SidewayzSkyvia Posted January 1 Report Share Posted January 1 Ok so I'm putting an rb25det s1 into a 2009 Impreza using a wrx11x plug in ecu. I've made the loom, trying to set up the map so everything works right. As it's an Impreza the wiring is a bit different than a wrx/sti. So I've had to move some stuff around. I'm trying to use aux 3 to control the vtc solenoid. But aux 3 is locked in software. I'm just curious if there is a way to unlock this so I can use it or would I need to use a different output? I'm building off the wrx11x sample/base map and I'm not currently connected to the ecu if that matters. Thanks for any and all help Quote Link to comment Share on other sites More sharing options...
Vaughan Posted January 1 Report Share Posted January 1 go to the function using Aux 3 and change it there, double clicking on the locked Aux 3 Function setting will take you straight to it or go into the vvt settings menu. Quote Link to comment Share on other sites More sharing options...
SidewayzSkyvia Posted January 1 Author Report Share Posted January 1 I've tried disabling the aux 3 vvt functions that come in the wrx11 map. Turned off vvt. Aux 3 remains locked. On my old g4+ I was able to just double click the aux channel and assign cam-switched and set the switch conditions. But i can't seem to do this on the new g4x software.

Adamw Posted January 2 Report Share Posted January 2 As Vaughan suggested, you now set up the aux inside the function settings not inside the pin settings. There is no longer a Cam-switched function, this is done as a GP Output. So, go to VVT>Exhaust Bank 2, set PWM output to none. Then go to >Auxiliary Outputs>GP Output*, set the output to Aux 3, set the conditions for the switched cam. Quote Link to comment Share on other sites More sharing options...
SidewayzSkyvia Posted January 2 Author Report Share Posted January 2 Ok awesome. That would make sense why I couldn't find that option anywhere. I'm still learning the g4x software after so many years of using a G4+. One more similar question. I also have my boost control solenoid wired to aux 14(purge solenoid pin) as this chassis doesn't have wiring in the bulkhead loom for it. Would I be able to use this method to use aux 14 to control the boost control solenoid or would it be a better idea to swap pins at the ecu connectors? Thanks again for all your help Quote Link to comment Share on other sites More sharing options...
SidewayzSkyvia Posted January 2 Author Report Share Posted January 2 Just looked at the ecu Pinout again. Aux 3 and aux 14 are right next to each other so I'll switch the pins. It seems like I can't use aux 14 to boost control. But it looks like it should work to control the vtc solenoid. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted January 2 Report Share Posted January 2 Only Aux 1-10 (and spare Ign and Inj pins) can do PWM, Aux 11-16 are switched only and you need PWM for Boost control. Quote Link to comment Share on other sites More sharing options...
