Yeah - won't really work with the LR Puma 'cos the engine management light will come on. Folks tried these on the Puma Defy a few years back, drilling different sized holes in them etc to try to get the EML to not come on, but then, you're still basically using the EGR......Get a Alive/Bruce Davis/BAS or similar flash remap and your EGR issues are gone forever. It completely disables it without the Engine management light coming on...

It's all very well for your add to tell you straight up that the light will come on, but what if it would have come on anyway for another issue? You wouldn't know. And I mean - reprogramming the ECU! That's what getting a flash is.

The flash upgrade from BAS/Alive etc is about $800.00 but not only do you get the EGR taken out of the equation, you get better torque and power and, ironically, substantially better fuel economy. You can easily put the original factory map back on too (and then later return to the flash) if you need to take it to LRA under warranty.

What is the issue with the EGR valve and why does everyone want to disable it?

EGR recirculates exhaust gases into the engine. This leads to reduced combusting temps, but it also introduces residue into the engine and causes an increase in fuel consumption.

one of the worst automotive inventions ever. get rid of it asap!

when you turn your truck off you can hear a quiet shaka shaka skaka. The is the EGR cleaning itself. When t starts to fail it sounds more like a chook with a sore throat. You still drive the car but fuel consumption drops away. So much so I was getting 330lm out of 65lt at one stage.

LR will happily keep replacing them under warranty, however when out of warranty it's an annoying cost that seems to re occur every 30 to 60K klm.
A remap, until this thread had been the only way to blank it off.

My local indie claims to have a blanking plate/removal method that does not cause the MIL to come on. Will investigate more in Feb 2013 when my landy is out of warranty.

At the same time an Allisport intercooler is going in :angel:

Thanks for asking that question Samblers, I've been wondering for awhile. To those that have done the EGR block, by how much has the fuel consumption improved?

Sounds ****. Why put it in in the first place?

[noob question no. 2 :) ]

Stock standard, my landy was returning 11-12l/100km, empty.

With a BAS EGR-closed only remap, i.e., stock standard performance minus EGR, we got 10.4l/100km on a 6000km trip to Namibia, *fully* loaded (RTT, camping gear, fridge, 2nd spare, etc).

I calculated that the remap cost has already paid for itself in fuel savings ;)

Reducing combustion temperature also reduces emissions.

I get about 10% better fuel economy with my remap. The problem with EGR valves is not just one of economy though....once they soot up, you'll notice surging on the throttle...it's very annoying, and it's caused by the EGR valve sticking in positions rather than freely moving between closed and open as it should.

A flash remap, for the chap who asked me to elaborate via PM, is a reprogramming of the ECU. This electronically disables the EGR valve (meaning it is set shut and stays shut) so no exhaust gas is recirculated. Not only can't this valve then stick and cause surging, but no dirty burned fuel is recirculated back through the cylinders and the engine breaths and remains cleaner. The engine management light won't come on because of this disabling, and still works for any other issues the light might be activated for, so other potential problems won't be masked.

I guarantee that any Puma owner that gets into 6 figure mileage with their vehicles will find issues that are directly attributable to the EGR valve. They are required to be fitted under EU emission laws; the irony being you'll use less fuel and get better performance with the thing disabled.

My remap also boosts power and torque... Power by 20 odd percentage (from memory) but with 100 extra Nm of torque. Bigger performance gains can be made too with further mods (larger intercoolers etc). Although others post to the contrary, I do not believe anyone makes a blanking plate that will not activate the engine management light (if the valve is blanked, it's just not possible to prevent without software modification) without the plate having drilled holes to allow some airflow. And if you do that, you haven't blanked off anything really, and with further km the problems will return.

I have a Bruce Davis flash.... It's the same as an Alive tune (under license from Alive) with some mods for Oz conditions, and contrary to what others here will say, Bruce will also provide the Atric consul so the owner can put the factory map back in cases where the vehicle requires Land Rover Australia servicing. My setup includes a consul - you just need to ask for one. (I never use LRA anymore anyway and my vehicle is all the better for it!)

