Starting the Engine
(1) Inspect the installation. Reconnect the negative terminal of the battery and start the engine.
(2) Check and make sure that there no air leeks, clearance problems or irregular sound.
(3) Lightly rev up the engine couple times to check if the blow off valve is operating.
Adjustment after installation
If irregular idle or engine stall occurs, loosen the M6 lock nut and turn the adjustment screw to HARD until the problem is eliminated.
After the adjustment, tighten the lock nut to secure the setting.
- The adjustment is preset to the softest position form factory. Do not turn it further out that this position.
- Make sure to loosen the lock nut before making adjustment. Turning the adjusting screw without loosening the lock nut will strip out the top housing.
- When the adjustment screw is turned in, the stock of the valve decreases. Screwing it in too far will affect the proper operation of the valve.
When venting the outlet to the atmosphere, depending on the application, the airflow meter voltage can drop enough to stall the vehicle when the blow off valve is discharged. If adjustment of the top screw cannot prevent the engine stall, install e-Manage system and use the Anti Engine Stall feature or reroute the discharge outlet back into the intake system after the airflow meter.
