Only doing part of something results in only a partial result. Why would you expect anything different?.

Assuming you are in mexico or Aussie-land where you only need EGR ...

If you are seeking only removing the exhaust side of things then flash it with a factory-made mexican or Aussi file and unplug the main harness. No need for all the efforts and hacking you are trying to go through there. Those files are on the Incal collections disks that are found all over the internet. They can even be downloaded from the red engine maker themselves for free...

You need Insite to use the disks. Don't forget that the cans need to be hollowed out or removed after you get it working. The files in the pic below are already set this way from the factory. Make sure you use the right file with the correct injector size, turbo, etc. that match for components.

I never understood why people make things harder than they are.
