LL, is your FFRR remapped? ______________________________

After 2 month delay these bad boys finally turned up.

Been interested to see what they are like. Time for some data capturing...

I have thought about it and asked the same question. The best way to do that is on the exhaust side. But as the exhaust side of the emulator is not that accessible and it works ok as is, no one seems to bother.

There are a lot more of these emulators fitted to 2.7 tdv6 D3/D4/RRS LRs. ______________________________

I am intrigued by these, not seen them in the UK, we cant just block them as the ECM goes nuts, So it must be getting a return signal from something? I would have thought this would effect the fuel injection rate and timing?

I will be interested to see what your long term testing comes up with. Certainly seems to be a better option than remapping though a remap can be fine tuned to each engine.. 2018 L405 Autobiograpghy

surely a remap with a delete is just as easy and you get more power etc ?

G’day Dave
I look forward to the pics.

BAS also emphasised to me that butterfy valves must be removed if disabling the EGR, and couldn’t understand how my engine was operating with the EGRs unplugged and disabled in the closed position. The emulator designer advised the AULRO forum that when he did testing on the tdv8 3.6 and tdv6 2.7 the butterflies barely moved and didn’t close. Here’s what he said:
“I started the idea of the emulators about 3 years ago and one thing i was lead to believe was that the IMT (Inlet manifold tuning valve) or butterfly closed when the EGR's are open to restrict incoming air and only draw on the exhaust gas.

What i have found in testing is that the IMT rarely moves from about 12% open, even when the EGR valves are fully open, and instead causes a mixing of the gas, a bit like a swirl valve.

The engine always seems quieter at idle. it just sounds nicer. I think this is due to the fact that at idle the valves are open to about 85-95% and then work their way back to closed.

I have tested the warm up strategy over and over again and it is a minimal amount of time extra on the warm up without the valves. ”

But I’m starting to wonder if UK D3s in particular are tuned differently. ______________________________

I should add that emulators have been fitted to my 3.6 for about 20,000km without any dramas. I’ve been very happy with the product. And to be clear, I have no connection to the owner/developer of this product, only as a purchaser. ______________________________

I guess if it is quite at idle they must be mostly closed..., That's interesting about the butterfly post which i had not read.. thanks for that

It just seems to me that the egr removal situation is more than just this or just that and most owners do not understand what is going on... For me personally the butterfly's must go as they are a redundant component doing nothing but could be a potential problem.. and at the same time can only be restrictive, I don't think they will be hard to remove.. will take pics.. seems not many people have done them

As a side note when my map was been built and were going back and forth with Bas remaps.. we first did the egr blanking /closed positions before the remap so i got to notice the quieter sound of the engine straight away and drove the car with the main egr valve closed and noticed how much quieter it was... how much less throttle input i had to use to achieve the same acceleration.. different machine altogether .. as you would know

Another thing i have noticed as funny as it sounds is people getting confused between egr and dpf's

Thank god i do not have dpf's

It's crazy... people are often paying as much even more for the emulators!
