e91 code out o2 sensor

paolito · 01-25-2023, 08:43 AM

Hi all, so i successfully managed to upgrade 318i to 320i ecu. The car has a little bit more grunt. it is definitely noticeable.

Everything works fine except for EML. The 18i has got only 2 o2 sensor the 320i has got 4 lambda. Clearly the car things 2 o2 sensor are broken.

anybody can help me coding out the o2 sensors?

thank you
