Hondata 4 Port Boost Control Solenoid

Hondata 4 Port Boost Control Solenoid 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. A 10 lb wastegate spring will enable 50+ psi of boost Better spool-up and mid range power Better duty cycle control For use with: Hondata S300 Hondata K-Pro Hondata FlashPro 2006-11 Honda Civic Si Hondata FlashPro Honda S2000 Hondata FlashPro 2004-008 Acura TSX 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 Boost Control Solenoid, the boost control tables will need re-tuning (and we can help).
