SpeedFactory Racing 4 Bar Map Sensor K-Series K20 K24 Red Flywheels The characteristics of 57XR areOur SpeedFactory 4 Bar MAP sensors use state of the art bipolar op amp circuitry with thin film resistor networks built into each microchip. Pressure changes are calculated on a true linear 05 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
