The 1 bar map sensor can read from about 14.7psi vacuum (or negative pressure) to atmospheric pressure (0 psi). A 2 bar map sensor can read from 14.7psi vacuum to 14.7psi positive pressure (one bar vacuum, one bar pressure greater than atmospheric). In the same respect, a 3 bar map sensor reads from 14.7psi vacuum to 29.4psi positive pressure (one bar vacuum, two bar of boost pressure).
