Turning on Meth with AEM EMS?

[stealthystu]

I want my meth to turn on when I exceed XX psi of boost. What I was hoping to do was connect my EMS to the control unit of the meth and after the load exceeds XX psi the EMS would send out a +12V signal. That signal would turn on the control unit for the meth, and soon after, the trigger point on the meth controller would be met with a certain load (XX psi + Y psi) and start the meth injection.

Will this work? Can the EMS send out a 12V signal? What's a better way to turn it on? I don't want any extra switches that I could forget to turn on or off. Right now, my AEM Truboost has a built in switch for changing my boost setting. I want that to be the only switch I need to turn the meth on or off.

Most of the meth kits come with a boost solenoid that you can set to your desired psi to inject.

you can do that easily with the NOS switch. The nos map will also allow you to make fueling changes for when the meth is on. That way you can run the car with the meth on or off easily.

I can't believe how stupid I am sometimes. I basically said I would have it start on it's own at some boost level but thought for some reason I still needed the EMS to do something to turn it on. Thanks

You still might want to run it thru the aem for additional tweaking. Sometimes meth injection can throw off desired fuel delivery and timing values, which are easily adjusted thru the nitrous maps, like mentioned above.
