Multiecuscan

I With the MES I tried to run the Adjustments functions after replacing two components, in particular that of the MAP and the Lambda Probe, the first did not give any error, the second, however, reported "Status: UNKNOWN" (see the link), Why?
I connected the MES to the car with the key on as suggested and I tried to generate some graphs by selecting some parameters of interest... but I get nothing beyond the static data of the previously selected parameters.

Are the graphs is needed to power-on the car?

Thanks a lot.

With the engine not running then all you will see is static data. Try again with the engine running.

Thanks a lot.
And related to the error reported in the link?
