I bought the AEM Water/Meth Injection kit because I had the AEM EMS and figured why not keep it in the same family. Problem is I wanted to start spraying at 17psi up to 23psi. I really only wanted AI being sprayed for a high boost setting so I can have a low boost everyday setting that doesn't use any windshield washer fluid at all. The AI is really a safety to be able to run upwards of 20psi on 93 octane.

Problem is the AEM controller's highest beginning setting is 11psi. I really don't want water spraying anywhere near that early and was wondering if anyone has any idea how to bypass this and get it to start up later using AEM EMS. I've read up on using another relay to cut power to the controller completely and using nitrous tables. Any ideas are appreciated, thanks.

 

No suggestions from anyone??

 

Boost activated digital output on ecu, if the AEM can't take a digital input (low current hi/low signal), use the ecu output to drive a relay.

 

Thanks Slides, I'll look into it.
