Round auto calibration

[fphil]

Hi,

We know that round should not need to be calibrated with respect to the LSU sensor it has to control since it takes into account a reference resistance attached to the sensor by the factory.

I have tested 2 new Bosch LSU with the same ROUND in free air.
Round gives 19.8 in one case, 20.3 in the other. I was expecting 29.8 - 30.0.
Any other experience?

Why would you expect 29.8 - 30.0 ??

Oxygen in air is 20.95%

glups, yes 20.9, this is what I was thinking !
Anyway the Round may need be calibrated again despite the factory resistance, in peculiar when getting old
