Insofar as adjusting the code to cut out the EGR, yes. But it's not necessarily a remap to increase power/torque etc, that's a different tweak.

Its still modifying the software so may as well get a tweak at the same time.

I thought it also required some extra wiring components under bonnet that acted as the emulator to confuse the computer?

Not aware of that. I presume if it does require wiring changes it's part of the process. Apparently the EGR blanking and associated ECU changes is about $850, not including the remapping required to increase power/torque.

Incorrect for anything above around 2007 onwards. Beyond that age the ECU can detect a lack of flow through the EGR and will flag an error. This is why they remap the EGR mapping to stop it opening in software and expecting air flow through it.

My mistake if that is the case. I got a remap done at the same time as the blanking but thought it could be a separate process. Anyway we can beat about the bush with all sorts of remedies here, I guess the best way is to phone the guy and find out. As the ad says,,simples.

Mine has emulators plugged in but I assume that may be because my EGR units are fully removed for access to the turbos.

I might add that I cannot detect any difference between having the EGR's and not having the EGR's so I can't see why anyone would really bother with it unless you are trying to access the turbos with the body on. It has not changed fuel consumption either.

The filth inside the manifolds mainly but while it bugs me, not enough for me to pay a grand odd to map it out.
