1.3 Expanded Installation Guide
1.3.1. Manifold Absolute Pressure (MAP) Sensor
The MAP sensor is used to convert the manifold pressure into an electrical signal for the E6K
ECU to use. The sensor works in absolute pressures, thus its calibration is not affected by
changes in barometric pressure. The vacuum and, in the case of forced air induction engines,
the pressure under boost, is proportional to the load under which the engine is operating and
the ECU uses the electrical signal as a load reference.
