And Posted July 8, 2021 Report Share Posted July 8, 2021 Hi I have a g4+ fury that I'm trying to setup on my car, I'm having an issue with the Aux outputs 5 to 8 where they are only showing 7.8V. The ecu is showing that the input voltage is >12V and the internal voltage levels are all very close the what they should be. My DBW throttle is working fine as well as the other sensors on the 5v etc. I seem to be able to trigger the injectors and also the coils. Anyone got any suggestions? thanks Andy Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 8, 2021 Report Share Posted July 8, 2021 What are you trying to drive with them? Are you wanting to highside drive or lowside drive? Quote Link to comment Share on other sites More sharing options...
And Posted July 9, 2021 Author Report Share Posted July 9, 2021 For the Aux ones I'm trying to drive 3 lights on the dash and the other issue I have is I'm trying to drive 3 relays one from ign drive 5 and 2 from injector drive 7 and 8 which is showing the 7.8 volts on the relay triggers. thanks Andy Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 9, 2021 Report Share Posted July 9, 2021 Ign drives are only pulled up to about 6V, Injector drives arent pulled up at all, any voltage measurement will just show what is present on the other side of the relay coil so not really relevant, both of these should show near 0V when "on". For the lamps, how are they wired, and how is the aux set up? Quote Link to comment Share on other sites More sharing options...
And Posted July 9, 2021 Author Report Share Posted July 9, 2021 Hi Adam Thanks for the quick reply they are directly out of the ecu through the lamp and then to ground. thanks Andy Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 9, 2021 Report Share Posted July 9, 2021 So you have the aux set to highside drive right? Quote Link to comment Share on other sites More sharing options...
And Posted July 9, 2021 Author Report Share Posted July 9, 2021 yes that is correct Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 9, 2021 Report Share Posted July 9, 2021 Still not quite sure I understand the problem. Are the lamps too dim or something ? What is the resistance of the bulb? Can you attach a copy of the tune too. Quote Link to comment Share on other sites More sharing options...
