Important notes on your new Diverter Valve

1. Turbosmart accepts no responsibility whatsoever for incorrect installation of this product which is potentially hazardous and can cause serious engine damage or personal injury
   
2. The EM series diverter valve is designed for use as a factory replacement for a turbocharged vehicle that utilises an electronic diverter valve, this valve can be used on other applications so long as there is a control signal to actuate the diverter valve.
   
3. Ensure the engine is cold prior to installation.
   
4. For Standalone ECU configuration, ensure valve is not energised for indefinite periods of time as this can cause significant life detriment to the actuation solenoid
   

Recommendations

NOTE!  Cosmetic engine covers may be required to be removed prior to the turbocharger assembly being visible.  

CAUTION!  The turbocharger assembly may require the vehicle to be raised on a hoist or jacked up and secured using vehicle jack stands, ensure your safety is not compromised. Identify OEM diverter valve location  

NOTE! Allow for the engine to cool down.

 

NOTE! It may be required to remove auxiliary components to access the diverter valve, ensure you consult your local specialist or a service manual for correct disassembly procedures.

Remove the OEM diverter valve

Remove the electronic plug from the EM series BOV and unscrew the flange screws in an anti-clockwise direction, completely remove and safely store the mounting screws. The valve will likely want to fall off the mounting flange as you unscrew the last screw, ensure you do not drop the valve as permanent damage may occur. Ensure O-Rings are kept with the valve for reinstallation. 

Observe the Factory Diverter Valve Recirculation Path

If your diverter valve has a flat featured on the flange (indicated in yellow below), this flat is to indicate the orientation of the plumb back ports relative to the factory diverter valve recirculation path. This is to ensure maximum recirculation performance.  

1. Diverter valve not actuating - Confirm electrical signal plug is connected appropriately, as the plugs are new, some force may be required to click the plug into place.
   
2. Valve is staying open - Confirm the valve has O-rings as they may have been dropped or lost during installation.
   
3. Boost Pressure loss or lower than before - Confirm the valve has O-Rings as they may have been dropped or lost during installation.
   
4. Failing the above, submit a technical request to tech@turbosmart.com.au with information of your engine configuration and photos of installation. 
   
5. As the factory engine control unit controls the valve, the diverter valve is almost silent.
   

Notes On EM Series Diverter Valve Operation

1. Due to its construction, your EM series may be much more audible than the OEM valve
   
2. During normal operation you may now be able to hear the valve open for a few seconds under the following events: traction control, cruise control management, rapid gear changes and varying throttle position changes. This is standard operation of your diverter valve and is coded as part of the torque management software in the OEM engine control unit; there is no adjustment available over these functions on the Turbosmart EM valve directly. It is normal for a diverter valve to be “very active” as it protects your turbocharger from surge events as well as bypassing air for torque management purposes.
