Discussion: egr capped electronically

guys I wanted your opinion, I have the egr valve of my 1.3 mjet 90 hp closed electronically, then in theory it should work, or allow the passage of any thing, some friends told me that even if ? closed electronically in a bit always remains open, and then you can? clog up as if it were enabled, tales, or do you ? a shred of truth?? I opened this topic because? I would like to tapparla with a flange permanently in aluminum of the size of the gasket, but if you already? with the electronic lock and the same thing that the tappassi, then I leave everything as it is. thanks

You have said this, why? from the diagnosis to see 3-4% but really? ? closed.
The council ? always the one to clean it well and then close it electronically, and you will not have problems.
If you want to clamp anyone you forbid this, but ? a pi?.

so instead, if you stop only with the lamella and not in the ecu what problems there would be, considering that many of the close with the slat without remap. no light on say.

it depends on what type of egr valve and mounted on the motor.. there are various types of egr valves.. pneumatic, direct control with 5 wires on the plug where there is a potentiometer that informs the ecu on the actual percentage of opening of the valve and the last type, and indirect control with 2 wires on the plug that controls the percentage of the opening through the quantity of air that passes through the mass meter air on the latter will not be possible to close mechanically with flange

my reference was about 1.3 mtj thanks.

on some engines, plug with a sheet, the egr valve port some changes to the pressure of the turbo. If you have made some certain processing are things to keep in mind.

For example:

1.9 jtd engine . If you put the plate right at the exit of the manifold(the cio? the intake side), decrease the volume of the manifold and not just a little (see, for example, in the 105cv eliminate all of the metal tube). The result: obviously decrease the turbolag but you'll have a peak pressure pi? the top, just those peaks very harmful for the turbo.

They are expensive, but in some cases, make the difference

then I 83000 km I'm never open it polished the egr, 72000km when ? made the map and was only excluded electronically, and then you say I remove, clean, and to go and secure the cap with a strip?

I think you are right GIA. and then leaving a little I think it will go better,
