Hello, On a A4 b6 1.8T AVJ i need make conversion for propper scale of 440CC 0280155968.

I have change krkte using (old cc x new c) x old krkte. after a test drive the afr is good while cruising and wot on gauge but very too lean at idle (18) no o2 sensor plugged except a standalone for check.

Do i need to change tmin and tvub for resolve the lean idle or i can adjust it by other way ?

What is the factor of voltage offset in Bosch the data sheet ?

On the net some peoples says that data are incorrect , it's true ?

These are not linear, you need to work with FKKVS
But first set good TVUB

What do you think about tvub from the data sheet ? You agree they are incorrect ?
