Ways to disable turbo ?
I'd like to flash back to the stock rom for the purpose of ecutek data logging but not interested in removing the turbo kit(AVO). This would be short term setup specific for capturing some logs.
Anyone have thoughts how to impede the turbos ability to create boost without removing it? I was thinking a small check valve on the BOV vacuum line(full recirculating) so vacuum would hold it open but not sure if no load on the compressor is bad thing as it would probably spin faster than normal at WOT. Thanks for your thoughts. |

even bypassing the wastegate will still let the car boost to the spring pressure of the wastegate...I think
So if the spring is the wastegate is 5lbs, the lowest you can boost is 5psi but bump |

I'm not sure you'll ever get this to run anywhere near stock even with the turbo disabled. You'll still be running very foreign headers with extra restriction from however you disable the turbo.
What exactly is your purpose here? We may be able to suggest a better alternative if we know what you're truly after. |

Can you expand more on why you want to do this? It all sounds like a horrible idea. I am not sure if the MAF placement on the AVO kit will even work with the stock ROM MAF scaling.

Agreed with above. Their would be two ways I can see doing it, both of which likely won't revert the car back to a "stock" engine VE. You could somehow force the wastegate to stay open all the time, but the turbo would still be turning and probably create a little pressure in the intake. You could somehow force the BOV open at all times, then you're venting any air that the turbo builds, but you're also sucking in un-metered air.
This sounds like a bad idea all around... and for what purpose? |

"tip in" is how I think people refer to it. There was a member @jamesm who was posting some really interesting information about it but I see he is banned now for some reason? This isn't the Software tuning section so I don't want to get into it to much but I've driven the car with the turbo and stock rom before but I'm not able to get the IAM to rise to 1 because I can't load it without the boost rising to quickly. So that's all about the why. The MAF stays in the stock location wit hthe AVO kit so swapping the MAP to OEM is all I expected to do to keep the ECU happy. I hadn't thought about all the extra restriction on the exhaust side. It probably wouldn't be a valid log anyways if the header and impeller make such a difference in back pressure. |

You can either take the spring out of the waste gate (assuming external) so all the exhaust will dump or take off the bov and let the boost leak out. Either way though you won't get proper readings because you will either have an exhaust leak bypassing your O2 or a boost leak bypassing the MAF. You aren't making boost at 1300 rpms so the turbo shouldn't have anything to do with it.

Thanks for the ideas. I realize the whole thought is out there on the edge of "wtf did he just ask" but I regret, just a little, not putting more miles on before the turbo. I only put 1k miles before the turbo kit went on. In retrospect I would have done some logging and gotten more of a feel for what a stock car is like. throttle feel, normal engine sounds etc...
Fiddle with the wastegate (internal) seem like a good idea. Maybe I'll try to pin it open or something. |

I wouldn't do this unless you had to limp the car or something. I would never WOT this disconnected turbo setup.

Sounds like a winner. I didn't really want to take the under tray off to get to the turbo... again.... but probably a good place tackle this. Thanks.

If he loads up the stock tune I can't see any problem with it. With the waste gate arm disconnected the turbo shouldn't build any boost due to the amount of exhaust flow escaping. Plus I believe he is only testing the lower RPM range.
