I would wire the boost safe output from the controller to a spare DI input on the ecu. I would also set up a relay to power the system via the ARM + via a relay controlled by the link as well. Then you can use a combination of an arming switch in the cabin plus logic from the link before the system would be active. Quote Link to comment Share on other sites More sharing options...
DerekAE86 Posted August 30, 2023 Report Share Posted August 30, 2023 Have you purchased the AEM injection kit already? Because unless you want the physical buttons on the controller to change your settings - all the functions of that unit could be controlled directly by the ECU.

Yes I have the whole kit with the controller. How do I set it up to the ecu to control the kit? 17 hours ago, DerekAE86 said: Have you purchased the AEM injection kit already?

Is there a simpler way to let the ECU control when the methanol start doing its work. Quote Link to comment Share on other sites More sharing options...
