ABOUT THIS PRODUCT
Most late model cars have in-built defence mechanisms to guard against increases in boost pressure. Such systems are important but
can be an obstacle when increasing boost pressure
The Turbosmart FCD2 will allow boost pressure to be increases above the factory level and prevent momentary shutdown of the fuel
injection system.
IMPORTANT NOTES ON YOUR BOOST CONTROLLER
• Once the fuel cut defender has been installed, the factory over-boost fuel cut will no longer operate at the factory level. The boost
can now be raised to dangerous levels which can damage your engine if it is not capable of handling higher boost pressures. Be
extremely cautious when increasing the boost pressure above the factory level. Seek the advice of your local tuner or performance
specialist for further information
• The FCD2 is not waterproof and should not be mounted in the engine compartment.
• The adjustment dials do not turn 360
O
, they start at 1 and finish at 10. Do not force them past these points as this will damage your
FCD2
• Before setup the unit should be set to the following settings, Clamp=10, Release=10.
RECOMMENDATIONS
•
Your FCD2 is fitted and tuned by an appropriately qualified technician.
•
The Air Fuel (A/F) ratio is checked once the Fuel Cut Defender is set and/or boost pressure is increased.
•
Tuning should be performed on a dynamometer

HOW TO INSTALL YOUR FUEL CUT DEFENDER
BEFORE INSTALLING THE FCD2

pressure (MAP) sensor or air flow meter (AFM). Failure to connect the FCD2 to the correct sensor could cause severe engine damage.
Turbosmart recommends consulting the manufacturer service manuals before installation.