I have an ATRIC remap that seems to do the job well - ie it tweaks the rail pressures and switches off the EGR. To be quite honest i don't see any massive improvement in fuel economy; it seems that engine revs & gear ratios/changes are set so you tend to burn the same amount of diesel.
What you do see however is a MASSIVE increase in power, especially when towing. EG: I regularly made the run to Bendigo (Victoria) towing up steep hills pre-ATRIC and post. Defee backs right down to 50-60km/hr 3rd gear up the steep runs normally; with remap and EGR shut I cruise up at 90km/hr in 5th (in fact done in 6th at 100 km/hr too but only as a test; don't recommend using your 'lightest' gear regularly whilst straining under load).
As mentioned, ATRIC allows you to reset ECU to original map when you go to the st(d)ealers which is necessary else they might reset everything and mess up your remap. This means the EGR switches back on. Recently I went in for 70K service and the EGR is 'squawking' like a chook - possibly due for a failure as others have mentioned (30-60k failure) or possibly partly to being closed as soot buildup accelerated (either way it would have happened). Dealer replacement @$550 as I am out of warranty period. I too am interested in a permanent blanking kit but ATRIC/Alivetuning do not do (except for TD5). This is the response they gave me only today when I queried..."If the egr is shut, then it will never need to operate. You could make a simple blank plate from a bit of sheet steel, which you could place between the exhaust manifold and egr valve. We don't have these, and never had needed them, so don't have a pattern."
May not solve problems of 'warning light' or having to reset to original map for dealer servicing so if anyone has any ideas I'd be interested too.
Hope this helps a bit!!

I'd say 2 things.....

1. A blanking plate is completely unnecessary if you use these remaps. Shut is shut! Mine sounded like a chook without remap - that's why I got one. Sure, a plate (added in combination) would prevent chook impressions when standard tune were selected but the EM light would be illuminated so the dealer would be wise to it anyway, and you would be unaware of masked issues that may arise during the period you were using such a configuration. Just leave the map in place! I have a consul in the event that years down the track, if I inadvertently use a dealer and they put the latest LRA software on, I can **** it off and restate my map.

2. My driving style hasn't really changed post map...I drive conservatively, still do - and now I get 10% better economy no doubt about it. The odometer doesn't lie.

Thanks for the info. My understanding from atric was to always return the ecu to original when take to mechanic/dealer. If dealer overwrites then could cause problem when you reflash the ecu. Is this correct? If true will always have the "chook" noises even for short period while in service. Hence the desire for a more permanent physical fix

[Gerokent]

I know it would be a lot of stuffing around, BUT, would it be feasable to re-route the EGR back into the exhaust system thus bypassing the intake manifold?

The only reason to ever take the remap off and replace with the original factory map is if the vehicle is under the original 3 year warranty and you get it serviced by LRA. This is purely because the remap may invalidate your warranty. If you reinstate the factory map (which is the 2nd file on your ATRIC consul), no one is any the wiser....your vehicle is stock, no question, no potential warranty issue. Obviously, the fact that you have an ATRIC containing a remap is your business and not information to be shared. ;)

In this circumstance, if at the time of service, your factory map (that you just replaced) is again replaced by the current LR factory map, all you need to do is hook your ATRIC back up and reinstate the performance remap you bought using your ATRIC consul. Simple as that. There will be no issue at all re-flashing it. You can replace your remap with your standard tune yourself - anytime, and then replace the performance map without issue using your consul....you can do it, I can do it, the bloke next door could do it if we have your consul ....so there is no difference if the dealer removes your factory map (or even your remap for that matter) and replaces it with a current factory map....you simply put your performance remap back when you've finished at the dealer's workshop...

If the vehicle is out of warranty and you still use a LR dealer to do your servicing, you could simply ask them to leave your map as is. I have the consul in the event that one day, sometime, somewhere, if I get my vehicle serviced by a dealer (say on a big trip away from home) and I forget to tell them to leave my map as is, and they inadvertently put the latest LR software on in it's place (which I don't want because my chook will be awakened!).....If that ever happens, I'll just replace my flash before I drive off.... It takes all of 4 or so minutes and is trivial.

Again, there is absolutely no reason whatsoever to fit a blanking plate if you have these remaps. :)

Thanks for helping us get over our delusions of EGR grandeur! I'm rapt with the atric console & it's good to know about being able to overwrite anytime. One thing also advantage with console is you have ability to clear & read faults at anytime too. After this I am currently redoing my fuel economy assessments (original vs remap)

this might be a stupid question scallops but did u fit this yourself if not were do i get this done also can you get imobilizer taken off because i could see that giving trouble 1 day

It's not a fitted part - it's an ECU software update. But yes, as it happens - I did do it myself, which simply involved plugging the Atric into my vehicle (panel under RHS of driver shelf) and selecting the performance map file. :)

[Samblers]

How would you go regarding insurance if you disable the immobiliser?

Hmm... I suppose if the vehicle gets stolen then no one will ever know... :angel:

I don't know. But I do know that this ECU remap does not disable the immobilizer. It does, however, disable the speed limiter (if programmed in original factory map) :)

[red roo]

Do you know off anywhere in vic i can get atric consul and remap

All of the flash things listed only specify the 2.4lt puma, does anyone know if the 2.2 would work?

The corresponding software for the 2.2 is still a work in progress.
