can the egr be deleted Z30DT

As above is this possible as iv got a guy coming on wednesday to remap my car and hes only 85% sure he can do it.Any feedback would be great

I've got a 1.9cdti Z19dth, mines blanked and mapped out of the car, same with my dpf. MAS performance did it for me.

I have spoken to a few remappers, the EGR can be coded out.
Be very careful on who and how they remap the car, if all they want to do is raise fuel pressure then be wary. One of the differences betwee the Y30 and Z30 is that the turbo has an electronic actuator as opposed to a vacuum operated one so it should be possible to increase boost.
When you car does a DPF regen it increases injector timing to esentially over fuel the car, if a modest change in injector timing was made, along side a slight increase in fuel pressure and boost then you could be onto a winner.
I live remap would be the best way to go, that way alot of the different parameters can be chaged/tested.
Make sure that the guy remapping your car just doesn't turn off the EGR as this will still throw up the EML.

Thanks for the info Lee will let you know how i get on

I got in contact with the guy whos doing the remap and asked him what would be changed he replied

the following is changed

Torque rail turbo injection boost air and drive ability

[LeeU]

How did it go?
Who did the remap?
Hows it feel/drive?

Im gutted he never turned up i went to a few places yesterday and they all said that the ecu has to be removed from the car and sent off for remap.So i think he realised he couldnt do it and just never bothered showing up.

Lee iv noticed you have the same car as me do you know how many live wires are on the egr iv got 5 but only 2 are showing live.

[LeeU]

From the 5 wires attached to the EGR, according to the wiring diagram they are as follow:
Pin 1 - 5 Volt Reference
Pin 2 - Sensor Low Reference
Pin 3 - EGR Recirculation Valve Sensor Signal
Pin 4 - EGR Recirculation Valve Motor High Signal
Pin 5 - EGR Recirculation Valve Motor Low Signal

Not sure how much this will help you.

Cheers Lee i did another test with it plugged in and engine running and got 4 live wires and 1 earth so i guess the egr is goosed.Its unplugged at the minute but drives better than it ever did i can live with the EML lol
