Turbosmart FCD-2 Electronic Boost Fuel Cut Adjusters

These Turbosmart FCD-2 electronic boost fuel cut adjusters are designed to alter the output of a factory 5 V MAP sensor or AFM at an adjustable level to accurately raise the factory fuel cut point. They feature LED indicators for an easy setup and have an adjustable release, ensuring that you retain the safety of having a fuel cut to protect your engine from over-boosting. The Turbosmart FCD-2 electronic boost fuel cut adjusters are suitable for most turbocharged cars and are designed to be used in conjunction with a Turbosmart boost controller.

HOW TO INSTALL YOUR FUEL CUT DEFENDER cont. The output wire of your MAP sensor or AFM can be easily located using a digital multimeter or consulting your service manual if not listed. When using a digital multimeter ensure the meter is set to read voltage in the 0-10V range. Place the negative probe of your multimeter on the vehicles chassis and with the car idling, slowly rev the engine. With the positive probe you should be able to read a change in output on one of the wires connected to the MAP sensor or AFM with increasing rpm. Alternatively with ignition switched and engine off, blow air through the AFM or apply pressure to the MAP sensor using a vacuum/pressure source. This should also give a change in voltage on the sensor output wire. Once you have identified the correct wire the wire should be cut and the input and output of the FCD2 should be connected to the wires as shown in the above diagram.  WIRING: Mount the FCD2 in a suitable location within the cabin using the supplied screws.
