You literally need to read how an engine works to understand that what you are proposing is ridiculous and will not get you anywhere. Clearly it's not sufficient when we tell you.
No abuse here.
ok. thanks. i try to read more about engine works. so, do you know how i can decrease fuel consumption? do you have any suggestion for me? |

You cant spend a 10 min to read engine basics and air fuel ratio
Seems like some kind of trolling here but why?

Oh yes you can. It is possible to do it on a direct injected SI engine with continuously variable intake and exhaust camshaft phasing or a direct injected diesel with VNT turbocharger if they are not optimally tuned from the factory. On 1.8T you can't. |

I refer to the ECU he's talking about, which is not DI. |

A modern engine is nearly always optimally tuned for factory. Optimally for a ratio of emissions and fuel efficiency. If you throw emissions out of the window, then you can make some small fuel efficiency gains. |

Exactly. In my country I pay over 50% "Eco" tax on every liter of fuel I put in my car, so F*** emissions, I want my engine as efficient as possible. In some cases, especially with diesel engines, there are quite substantial gains to be had. |

thanks bitmap. in my country gasoline price recently increase 200%! and most car here are pollutant. my car consumption is 12 liter per 60 miles :| and i eliminate car Catalytic converter (because its very expensive). now my car injection parameter is 4.5 ms(whereas in standard car is 3 ms). i want just make some small fuel efficiency gains. it's possible i lose some HP and it's not important for me. so, in this topic ( http://nefariousmotorsports.com/forum/index.php/topic,530.0.html ) most of the talk regarding to lambda operation will directly apply to my car as well? |

unicornux: don't waste your time.
I tried to improve fuel efficiency on 1.8t and everything I did made things worse.
Best thing you can do is to keep car in best possible working order or buy something newer with more potential for mods in this regard.

now my car injection parameter is 4.5 ms(whereas in standard car is 3 ms).
Removing the cat will not affect that (excluding cat heating, before some mouthbreather comments). |

there are a million random day to day ways your car is going to eat more fuel than the miniscule benefits you'll get tuning the car for fuel efficiency over emissions.
If you wan't to save gas, the best way was already recommended above.
Limit KFPED to 25%
Enjoy your slow waste of time and effort.
