SPEEDFACTORY 4 Bar MAP Sensors. These sensors use state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip. Pressure changes are calculated on a true linear 0-5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes. The unique ability to compensate for temperature changes allows our MAP sensor to remain a minimum of 99% accurate from 32 degrees F to 180 degrees F through out its range of scale.
With the true linear pressure vs. voltage scale there is never a need to re-tune at different altitudes as with other sensors. SpeedFactory 4 bar MAP sensors can precisely calculate boost pressure from 1-43+ psi while still allowing smooth stock OEM drivability at any boost level.
Conveniently packaged in an OEM dimensional housing for easy install and an OEM look.
