I recalibrate MAF setup of value wich is comming from the DV? Title: Re: What should I change to proper work atmospheric DV Post by: nyet on February 06, 2013, 08:44:04 AM exactly... So you know what blow through is? Quote Can I recalibrate MAF setup of value wich is comming from the DV? OH, wait you don't :( Title: Re: What should I change to proper work atmospheric DV Post by: ddillenger on February 06, 2013, 08:49:53 AM exactly... Can I recalibrate MAF setup of value wich is comming from the DV? Sure. If you could figure out a way to measure the amount of air being lost via the BOV, and then subtract it from the volume of air that entered the system before the maf signal made it to the ecu. (You can't do this.) If you want a BOV, or atmospheric DV, you have ONE choice. BLOWTHROUGH MAF, which measures the air entering the engine after the BOV to take into account the losses when the valve cracks. Title: Re: What should I change to proper work atmospheric DV Post by: Gabriel on February 06, 2013, 09:00:47 AM Any tips to do that?
U mean to open stock airbox? this should get the sound... Title: Re: What should I change to proper work atmospheric DV Post by: ddillenger on February 06, 2013, 09:15:50 AM Did you miss the part in parenthesis?
(YOU CAN'T DO THIS) To run a BOV properly in a draw through application you would have to find a way to measure the air that escapes the BOV and subtract it from the air that entered to provide a corrected figure to the ecu. As there is no way to do this, blowthrough is your only option. Title: Re: What should I change to proper work atmospheric DV Post by: nyet on February 06, 2013, 09:18:34 AM Any tips to do that?

Title: Re: What should I change to proper work atmospheric DV Post by: Gabriel on February 06, 2013, 09:35:52 AM Ok guys.... Im not so clever as You. I just want to learn something :)
I missed that part, yeah... sorry for dum question... Title: Re: What should I change to proper work atmospheric DV Post by: ddillenger on February 06, 2013, 09:40:20 AM What you're asking is tantamount to sacrilege. The only way it would be worse is if you were asking about running mafless.
We take our MAF's pretty serious around here. lol Title: Re: What should I change to proper work atmospheric DV Post by: Gabriel on February 06, 2013, 09:42:46 AM I wasn't going that way (removing MAF)
Thanks for expalining, and sorry for missunderstanding :) Title: Re: What should I change to proper work atmospheric DV Post by: ddillenger on February 06, 2013, 09:45:03 AM No problem. Everyone asks (stupid) questions at first, the test is if you continue to ask them after you should know better and have been here a while. Good luck, stick with a diverter valve.
