Hello there. I am new to the forum and to the ecu editing and I would like to have the second 2 lambdas to be turned off.

Here you go.
Delete lambda sensors after cat.
Flash file.
clear all adaptions,
clear DTC memory.

Ready to run.

It really worked. Thank you. A friend of mine told me that if I upload a software from 525i 192hp its gonna work fine is that true? I cant find a good source of information about is it only software limitted to 170hp or there are differences in the engines. If you could help me out with that.
