I am about to install and tune both my aem meth kit and aem ecu the shop asked me if i rather have it setup to come on threw the ecu, or using the progessive controller it comes with, i wasnt sure if it made any differance do yall have any input

 

I would use the ems just because that is one less system to fail and get in the way.

 

cool man thanks for the input

 

The shop was telling me they have set it up both ways i guess using the a signal from the ems to activate the meth system, and also using the controller whichs comes with the aem, the manger stated he prefers using the controller that came with the system because its a progressive controller and the nozzle pressure will increase as the boost increases, where when setup on the ems it basically just on when it gets the signal.
