Message	the wastegate spring pressure, the wastegate opens. The boost solenoid uses the pulse width signal from the BC or ECU to determine its duty cycle to stay open. Since MBC does not send out any signal, the solenoids stay either fully closed or fully open depends which type. So they are totally irrelevant with MBC. www.ztechz.net ICQ # 14337317
Follow Ups	Anyone actually running safety boost solenoids with a MBC? - nomoco 10:45:10 09/11/09 MBC does not belong on a TT Z. (n/m) - John@Z1 11:05:24 09/11/09 It depends on the turbos.

(n/m) - inf 23:22:35 09/12/09 it has to do with the way the boost controller modulates the - Machtavian 19:49:36 09/13/09 How else would you the MBC work? It needs the stock solenoid - Bernie (NoVA) 11:18:29 09/11/09 huh? - Antihero 11:47:01 09/11/09 ??? (n/m) - TTFairladyZ 11:48:31 09/11/09 Boost jets require the stock solenoid, MBC's don't.
