AEM Water/Meth Injection control using AEM EMS instead of provided controller??
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.

The nitrous control options may work, but you probably can make it easier by using I/C(intercooler) spray options to kick on power to your water meth kit under those boost conditions. Or upgrade your water meth control unit to the new AEM one w/ a analog input as apposed to Vac/Boost.

Like Rudy said, You can use a LS output to a relay to switch the arm of the water meth. Not knowing too many specifics of the water/meth kit IDK if there is a delay from the time of arm till it actually starts spraying water. You will be best off if you have the 0-5v/MAF/Frequency controller. This way you can either tap your MAP sensor or add another one.
You can hook up the boost safe output wire from the water/meth controller to a SW input to the ECU. You can then set the ecu to allow for a higher boost target only if the water meth is working. If for whatever reason the controller stops working the ECU will keep the boost at a lower setting.
