Guys,

I am going to be upgrading my fuel system to twin pumps and purchase a relay and wanted to fire it with the aem, what pin did you use when you set it up? How do you configure it in the software?

Thank you,

Justin

 

What I do is find an available low side output and wire in the relay to trigger the pump from the associated pin. Then within AEMPro output options for whatever low side you choose set a PSI based trigger, which I typically use about 10-12psi for larger turbo cars. You can then test this works by setting the psi trigger to -14psi while the car is off and key is on. Cycle it back and forth making sure it turns on and off correctly. You may also want to add a channel to show whenever that LS is triggered in your logs.

You will need to tune the area where the pump kicks on to remove the rich spot but this is very simple to do.

 

Help on this too
