What accessories are required to maximise your Link ECU? We sell a variety of sensors and extras which complement aftermarket ECUs. The Link 1.15 Bar MAP sensor reads up to 1.15 Bar absolute pressure. This means it is suitable for use in naturally aspirated engines. This MAP sensor can also be used in applications where positive intake pressures of up to 0.15 Bar (approx 2 PSI) are expected (eg. Ram-air effect). The wiring pinout for this sensor is marked directly on the housing.
