The Hondata 4 port boost controller precisely directs pressure to the top and bottom of your waste-gate diaphragm. It allows much lower waste-gate spring pressure for better low gear boost control and perfect high gear, high boost control.
For use with:
The Hondata 4 port boost control solenoid is designed for use in high boost applications, but also works well in low boost applications. It is normally closed so that on failure you will run off the waste-gate spring to prevent over-boosting. It uses 1/8th NPT fittings which can be adapted to AN fittings.
If you are upgrading from a 3 port solenoid, the boost control tables will need re-tuning.
If you are running an OBDI ECU, you will need to purchase the Components Kit to make the Solenoid operable with your application
