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 F9
ECU to use. The sensor works in absolute pressures, thus its calibration is not affected by
changes in barometric pressure.
There are three types of MAP sensors that can be used with the F9 system. The sensor
required depends on the engine setup.
1 Bar Sensor (Part No. 039 4070)
( -100kPa to 0 kPa) Normally Aspirated Engines
