Remove Post cat O2 codes Single Turbo only

If you have a single turbo you dont need to use the rear O2 sensors. Single Turbo only.

If you remove the sensors everything works but you will get 2 codes you cant remove and an engine light.

On Tunerpro
Left click Toggles
Left click Diagnostics codes
Right click DTC Master
Left click Edit parameter in bin

A heap of codes will pop up with 2 numbers next to them in a separate column.

Scroll down to 2C9E and 2C9F which is directly below one another.
Change the 56 to 00 snd save the table then save the bin.

Load onto car no more rear O2 sensors needed and no codes.

Step by step video Only 1 minute long. Not 15 minutes and what I had for breakfast sorry.
