	Disable rear O2 sensor « on: July 02, 2016, 10:57:52 AM »

Hi all!

My friend has an Seat Leon 1.8T AUQ motorcode with a chiptuning. We would like to disable the rear O2 sensor. I found the topic which maps should be changed:
Set these to zero to disable rear cat DTC:
-CDKAT - Cat diagnosis in OBDII-Mode.
-CWDLSAHK (0x18663) - Code word for probe aging after KAT

The question is how can I find these maps at the binary files?

Thanks

Post your original file. And do you have any definition file or map pack for this BIN.

Currently I don't have the bin file. And I don't have any definition file or map pack for this. I read some topics about the definiton file creation but this is not an easy work.

You find the maps like you find any maps - using a comparison of the files. You need the bin, and a defined bin.

This is the "original" bin from the car. I have definition files and I checked that the required variables at the same place. The question is what variables should be set if the rear O2 sensor is totally removed?
