kool021 Posted December 15, 2018 Report Share Posted December 15, 2018 Can we connect GFB boost controller to G4+ ecu if so how can we do it? Quote Link to comment Share on other sites More sharing options...
neil brown Posted December 15, 2018 Report Share Posted December 15, 2018 Why not let the ecu control the boost as in boost tables and control section Quote Link to comment Share on other sites More sharing options...
kool021 Posted December 15, 2018 Author Report Share Posted December 15, 2018 Well my ecu is not connected to boost solenoid my GFB is so how would G4 control boost? Quote Link to comment Share on other sites More sharing options...
neil brown Posted December 15, 2018 Report Share Posted December 15, 2018 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 Quote Link to comment Share on other sites More sharing options...
kool021 Posted December 15, 2018 Author Report Share Posted December 15, 2018 I prefer connecting boost controller to ecu if it can be done I already connected knock oil air tem wide bend.. I prefer to do that. Quote Link to comment Share on other sites More sharing options...
neil brown Posted December 15, 2018 Report Share Posted December 15, 2018 Will let tech team answe your query me personally I let the ecu control the boost like what I have done What ecu are you running ? Quote Link to comment Share on other sites More sharing options...
Richard Hill Posted December 15, 2018 Report Share Posted December 15, 2018 As Neil mentioned, probably better in the long run to let the ECU control the boost valve on an aux out. What ECU are you running and what engine ? Quote Link to comment Share on other sites More sharing options...
Shedley Posted December 15, 2018 Report Share Posted December 15, 2018 I would connect the solenoid to the ecu as well, you have much more advanced control like that Quote Link to comment Share on other sites More sharing options...
kool021 Posted December 16, 2018 Author Report Share Posted December 16, 2018 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 Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 16, 2018 Report Share Posted December 16, 2018 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. Quote Link to comment Share on other sites More sharing options...

kool021 Posted December 22, 2018 Author Report Share Posted December 22, 2018 Ok So better off connecting ecu to link solenoid and removing boost controller completely? Using XSL loom how to we connect it? Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 23, 2018 Report Share Posted December 23, 2018 What model plug-in ECU do you have? Quote Link to comment Share on other sites More sharing options...

All of them have different wiring and different functions available on the expansion connectors. Quote Link to comment Share on other sites More sharing options...
kool021 Posted December 23, 2018 Author Report Share Posted December 23, 2018 Skyline r33 series 2 was RB25DE before and now RB25/30DET Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 23, 2018 Report Share Posted December 23, 2018 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. Quote Link to comment Share on other sites More sharing options...

Link help specifies adding a flyback diode for output protection on non aux outs , is this the case for ignition drives too? Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...

Did you end up running the GFB boost controller? I’d like to run one when I get my link installed and car running. Quote Link to comment Share on other sites More sharing options...
