I have an audi s3 8p and when I was using a motorola device the vacuum reading was working. now I switched to a samsung a6 and read no more. could anyone give an aid? the boost is reading normally.

You might want to check the boost
calculation method under adapter
settings for your new device.

the sensor information in the torque shows as the last value the 0. However in vcds I can see the information of the negative pressure the vacuum.

It seems odd that Boost is working but
vacuum is not since Boost=MAP-Baro()?

What is your MAP sensor showing?

With KOEO does MAP match atmospheric
conditions?

As I said if I use the vcds the vacuum appears with the correct value. only at idle we have 280mbar in vcds. where 1000mbar would be equal to 0 bar

Still curious what Torque’s MAP sensor
is displaying. (Intake Manifold Pressure [0b]).

The absolute pressure should show
vacuum below 101.325 kPa.
