It certainly would and has. I have been doing the remap and delete for some time with all models including the 2.2 and 2.4 Puma.

So many people in remote locations were asking me was there a fix without tampering with the ecu. That's how the emulators came about.

The beauty of them is, any body, anywhere in the world can just plug these in and its done.

Hi Gally
I'm interested in purchasing the emulators.

With fitting the emulators is there any consideration needed to be taken into account with regards to the fuel map. IE at high load can I expect that EGT will remain within a safe parameter post fitting the emulators or does it have no effect?

This would be on a stock 2010 D4 2.7 tdv6 which tows a 3.3 ton van.
thanks
Bob

Hi Bob, non what so ever. You will be fine.

A few of the guys here have come back from a trip over east. They had the Emulators fitted and covered 14500 km's towing 2 ton camper trailers and they said the weather was about 45 deg.

All went very well for them.

There's also a good customer of Rover Tech that has A TDV8 with them fitted and has recently done the Gib river road with no temp problems at all.

Thanks, Mark

I think with the other emulators, they need an external power source to be wired to and they are set to output a closed EGR voltage. The EGR map is then altered to 0% open, Keeping the ecu happy.

In the early days when i tried keeping the value to closed and editing the map i would often get the P0402-22 egr excessive flow detected, until the butterfly map was edited.

My emulators fully emulate an EGR, even the clean cycle.
On all my testing I have never seen the IMT close for the purpose of the EGR's

On all the ones we have trialed and fitted in the workshop the butterfly has been left in and there have been no running issues at all, with owners reporting on average 10% fuel saving and a noticeably quieter smoother running engine.

A few yrs ago I blanked my 2007 RRS tdv6 egr and removed the B/fly , and got a PO402 ex egr flow which I put down to the MAFF reading excess flow when the egr should have been open I guess , left it that way for about 5 months and no other problems or codes were evident . As I was not sure about the fuelling I put it all back to normal .
As you mentioned the same code in development I take it that I will not have to remap anything in my vehicle when I fit the emulator . Thanks 4 any info .

Hi, yes that's right no remap involved just plug and play.

Thanks, Mark

So I fitted the emulators yesterday. Hardest part was finding somewhere to mount them under the hood as I have an Optima yellow top in the spare battery cubby with no real room to mount the emulators. Less than half hour all up though. Took for 150km drive today - no error codes on my Gap diagnostic tool so all good there. Car still a sweet, quiet, powerful drive, only real difference noticed was the lack of squeak, squeak when turning the car off - a nice thing to be gone!

To be honest I dont care if I dont get better economy or power or what ever as I was already happy there. The main thing for me is that at my milage I am glad to have the EGR's closed permanently and avoiding possibly looming removal for strip and clean or replace - a PITA of a job and probably more expensive than the emulators (I cant do the job myself you see so would have to pay someone).

The product appears to be well put together, easy to instal and Mark is very supportive - sent me pics of how to install and advice on checking whether the EGR's were closed properly before proceeding with the instal. Now running some fuel additive for a clean up and wondering if I should also run some Revive through the intake system.

Well done Mark for a great product and awesome service.

You can have the 2.7 programmed to have the EGR's shut permanently and have blank off plates fitted, with out performance upgrade as well, Bruce Davis does it.
