Recalibrating map sensor offset

I suspect my wideband config is not right. If I set the fueling at idle that it barely wants to idle due to the richness (10.4:1 on PLX) I only get a lambda of 0.85..... and my PLX is 600mm+- from the turbo and my Vems wideband is 200mm from the turbo. I'm just looking for my config file sent when I got the system.

Send a mail to info @ vems.hu and ask for the calibration numbers for your ECU (give them the serial nr).

It means pump zero PW =100
and nernst DC target = 135

all rest values - default! Check that!
except Sensor free air calibration. You have to perform it.
