GFB boost controller

Recommended Posts

The ecu would be connected to the boost solenoid vis a 12+ switched supply and the -ve would be connect to an aux output and ecu would be configured to operate that output as boost soleniod

 

best speak to your mapper to set it up

RB25/30 vct full forge I’ll just wait for link  technician to reply But I think those 2 wires connect to ecu xsl loom and ecu use the boost controller to get information from solenoid. Use it as sensor not sure yet tho

I dont see it being of much use to connect the ECU to the blue wire.  The note on your attached instruction says "For ideas on ways to use the trigger wire see page 14", so you should probably start by reading that to see if any of it sounds useful to you but personally I agree with the others here, letting the ECU control boost gives you much more flexibility - boost by gear, etc.

What model plug-in ECU do you have?

I mean what model car is the plug-in for.  WRX? Evo? Honda?  All of them have different wiring and different functions available on the expansion connectors.

Then Ign 7 or 8 would be the easiest.  1 wire from the solenoid goes to a switched +12V supply, the other wire goes to the expansion connector, ign 7 or 8.

Link help specifies adding a flyback diode for output protection on non aux outs , is this the case for ignition drives too?

I believe your typical ~5W, 30Hz boost valve is ok without flyback, some of our plug-ins such as evo8 have them connected to Ign drives with nothing else added.  For idle solenoids you will need a flyback diode.
