MAP = Manifold Absolute Sensor
The sensor is given by Bajaj in their new product which they have recently lanuched. Pulsar 220cc Carburetor Version.
Definition
The Manifold Absolute Pressure (MAP) Sensors (also known as a BARO Sensor) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). This is necessary to calculate air density and determine the engine's air mass flow rate, which in turn is used to calculate the appropriate fuel flow.
It is connected to the intake manifold on both EFI and Carbureted engines to monitor the changes in the vacuum (-ve pressure) that are occuring as you ride change speeds and vary the load via the throttle position. It is temperature compensated and uses a complex algorithm to help offset the pulsating wobble effect of the HD V twin's assymetrical firing setup.
It is a very major component of the final speed density calculation that ulimately determines the injector's pulse width required to sustain the best A/F ratio at any given time - for EFI setups. In Carburetor versions it assists in monitoring the degree of advance for the timing of the spark plugs. One more sensor with TPS on Pulsar BS-CV32mm carburetor.
On the carburated bikes, the spark timing curve is selected by the Ignition Module from RPM input and manifold air pressure input (from the MAP sensor).
In other words, engine rpm and engine load (manifold air pressure) both play a role in determining what spark timing is needed at any given situation.
