BAROMETER (range of .7 to 1.1 bar)

This is also in the MAS . It shows the barometeric pressure of the air to the ECU. This combined with other readings helps the ECU to know how dense the air is therefore to determine total air mass entering the engine.

On VPC cars, the VPC will tell the ECU that the barometer is 0.99 bar. This is also not adjustable on the VPC. If you have a dime store fuel cut defencer, this adjusts the barometer reading to make the ECU think it's at a higher or lower altitude. I've seen this work and cause readings from .84 bar up to .99 bar.
