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
E6H/E6M 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.
