AEWON Posted April 7, 2020 Report Share Posted April 7, 2020 Hi guys, been scouting the forums and just need a technical question clarified, I see there’s conflicting info on high side driving on some of the plug in ECU’s. I had intended on using Ign 5 to Ign 7 on my S13 plug in link to 12v + switch some relays as the bussmann Relay box I have needs a positive trigger. If these can’t be used, are there any outputs on this particular plug in board I could use? I no longer have A/C, it’s been converted to E-Throttle, so I have quite a few more Auxilary’s free.

Vaughan Posted April 8, 2020 Report Share Posted April 8, 2020 Aux 5-8 can drive high side, ignition drives can only drive low side when being used as an auxiliary. In PCLink set the Driver Type to High Side. On the S13 plugin: Aux 5 is pin 113 Aux 6 is pin 25 Aux 7 is pin 32 Aux 8 is pin 33 Quote Link to comment Share on other sites More sharing options...

Can I use any Auxiliary Outputs to "positive " trigger a 12v relay? Cheers Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 8, 2020 Report Share Posted April 8, 2020 Driving high side means outputting 12v so you can use any of Aux5-8 to send 12v to a relay which has a ground on the other side of a coil to activate it. Quote Link to comment Share on other sites More sharing options...
AEWON Posted April 8, 2020 Author Report Share Posted April 8, 2020 Perfect, I had read somewhere on this forum that this was only available on the Wire in ECU not the Plugins, hence my question. Thanks for your reply! Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 8, 2020 Report Share Posted April 8, 2020 The help does only specify storm, xtreme and fury but I believe the plugins have the same hardware. The section of the help manual is Wiring Information -> Output Wiring -> Auxiliary Output Wiring -> High Side Driving There is more help information under G4+ Tuning Functions -> Auxiliary Outputs -> Wiring Auxiliary Outputs as well Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 8, 2020 Report Share Posted April 8, 2020 Sorry for the confusion Aewon, Vaughan isnt quite right here. Most of the Plug-ins dont have highside drive hardware on board (the only exception is some of the subarus and hondas). The auxes do have a 1.5Kohm pull-up to 12V, so they will drive to 12V when "off", but they wont have enough grunt to drive a relay. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted April 8, 2020 Report Share Posted April 8, 2020 Apologies if I got that wrong, I did test it with a relay I had lying around and it seemed to work but it was done on a G4X plugin not a G4+ Quote Link to comment Share on other sites More sharing options...
