    Default Holley MAT 534-20 - Sensor Scaling & Input Type

    I have an extra Holley 534-20 MAT sensor. I'd like to wire to a data acquisition system for an air temperature measurement. Several searches show the connector type is 570-216 (2-wire). In the Holley EFI software V5, sensor scaling shows 534-20 for MAT to have the following:
    Sensor min -40.0°F
    Sensor Max 999.0°F
    Does an input channel need configured for a span of -40°F to 999°F? Is the signal linear across this range or is there a custom non-linear scaling table? What input type is used for configuration? I believe this is a thermistor type sensor. Any additional information is appreciated.

    No, -40°F to 275°F is typical.

    It's linear.

    It's a Thermistor Type Input. Simply select it in the Inputs/Outputs ICF drop down menu (Configure screen).
    May God's grace bless you in the Lord Jesus Christ.
