Programowo wyłącza się 4 sondy lambda robiąc downgrade dme do EU2.
Co da wyłączenie sond ? Jak wpłynie na silnik ? Czego można się po takim zabiegu spodziewać , lepsza praca silnika ?
EDIT :
Ależ mnie to korci ..
My DIY on How to flash to EU2:
1) Purchase the cable/software combo posted at the top of this thread, from the Romanian seller.
2) Follow the included video tutorials and install all software packages. Ensure they work.
3) Visit http://bmwfans.info and click on your E46 model, choosing EUROPE as the country.
4) Click on "Engine electrical system" then "Control unit DME, programmed". Note the serial number of the appropriate tune you want.
5) Open up WinKFP and enter the last 7 digits of that serial number when "Enter ZUSB" prompt comes up.
- Ensure you disable UIF writing
- Ensure you select LOW BAUDRATE before flashing
6) The flash will begin, it will take around 20 mins for the first stage, and around 3 for the second stage.
- Ensure you have a battery charger hooked up to the car supplying a minimum of 10A power.
7) After confirmation message, remove the key from position 2 for a minute and close WinKFP. Start DIS and clear all your adaptation values.

- Ensure you only use 91+ octane gas from now on.
