Thanks for the data.
If I read the table correct, then there is EGR is ONLY active from idle to 3000 rpm when the load (TQ) is below 267NM.
Above 3100 rpm and/or TQ>267 NM the is NO active EGR.
That somewhat makes sense, because the emissions will be measured at low power/rpm usually.

Yes, not at idle but active at part throttle closed loop operation. Has no effect during aggressive driving.

Fab a delete plate for the EGR-to-intake manifold opening and another for the tube-to-exhaust manifold opening. So long as it's tuned for it, it shouldn't be a problem. Not sure if the system can detect the missing EGR module itself (if so, you might need a resistor plugged into the wiring harness where the EGR module plugs in). Easy test would be to unplug the wiring harness to the EGR module and see if your car throws a new code for that.
With the V-Tech ECU Tune I ask for the EGR delete : can I pull out the EGR module (and Fab a delete plate for the EGR-to-intake manifold opening) without any default on the dash board ?

You don't need to pull the EGR module out, just blank it off with a 22mm threaded hex cap screw. We can code it out.

Thanks Stuart,

I've the ECU Tune with EGR delete and I've installed a plug but I need to remove the EGR and I want to know if I have a fault code or a warning light.

Thanks

AFAIK you can completely remove the EGR system and use a blank plate to seal the opening. The EGR delete tune will prevent any warning lights.

Not sure I understand 'remove the EGR' - you are talking about blanking off the hole on the headers?

So, if you have our Gen 1 headers, they do include the take off point for EGR on the headers. Our Gen 2 headers delete this entirely. Blanking off the port on the header, and inserting a bung into the hole on the EGR will disable the system, and if you have our ECU Tuning set up for this, will not throw any DTC codes. There's no need to remove the actual EGR unit from the engine.

Of, course you could always put a catch can in the car, that would solve almost all the problems associated w/EGR's.

I'm obviously a huge proponent of oil catch cans, but these are two different things.
The catch can prevents oil vapors from the engine block from getting recirculated into the intake manifold.
The EGR delete prevents exhaust gases from the exhaust system from getting recirculated into the intake manifold.

I've got a catch can as well as VAP headers (gen 1) w/ EGR delete on my grey V8V. Both beneficial for maintaining clean intake air, but different in how they do that.

I want to do as Richard :
1 - Delete EGR
2 - Delete the AOS and install a oil catch can (like the GT4)
