Haltech HT010130 Ecu Inputs - Map Sensor

Description

Bulkhead Hose ConnectorSuit MAP Sensor HoseA Haltech MAP sensor (manifold absolute pressure)provides instantaneous pressure information to the electroniccontrol unit (ECU) from the intake manifold theamount of boost or vacuum in the intake manifold. This is necessaryto calculate air density and determine the engines air mass flowrate or in other words engine load. Engine load is used as areference for all base fuel and ignition maps.1 Bar Map SensorA 1 bar MAP sensor is capable of reading intakepressures below or equal to atmospheric pressure, for this reason a1 bar MAP sensor is suitable only for naturallyaspirated engines (ie not turbo or supercharged).2 Bar Map SensorA 2 bar MAP sensor is capable of reading intakepressures up to 1 bar of positive pressure above atmospheric(otherwise known as boost). This is equivalent to around 14.7psi ofboost or 100kpa of positive pressure. This sensor is suitable forturbocharged or supercharged vehicles running 15psi of boost orless.3 Bar Map SensorA 3 bar MAP sensor is capable of reading intakepressures up to 2 bar of positive pressure above atmospheric(otherwise known as boost). This is equivalent to around 29.4psi ofboost or 200kpa of positive pressure. This sensor is suitable forturbocharged or supercharged vehicles running between 15psi and30psi of boost.
