Blocking the EGR Valve

[growler2058]

I dunno if its my imagination, but she felt more responsive today after blocking the egr? Probably my imagination

[QUOTE=growler2058;650607]I haven't done my fuel filter yet. Was looking at it yesterday and it looked like a bastard to do!

undo pipes and remove filter with bracket attached that is what i did and was quite easy
put filter back in a quater turn so you can get to the sensor easyer

Your not the first to say it bloke.
A mate at work with a d40 navara said the same thing when he blocked his..

I didn't feel much on my 3L CRD when I had it. The biggest improvement was on my 2.5L CRD D22 Navara. When I plugged the EGR, it's as if the thing grew another turbo... I couldn't believe it !

By blocking the EGR doesn't it divert the extra exhaust gas
to the turbo, thus a bit more get up and go???

Thats what it feels like. As if its spooling a bit quicker

Well that makes sense. .
could also be that you have 100% clean cold air from the intercooler and not a mix of dirty hot air coming in..

How are people going in the crd's with a full block throwing the ecu into limp mode?
I wanna get this egr block asap but a scan gauge or what ever won't be for a little while yet..

There's no rush mate.
Remember the EGR is blocked at higher throttle settings anyway.
It only opens at idle/low settings to reduce NOX emmissions.

I would put a scan gauge or similar as one of your higher priorities.
It will tell you Boost, actual coolant temp, actual fuel flow, Alternator volts pus a few other handy things and read any fault codes.

Boost and temp are important if you want to start tinkering and actual fuel flow is bloody handy.
The only other gauge you need is an EGT

If you start dicking around with anything that you can't measure you are pretty much in the dark about what is really happening and I guarantee you the 'placebo' effect will kick in.

That's what I don't want to happen.
Any idea at what sorta rpm the egr shuts off?? Being a manual were changing around 3-3500rpm

EGR is controlled more by Throttle than RPM.

I used to drive my 07 CRD thru the gears relatively hard IE give it a bit of welly and changing at 3500 to 3750 give or take.
I find most CRDs like to get up to cruise or speed limit fast then back off and just tonk along.
It easily got the best fuel economy doing this around town rather than driving Miss Daisy which returned crap figures
IMHO if you have a high power demand that probably holds the EGR closed or close to it thru the gears as you accelerate.
