One for the wise and experienced...

Hi Guys

I live in Sydney and have just has Mark at Auto Code do my ECU on my 2007 TDV6 ERUO4 engine.
I got the EGR Delete and ECU Remap done.
I had to remove the ECU which wasn't a huge job. Less than an hour.
I Express posted it out a Thursday afternoon, Mark did not get it until Wednesday Lunchtime. (well done Australia Post)
I spoke to Mark about what Tune they use and he told me that they had a lot of time to developed, test and fine tuned these adjustments
all in WA over a number of years.
I received my ECU back on the following Wednesday Lunchtime, so I was without the car for almost 2 weeks. I have a company car so I did not worry about it to much. So if you are looking at this be prepared to be with out your Disco for more than a week.
While I was waiting I installed the EGR blanking plates, Sundely brand for $24 on ebay. nicely made.
I got the ECU installed and fired it up. Idles nicely. Took it for a good drive and the first thing I notice was the responsiveness of the accelerator pedal. Much Much better, Feels really good and quicker off the mark and is very smooth through all the gear changes.
Very happy with the result, No error or warning lights and at cursing speed looks to be using slightly less fuel.
One thing I have notice is when you turn the ignition on I don't get the clicking sound from the Engine bay anymore.
This must have been the EGR positioning test function before starting.

Only negative is Mark is a bit had to reach on the phone and takes a few days to get back on emails. Must be busy.
Still waiting for an Invoice to be sent that I have asked for twice in the last week.

Did you remove the butterfly in the intake housing when you blanked the engine? Is prudent to do this on a blanked engine.

If you leave the butterfly flap in place then you could put the engine in a situation it was never designed for, EGR closed (due to being blanked) and butterfly closed (as on overrun) this would create a vacuum/depression within the engine, that could cause damage to engine seals etc as well as other issues.

Is it true the blanking plate must have a hole in the middle to allow some continued airflow or it might throw a fault code because of air pressure?

Of course, it should be noted that blanking the EGR means the vehicle would probably fail an emissions test if it was ever tested. Failing an emissions test could make the vehicle unroadworthy as it would not comply with the manufacturers specifications to meet emissions laws at the time it was released to the market.
If the vehicle was found by an inspector to be unroadworthy because it had been modified by the owner the registration could be cancelled and the insurance company could refuse to payout on a claim, so the owner could end up with a worthless pile of spare parts.
It does happen. I don't know about all the states but I believe Queensland has a mobile emissions testing scheme. In Victoria 10,000 vehicles were required to be tested last year. Owners are sent a notice requiring the vehicle to be taken to a testing station by a certain date. If the vehicle fails the test or the owner fails to present the vehicle for testing then the registration can be cancelled and the owner fined.
So that's a risk those who blank their EGRs are choosing to take. Hate to be a killjoy, but I think people should think carefully about the implications before rushing into modifying their vehicles.
More than a thousand Australians are said to die from illnesses associated with vehicle emissions in Australia every year, which is similar to the road toll from crashes, so this is a serious issue and it's not going away. If anything the enforcement is likely to become more rigorous, particularly following the VW 'dieselgate' scandal. So, think carefully is my advice.

Hi Gary
I did ask the question about the butterfly flap and was told by Alex at Auto Code that it was not necessary to remove.
Might also be controlled differently by the Remap.
I was also told that I could leave the pipes on as well and didn't need to worry about the blanking plates. But if the EGR valves still leaked even when the valves were closed it could bring up fault on the ECU.

I strongly suggest you remove it....

Under overrun conditions it’s not doing your motor any favours..

Also very odd that he opened an early ECU like that when a simple OBD Access is possible.

Tampering and removal - correct, non-compliant.

Road side sniffer test - All BAS tunes will pass. Can not speak for Autocode.

Thanks Tombie for the advise.
I will look at removing the flap asap.
