ABOUT THIS PRODUCT  
Thank you for purchasing your new Turbosmart Incabin boost controller (ICBC). This new model now has some great new features.  
These include:  
2 ramp rates of boost to give you the option of a fast rise in boost or a slightly tame rise for more sensitive setups.  
A wider boost adjustment range for wastegates with low spring base pressures.  
A new mounting bracket to make it easier to mount.  
IMPORTANT NOTES ON YOUR BOOST CONTROLLER  
Use only silicone hose that is the correct size and pressure rating for your application when fitting your boost controller – other  
hoses will be affected by heat and will eventually crack or split which could cause excessive boost pressure and engine damage  
Ensure that all plumbing is secured with clamps  
The ICBC connecting hose should be adequately shielded from heat and positioned at least 200mm from the turbine housing or the  
exhaust manifold  
A Turbosmart Fuel Cut Defender may need to be used in conjunction with your boost controller – refer to www.turbosmart.com.au  
The boost dial has a left handed thread, be sure not to over tighten as this will damage the boost controller  
RECOMMENDATIONS  
Turbosmart recommends that the Air Fuel ratio is checked once boost pressure is set  
Turbosmart recommends that boost pressure is set using a Dynamometer and not on the street  
Turbosmart recommends that a accurate boost gauge be permanently fitted to the vehicle  
Turbosmart recommends that your boost controller is fitted and adjusted by an appropriately qualified technician

Allow the engine to cool down before installing your boost controller  
Locate the pressure source port and the wastegate actuator port on the turbocharger assembly (refer drawing 1)  
Remove the factory boost control solenoid if fitted from the boost pressure supply port while leaving the solenoid connected to  
the ECU

.
Install the tee piece in the wastegate pressure line with the wastegate arrow pointing towards the wastegate actuator and run  
the tee piece pressure line into the cabin and connect it to the bottom port of the boost controller  
Run a second pressure hose line from the engine bay into the cabin and connect it to the top vent port  
If your wastegate actuator has additional ports, these will need to be blocked  
Secure all silicone hose ends with hose clamps

SETTING BOOST PRESSURE  
IMPORTANT NOTES ON BOOST PRESSURE ADJUSTMENT  
Adjustment to your boost controller is made by rotating the Boost Dial  
Rotate in a clockwise direction to increase boost and the reverse direction to decrease boost  
Before making any adjustment, the Boost Dial will need to be fully closed (anti-clockwise)  
rd  
th  
Step 1: Apply full load to the engine in a high gear (at least 3 or 4 gear) at full throttle and note the boost pressure  
Step 2: To increase boost rotate the Boost Dial clockwise (maximum of 1 complete revolution at a time)  
Step 3: Apply full load to the engine and note the boost pressure  
Step 4: Compare the actual boost pressure with the desired boost pressure. If the actual pressure is below the desired pressure,  
return to step 2. If the actual is above the desired boost then decrease by rotating the Boost Dial anti-clockwise and return  
to step 3.  
BOOST SPIKING  
If boost spiking occurs and is undesirable for your application, the gate system can be removed to give you a less aggressive boost  
curve. This modification is only required in a minimal number of applications.

Ideal boost curve  
IMPORTANT NOTES ON GATE SYSTEM REMOVAL  
The gate system can be removed by the following steps.  
Perform this modification on a clean bench so that the ball and spring are not lost  
Allow the engine to cool down before removing the Tee piece from your vehicle  
Identify the input nipple with the restrictor at the end. Loosen the input nipple and remove the ball and spring.  
Check that the internal air passages are clear and free from debris  
Re-install the boost controller by following the instructions for your setup  
You will need to re-adjust your boost settings after the removal of the gate.

TROUBLE SHOOTING  
The following points should be checked if you find that your engine is developing excessive boost, the boost pressure is fluctuating or  
the desired boost level cannot be achieved. Please note the following checks will cure 99% of problems experienced when fitting a  
Turbosmart boost controller.  
Check that the boost controller is installed so that the arrow points toward the wastegate actuator  
Check the joining hoses for splits, cracks or loose connection and are the correct size for the application  
Check to see if the boost controller is blocked or contaminated with dirt or debris  
Ensure that there is nothing but the boost controller in the hose between the pressure source and the wastegate actuator, ie tee  
pieces for boost gauge or to factory boost solenoid.  
Pressure test the wastegate actuator for leakage, the diaphragm or housing may be cracked or split  
Check that the wastegate is operating correctly
