6. TROUBLESHOOTING
The following points should be checked if you find that your engine is over-boosting, under-boosting or the boost pressure is fluctuating
erratically. Please note the following checks will cure 99% of problems experienced when fitting a Turbosmart e-Boost.
-
Check that the e-Boost solenoid is installed correctly, refer to section 2c. for detail
- 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 wastegate 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, refer to section 4a for more detail
- 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, refer to section 4e
