FAQs


Here is a handy self-help guide to helping you with your Turbosmart install and answers to some of the most frequently asked questions we get here. 

Turbosmart recommends that you get your products fitted and tuned by a qualified technician. If you choose to fit and set the product up yourself, ensure you have all the necessary tools and technical knowledge required to perform this task.

BOOST CONTROLLERS

I’m experiencing excessive/fluctuating boost with the Boost Tee.

(The following answers also apply to Dual and Single Stage Boost Controllers)
• 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

How do I wire up the Single/Dual Stage Boost Controller?

The updated Fitting Instructions include a wiring guide. You can download them from the “INSTRUCTIONS” section of this website.


After installing the e-Boost2 my engine is over-boosting/underboosting.

• Check that the e-Boost solenoid is installed correctly.
• Ensure the factory boost control solenoid is not connected in the hose between the pressure source and the wastegate actuator
• Ensure the length of the wastegate actuator rod has not been modified, refer to the manufactures specifications.
• Check to see if the e-Boost solenoid is not blocked or contaminated with dirt, oil build-up or debris
• Check the joining hoses for splits, cracks or loose connections and ensure they are not blocked, kinked or restricted, particularly if the existing hose was reused
• Pressure test the wastegate actuator for leakage, the diaphragm or housing may be cracked or split
• Ensure the smooth and free operation of the waste gate arm in the turbo exhaust housing.
• Check that the hose between the e-Boost and the inlet manifold is not obstructed, broken or kinked.
• Check that the OBS is set higher than the boost pressure you are aiming for.
• Check the Blow-off Valve for leakage, some are used as over-boost valves
• Gate pressure maybe set too close to your actual boost pressure – ensure correct sensitivity setting.

I have a turbo diesel car with a vacuum activated wastegate. Can I control it with e-Boost2 or e-Boost Street?

• E-Boost will not work with vacuum operated wastegates.


I'm re-mounting my eBoost 2 and I don't want to lose the current setup. Will the settings be retained with the unit unplugged?

• No, you won’t loose anything, but if you are worried, take 5-10 minutes and note down all your settings. it’ll be helpful if you do accidentally change something.


What is the proper connection method for the e-Boost2 solenoid into an external wastegate?

• There is no “proper” way, just start with the basic hook up method as per the instructions and if you don’t get the desired effect, try the other hookup methods as outlined in the fitting instructions.

FUEL PRESSURE REGULATORS


Can I install a Fuel Pressure Regulator myself?

While a fuel pressure regulator can be fitted relatively easily, Turbosmart recommends its FPRs are fitted and tuned by a qualified technicians as an incorrect setting of fuel pressure may cause your engine to run lean with the potential for detonation.
Please Note: After fitting as FPR, Air-Fuel ratios must be checked.


How do I adjust the base pressure on the FPR?
Turning the screw clockwise will increase your base pressure and anti-clockwise will decrease base pressure. Ensure that when setting the base pressure the vacuum hose is disconnected and blocked and that the reference nipple is open to atmosphere.

BLOW-OFF AND BYPASS VALVES

I’ve installed a Supersonic BOV and now my engine is dipping below normal idle and stalling.

• Check the vacuum hose for splits, cracks, loose connection, kinking or any obstruction – old or fatigued hose may collapse under vacuum causing an obstruction
• With the engine running remove the vacuum/pressure hose from the nipple in the cap of the BOV, there should a loud hissing sound. The engine should idle poorly, double check by covering the end of the hose with your finger. If this does not occur, the hose could be blocked or crimped. Check the hose and replace if necessary.
• Ensure that the vacuum/pressure source is not shared and that the vacuum source is directly from the inlet manifold
• Check the seal between the adapter and the Race Port – ensure that there is no gap between the BOV base and the weld flange
• Check the join between the adapter and the intercooler pipe for leaking.


I’ve installed a Vee-Port in my car and despite all the tuning the car still stalls.

Some cars with sensitive Air Flow Meters will not respond well to atmospheric Blow-Off Valve. Turbosmart recommends fitting a bypass-type BOV like the Plumb Back. Fitting a bypass-type BOV will eliminate the stalling problem.


FUEL CUT DEFENDERS

The dials on my FCD2 do not go all the way around.

The adjustment dials do not turn 360O, they start at 1 and finish at 10. Do not force them past these points as this will damage your FCD2


I’ve accidentally zeroed all the dials, what are the factory settings on the FCD2?

Before setup the unit should be set to the following settings, Clamp=10, Release=10.


WASTEGATES

Will fitting an external Wastegate require any custom fabrication?

Yes, fitting an external wastegate will require fabrication of a custom manifold and or modification to an exhaust manifold.


Why is it important to check the Air-Fuel ratio while setting the desired boost pressure?

Any increase in boost pressure can cause the engine to run “LEAN”, resulting in possible engine damage.
