About the manufacturer

The new controller designs feature large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. A plug is integrated into the controller housing for mating to the redesigned wiring harness's positive-lock connector. The Boost Dependent controller housing has a molded-in, barbed nipple to accept a boost hose and a wiring legend on the back. The Multi Input controller has an easy-to-remove plug covering the programming dipswitches and a programming legend on the back for the 0-5v and frequency based settings. Both controller housings feature an easy to access integrated fuse and molded mounting tabs.

The second controller (Kit PN 30-3350) features a multiple input design that enables users to install AEM's Water/Methanol Injection Kit on both high compression naturally aspirated vehicles (NA) via the MAF/IDC settings and ultra-high boost vehicles (above 35 PSI) using an external MAP sensor. The Multi Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF.

The new wiring harness is terminated with a positive-lock connector on one end and has color-coded wires to ease installation. An integrated Pump Ground circuit is included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive.

These new controllers retain the "Boost Safe" injection failsafe system, which is an output that will activate if there is a short, loss of continuity or high or low voltage or low fluid condition, allowing users to define their failsafe strategy from something as simple as flashing a warning light to more advanced strategies like pulling boost or ignition, or switching fuel maps on a standalone engine management system.

AEM's engineers spent extensive time revamping the controller's flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engine's need for water/methanol injection, which further optimizes charge air cooling and detonation control. Three resized injector nozzles are in each kit and allow for improved flow capability (a flow graph is available on our website).

A more accurate, conductive low level fluid sensor is integrated into the tank and features a positive lock connector with color-matched wires to the wiring harness. The sensor eliminates any chance of incorrect readings due to interference from debris.

One is boost dependent (Kit PN 30-3300) for forced induction vehicles up to 35 PSI of boost. The Boost Dependent controller has an on-board manifold absolute pressure (MAP) sensor with a molded-in nipple for a boost hose pickup.
