A Haltech MAP sensor (manifold absolute pressure) provides instantaneous pressure information to the electronic control unit (ECU) from the intake manifold – the amount of boost or vacuum in the intake manifold. This is necessary to calculate air density and determine the engine’s air mass flow rate or in other words engine load. Engine load is used as a reference for all base fuel and ignition maps.
Haltech 7 Bar "TI" MAP Sensor (inc plug & pins) 1/8 NPT
TI SENSORS MUST NOT BE MOUNTED DIRECTLY INTO THE INLET MANIFOLD, THEY MUST BE REMOTE MOUNTED AND CONNECTED VIA A FLEXIBLE HOSE
If required use Pressure Sensor Extension Hose HT-039103
