Can i adjust my idle and mixture from only o2 sensor? (under the carpet)
Or must adjust it from x11 connector.They does same thing?So which is the best way?
When i try to get reading from x11 connector,its really complicated and jumpy reading.

I readed from different sources and i am really confused about settings
How must i adjust it?At 2500rpm?Or idle? (ideal 0.5v ?)
please clean explain
Sorry for my English.
