Adamw Posted March 14, 2022 Report Share Posted March 14, 2022 One side of the switch goes to a DI, the other side can go to ground, 5V or 12V, whatever is most convenient. Quote Link to comment Share on other sites More sharing options...

Adamw Posted March 14, 2022 Report Share Posted March 14, 2022 Yes. You will need to set up the multiple boost tables etc, but the tuner will need to do that. Quote Link to comment Share on other sites More sharing options...

Adamw Posted March 16, 2022 Report Share Posted March 16, 2022 You will need another expansion loom. Or if you no longer use the auto/manual intercooler spray switch you could use one of those DI's for your boost switch. Quote Link to comment Share on other sites More sharing options...

Have the spray icon illuminated on the dash when high boost is activated as well Quote Link to comment Share on other sites More sharing options...

Adamw Posted March 17, 2022 Report Share Posted March 17, 2022 The IC spray function is not set up in our base map as the set up is different depending on if the ecu is fitted to an Evo 4/5/6/7/8. If you write how you want the switch to work I can help you set it up. Quote Link to comment Share on other sites More sharing options...
