The name Haltech has become synonymous with quality, reliability and performance over the years, owing to their constant commitment to providing the auto market with the finest products to help drivers get the most out of their engine and their vehicle.
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.
This 4 bar MAP sensor is capable of reading intake pressures up to 3 bar of positive pressure above atmospheric (otherwise known as boost). This is equivalent to around 44.1psi of boost or 300kpa of positive pressure. This sensor is suitable for turbocharged or supercharged vehicles running between 15psi and 45psi of boost.
