Description
OMNI Power 4.0 Bar MAP Sensor – Subaru WRX / STi V3-6 (1996-2000)
This OMNI Power MAP sensor is a direct plug and play upgrade sensor for an easy install and an OEM look. While the factory MAP sensor supports boost levels up to approximately 17PSI, beyond this level a MAP sensor upgrade is required. This OMNI MAP sensor reads up to 4 Bar absolute pressure, meaning that it is suitable for applications running up to 3.0 Bar (or 44psi) of boost pressure.
ECU re-calibration is required after fitting this sensor. The linear calibration for this 4 Bar OMNI MAP sensor is already pre-loaded on many aftermarket ECUs (including Link G4+ and G4X models). However, in case you need to enter a custom calibration into your ECU of choice, calibration data is:
-
Calibration points are 20kPa absolute = 0.2V, 400kPa absolute = 4.8V or using Link G4+/G4X ECU’s just select the MAP sensor type as ‘4 Bar’
Note: The reduced resolution of a 4 Bar MAP sensor (over lower pressure models) is not an issue on modern high-quality ECUs that use analog-to-digital conversion with 10bit (or higher) resolution.
