Controller
Settings
The AEM Water Methanol Injection Controller is a progressive type controller. This means that
fluid will be injected in proportion to the amount of boost that is detected by the external MAP
input. In other words, higher signal input equals more fluid. It is therefore imperative that the
external signal connection be made properly and securely or vehicle/engine damage could
occur. In addition, the controller will automatically compensate for any fluctuations in battery
voltage variations to ensure consistent flow under all conditions.
The two knobs on the face of the controller dictate at what signal input minimum fluid injection
starts and at what signal input maximum/full fluid injection occurs. Fluid injection will
‘progressively’ increase between these two points as set by the adjustment knobs.
The
“Start” dial has a range from 0% (full counterclockwise rotation) to 100% (full clockwise
rotation). The “Full” dial has a range of 0% (full counterclockwise rotation) to 100% (full
clockwise rotation). It is suggested to adjust the
“Start” value by setting the dial to
approximately 25% of the vehicles maximum signal input. Adjust the full-in value to your
maximum possible percent for signal input. These are only suggestions; improper use or setting
could result in engine or vehicle damage -- please consult your tuner.
Mode Selection
The mode can only be selected or changed while the unit is turned off. To change the mode
remove the back cover exposing the three DIP switch selectors. Follow the guide on the
controller to select the appropriate mode for your application.
Status LED
The controller has an on-board Status LED. This will mimic the operation of the external LED.
Upon startup the current mode is flashed in green on the status LED. It will flash error codes in
red as well as illuminate with varying intensity as a function of flow in green.
