Skunk2 3 Bar Map Sensor BRZ FRS 02-06 CR-V 02-06 RSX 02-11 Civic Si 04-08 TSX K Series

A 1 BAR MAP sensor reports barometric pressure times one, which is approximately 14.7 psi or 30in/Hg (inches of mercury). 2 BAR or 3 BAR simply mean two or three times above barometric pressure. The sensor will measure each direction, vacuum or pressure.

For reference:

• 3 BAR will handle a forced induction up to 29.0 psi of boost

A vehicle's computer is calibrated to function at a specific level as programmed by the design engineer. A 2 or 3 BAR MAP sensor placed in a system designed for a 1 BAR sensor will not function correctly; in fact the system will run very rich because of the low return voltage signal. A computer that is programmable is a must for any tuner attempting to boost their engine's output with the addition of a turbocharger and a 2 or 3 BAR MAP sensor.
