TS-0303-1002 - Fuel Cut Defender - Instructions


Product Name:
FCD
Product Description:
FPR
Product Number:
 TS-0303-1002

Important Notes on Your Boost Controller

  1. 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
  2. The FCD2 is not waterproof and should not be mounted in the engine compartment. 
  3. The adjustment dials do not turn 360 , they start at 1 and finish at 10. Do not force them past these points as this will damage your  OFCD2 
  4. Before setup the unit should be set to the following settings, Clamp=10, Release=10.

Recommendations

  1. Your FCD2 is fitted and tuned by an appropriately qualified technician. 
  2. The Air Fuel (A/F) ratio is checked once the Fuel Cut Defender is set and/or boost pressure is increased. 
  3. Tuning should be performed on a dynamometer 

How to Install Your Fuel Cut Defender

Before Installing the FCD2

It is important to determine if the vehicles electronic control unit (ECU) receives its boost reference signal from the manifold absolute  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. 

Wiring

  1. RED Wire:  Connect to 12V positive supply from ignition switch (not directly from the battery) 
  2. BLACK Wire: Connect to Negative supply (earth/ground on vehicle chassis) 
  3. WHITE Wire: Connect to MAP sensor or AFM meter output signal wire 
  4. BLUE Wire:  Connect to ECU boost reference input wire (previously connected to MAP sensor or AFM output)




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.  

Tuning Your Fuel Cut Defender





Setting Examples

These setting examples are to aid in understanding the various settings of the FCD2 and should not be used as a tuning guide. 
IMPORTANT! See following instructions for tuning your FCD2.




For most vehicles the setup is quite simple. On a dyno, bring the engine onto full boost until the factory boost cut is activated, taking  note of the boost level at which this occurs. Then turn the clamp adjustment dial on the front of the FCD2 ANTI-CLOCKWISE until the  indicator light just illuminates. The GREEN LED indicator light should turn on just before the factory boost cut point. Activating the boost  cut defender any earlier than this could cause the engine to run “LEAN” resulting in possible engine damage.  With the clamping level set the release voltage or new cut point can be set. When the release dial is set to 10 the unit will release when  the sensor signal reaches 5.5V. If you know the boost level that you want the fuel cut to return with the aid of an assistant, drive the  vehicle bringing the engine onto full boost at the maximum boost level you want to run before fuel cut. Then adjust the release dial anti-  clockwise until the RED LED illuminates and vehicle begins to fuel cut. This dial should be set just above the maximum boost level you  require. Check the A/F ratio once the FCD2 has been set.
