AEM V1. Activate my Meth pump?
 

Right now I have a boost pressure switch that will turn my pump on. I want to be able to turn my pump on with the AEM to get rid of possible pressure switch, wiring, relay failure. The es there is, the less there is to go wrong. How would I do this?

Also I have a solenoid inline after the pump to keep vacuum from drawing fluid through the lines. I would need to activate this as well.

If you just want it to be off or on, that's easy just pick one of the available switches than go and configure the parameters when that switch will activate (i.e. rpm, load, coolant temp). All your really doing is skipping the pressure switch and use any available switch to trip the pump.

However, i would highly recommend progressive controller if you are running a lot of meth. Another thing to keep in mind if you inject around 2000cc of meth and hit fuel cut you will lose the motor in a snap.
