I use the AEM controller at it's lowest settings, it doesn't start injecting until the boost goes over 11psi and wouldn't be at a 100% until the boost would reach 36psi. As I only run my boost at 20psi at maximum at the moment, the water meth duty cycle never goes over 36% Sent from my SM-G935F using Tapatalk
Hi,
You should probably use a smaller nozzle so you can run the pump at near 100% duty to improve spray atomisation.
One of the downsides of adjusting pump speed to set flow is that what you are actually changing is pressure and therefor spray atomisation.
So if you have a big nozzle and low duty you will have quite big droplets.
Another big downside of AEM:s MAP based system is that you will get the same amount of water at 3500rpm and 7000rpm if boost is constant so you would be moving twice the amount of air but same amount of water.
I started with the same AEM controller as you but threw it in the bin, and controlled the duty in my ECU instead. However AEM also have a MAF based controller that probably is better on oem ECU.
Here is a good summery of different WMI systems with pros and cons: http://procedetuning...ed-3/index.html
