3 BAR MAP SENSOR

Manifold Absolute Pressure (MAP) sensors, have two specific responsibilities in the engine management system: measuring barometric pressure at key on, and to report engine load to the powertrain control module. The powertrain control module uses the information for proper air/fuel mixture control under performance driving conditions. For example, a 3 BAR sensor will handle a forced induction up to 29.0+ psi of boost. We use this measuring and reporting to build more powerful and more stable tunes.

Clients wanting higher boost levels in the EcoBoost platform should consider this, as the factory sensor cannot read anything above 14.5 psi. And some boost spikes can cause the sensor to rise above that.
*Not needed for EcoBoost F-150 applications.
