The stock turbo dynamics is way too aggressive for an ewg. It's something like -7 - 5 - 3 - 1 0 +1 +3 +5 +7 It should be something like -1 - 0.78 - 0.56 - 0.32 0 +0.32 +0.56 +0.78 +1 That way the ecu is using smaller percentage increments to control the boost. This is how you get rid of that flutter. I'm posting from my phone so I hope that shows up properly and makes sense

Makes perfect sense though. I can't wait to see the video, provided you find it later. I am going to run a hybrid setup for more reasons than just the flutter, but it'd still be pretty neato to see an EBCS + EWG with no flutter. |

If you turn this up loud enough you can hear the EWG in the background. Even with the crappy sound you can hear that theres no flutter.
I wish I had a better video. I'm really suprised it's not louder in the video, but I dont even have any idea which camera phone it's from at this point. It's from a few years back. |

You can hear it kick in faintly at 1.5 seconds. That is literally the only video I've seen of an EWG + EBCS combo not fluttering. Mind = friggin blown

You should be able to slam that thing up to target boost and hold it rock steady. When I switched over to the Hybrid method, I only picked up maybe 150-200 rpms of spool if even that. Most logs you couldnt even tell a difference depending on where I started the log at. I sold the MBC because I didnt see the benefit to the hybrid system with an external wastegate. It's already solid enough. Theres not enough gain for the complexity of the system in my opinion. |

A MBC will not flutter. It is a spring loaded ball that lifts depending on how much pressure it sees. |

Some good info here. I myself was contemplating going EWG as well in the spring. I have an ebcs.

I understand it's sending pulses to the wastegate, but it's doing it extremely fast. You shouldnt be able to hear it I dont hear any flutter in this video either, although like you said, most of the videos on youtube you can hear it pretty audibly. Would the quality of the solenoid have anything to do with how fast it's pulsing, or would that be completely controlled by the ECU? |

You don't hear the flutter in that video?
Where in Iowa are you located? |

The second video however I feel there is the usual amount of EWG EBCS flutter. I can hear it pretty clear. |

I have to agree with you on that. The second video does have flutter, but it's so minimal compared to most of the EBCS + EWG videos out there. It actually sounds pretty bearable

I dont hear any flutter in that video. Maybe I'm going deaf? My neighbors probably think so after I watched that video like 20 times loud as **** lol
I guess this is what I think of when you say flutter. Obviously this is an extreme case. ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch-ch |

Holy hell, that guy needs a new tuner. I'd never drive my car if it sounded like that. |

Yes that flutter is extreme. That car moves right along though |

STATUS UPDATE:
I FINALLY got my ewg hybrid setup installed. Still need to fine tune it, but it's pretty much done. I will post a video of the before/after sounds as soon as I'm done filming/splicing the two clips together! EDIT: Here's the sound clip. I really need to get a new recording device to really capture how beastly the EWG sounds. This is running off the hybrid setup mentioned in this thread, but I still need to adjust the tune to get rid of the flutter completely. Here's the way I hooked up my boost controllers: http://i596.photobucket.com/albums/t...brid_setup.jpg I used a 1 bar spring (14.5 psi) and I am running 21 psi boost. Hope this info is useful to anyone who is thinking about getting an EWG! Last edited by Mr Wrex; 11-11-2012 at 09:30 PM. |

I can't tell if it's the MBC, EWG, or my lead foot, but my mpg seems to have gone down by 3-4 mpg after I installed these parts. Could it be from the MBC's insta-boost or the EWG releasing exhaust? Or is it just from me trying to scare the living crap out of every driver I pass?

Post #65. It starts at 25 seconds. FYI, you will hear a little flutter because I did partial throttle at first (which is when the EBCS controls boost) then went WOT (which is when the MBC controls boost) and the fluttering stopped.

I've read this thread probably about 5 times as well as done some other searching around on this site but I still have a question. I recently got a cobb ebcs, up pipe with 44mm v band, cobb dp, iwg bracket, and all that good stuff. My question is would I be safe for me to run the ewg set up without the ebcs for a week or so before I get a tune? I have a 1 bar spring and would be running 18.5psi with the stage 2 map. I know I need a tune to run the ebcs and everything safely but it's a slight drive to the shop and being a student I can't just leave when I please. I would just prefer to go ahead and install that stuff to save install costs...and well because how can you look at parts and not want to install them?

Just installing the DP alone is enough to require a tune or for you to stay out of boost until you get one. If you were just installing the EWG, you would have been fine running the EWG off just spring pressure and you would need to disable the CEL that would be thrown by your stock BCS (I forgot the code #, but it relates to a sensor that measures the barometric manifold pressure. Maybe it was p108?).
Now maybe I misunderstood your intentions, so I will just assume you're planning on using the COBB stage 2 OTS map. Disconnect your stock BCS vacuum lines completely. I would still suggest the e-tune from Eric as that would be easy to flash on as soon as you install the parts and allow you to boost safely. I am currently using his stage 3 map with some custom tuning for an EBCS + MBC hybrid w/ the 38mm EWG and I friggin love it Last edited by Mr Wrex; 11-15-2012 at 11:28 AM. |

You should load the Stage 2 map and run wastegate pressure. Don't connect the vacuum lines for the EBCS, but keep the electrical connector plugged in.

You won't be able to hear your EWG go off until you get the protune anyway because you can't go safely into boost without killing your engine. Idk how you'll pull that off for an entire week because it's hard to resist going WOT to hear that baby scream |
