Thread: EGR Emulators

Have you looked at the 4.4 TDV8's EGR valve's electrical connector? From parts diagrams it appears that it probably uses the same electric motor c/w connector as the 3.0 which would not be surprising, being of the same development era.

Is there more info on this somewhere?

The 3.6 has 2 drain plugs, with the rearmost one draining a reservoir from at least the RH turbo drain but its often not removed during oil changes so sediment accumulates interfering with the turbo drain flow. The 4.4 has a similar rear drain plug but no main drain plug.

If the TDV8 EGR stays open longer on startup I can see why these motors don't like short runs, which is what I often do. However, I haven't noticed a change in the sound of the motor after its warmed up.

Yes the plugs are easy to access. Your site mentions the RRS, but I assume it also suits the TDV8 RRV?

[QUOTE=Gally;2489214]NO the butterfly is left in.

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.


Do these emulators need a power source of some kind or is it built in ?.

Might actually be better to unplug both rather than just one, in case it does funny things to the engine running one emulator and one standard issue.

How much????
I assume one simply unplugs before goint to a dealer and nothing can be detected???
Sounds great.

Are you aware that you can get your ECU remapped with software written in that keeps the EGR vales permanently closed? - thus never having an issue with coked up EGR valves sticking open and causing 'limp-home-mode' or complete lack of power....or the 'screeching' of EGR vales going through a self clean that is only good for a limited time????

Had my ECU remapped on my 2.7L 2010 D4 both for performance and EGR fix and have been smiling ever since. Dealer workshop know it has been modified after a test drive and comment as such but completely undetected by LR diagnostic equipment. Wasn't cheap but the best $$ I have spent on the car

This is a great way of doing it if you are wanting a remap, but for me, I don't want or need a remap yet. I would like to disable EGR but I don't have any desire at the moment for a remap. Maybe one day I will get the ECU tuned, and then I will also disable EGR, and would then probably on sell my EGR emulator kit to someone who would like one.
