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 internal MAP
sensor. In other words, more boost equals more fluid. It is therefore imperative that the
vacuum/pressure 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 manifold (boost) pressure minimum
fluid injection starts and at what pressure maximum/full fluid injection occurs. Fluid injection will
‘progressively’ increase between these two points as set by the adjustment knobs.
The
“Start PSI” dial has a range from 1 psig (full counterclockwise rotation) to 11 psig (full
clockwise rotation). The “Full PSI” dial has a range of 5 psig (full counterclockwise rotation) to
35 psig (full clockwise rotation). It is suggested to adjust the
“Start PSI” value by setting the dial
to approximately 25% of the vehicles maximum boost. Adjust the full-in value to your maximum
possible boost. These are only suggestions; improper use or setting could result in engine or
vehicle damage -- please consult your tuner.
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.
