If you do, let me know

The noise at start up is the control lines filling for the air ducting system. They are vaccum controlled.

Does it stay on for a bit after you turn car off?

 

[qqc d22]

So normal then? Also makes it on shutdown.
Thanks for the plate as well jjohn

 

[ourd40]

Must be normal.

 

[jjohn]

It is it is normal. Yeh it happens after key off as well.

Cheers qqc d22.

I would like to see the temperature difference thing proved so we know for sure how much it is.

 

[qqc d22]

Yeah I hadn't read the whole thread I assumed someone had done it and it as fine temp wise :/

There are over 30 pages in a thread in the D40 section and more in the D22 section and not mentioned b4.

Plenty of members have an EGT gauge and would likely also have the egr blocked so some one will be able to tell us.

temps are fine. it doesn't make it "hotter" as such it's just a more complete burn. sitting on 100km/h on the freeway i get just over 300c post turbo, i think i put the egr block in before i put the egt gauge on but at that temp it's not something i'm worried about...

 

[qqc d22]

awsome bods, thanks. It doesn't spike stupidly under heavy load or anything?

nope, not any more than i'd expect from a diesel engine running normally, still gets up hot enough when you are getting up it

 

[qqc d22]

sweet mate thanks for the info

 

[jjohn]

I have plenty of blank plates for yd25

got any ZD30 ones?

Im feeling kind of lazy but need to do the EGR block on my new truck.

No sorry, Dave does them tho.

did this myself about 10k ago, car has now done 25k, didnt notice any change whatso ever, still blows smoke aswell under power.

Mine was the same, i didn't notice much change at all.
But Since taking in out i think its blowing more smoke now

This thread has been dead a while, sorry if another has been started elsewhere. I read it from start to finish but it has left me with a question. I am certain that I have read on other threads (cbf looking for the link though) that the 2012 d22 takes an input from the egr to prove flow, but there has been no mention of that in this entire thread. It was further stated that to "fool" the ecu, a hole should be drilled in the egr blanking plate. One suggested a 2 mm hole, another suggested a 10 mm hole. So my question is, does the 2012 ecu require flow input throught the egr and if so, how big a hole do I need? Obviously, I don't want it that big that any gains by blanking are negated.

As an aside, mine doesn't blow any smoke at all and the turbo starts to spool at about 1500 or 1600 (but power isn't really noticeable till maybe 1800 or 1900). So is the mod still worthwhile? Does this motor still get full of crap without the mod? How about the catch can mod? Is that applicable to this motor? Most threads seem to relate to the 3L motor? Thanks
