LCD shows lambda too lean

[Tcal]

So if i rev engine like steady 2000 rpm, MT shows lambda 1.0 as it setted in lambda table, but in LCD it´s usually 1.03 or 1.04. What ´s causing this??
I did try to change those lcd setups...

I think the LCD data is the raw data?? Its direct of the serial bus, Megatune is not. You will also notice this with the TPS and coolant temps as well, i would be more inclined to believe the LCD than Megatune
