Skunk2 is proud to offer our very own 3 BAR MAP Sensor for the Subaru BRZ, Scion FRS, Toyota FT86 and the Honda K Series engines found in 2002-2011 Civic Si, 2002-2006 RSX, 2004-2008 TSX, 2003-2007 Accord, 2003-2011 Element, and 2002-2006 CRV.
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:
- 1 BAR is for a normally aspirated engine
- 2 BAR will handle a forced induction up to 14.5 psi of boost
- 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.
NOTE: Compatible with BRZ/ FRS/ FT86 and possibly many others

Voltage to pressure (KPA) conversion
P= pressure in KPA 4 bar = 400 KPA
Voltage out/signal = 5 X (.00318 X P - .00353)
Example: Atmosphere equals 1 bar or 100 KPA = 5 X (.00318 X 100 - .00353) = 1.572 volts @ 1 bar
or 100 KPA
