For pump current=0mA, Bosch datasheet says lambda =1.027 (1.03 can be displayed, maybe 1.04, there is always some margin in measurements).

Some other devices display 1.00 (or 0.99) for the same circumstances.

We recommend tuning the LSU4 to Bosch specs (regardless of other vendors; the "real" value is very complex to measure).
