The Multi-Input water/methanol injection controller from AEM features a design with multiple inputs that enables installation on both naturally aspirated vehicles (NA) with high compression via the MAF/IDC settings and ultra-high boost vehicles (above 35 PSI) using an external MAP sensor.
It works with an external 0-5 volt voltage-based MAP sensor, a frequency-based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5 voltage-based MAF.
The design includes large, turn-resistant knobs and larger numbering to set accurate start and full activation points easily, with covered status LED and test buttons for added splash resistance.
Integrated into the controller housing is a plug for mating to the redesigned wiring harness's positive-lock connector.
The controller has an easy-to-remove plug covering the programming dipswitches and a programming legend on the back for the 0-5 volt and frequency-based settings.
The housing features an integrated fuse that is easy to access and molded mounting tabs.
AEM's engineers spent extensive time developing the flow control strategy of the controller 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 on gasoline engines or EGT reduction on turbo Diesels.
The wiring harness for the Multi-Input controller from AEM is terminated with a positive-lock connector on one end and has color-coded wires to ease installation.
Both the power and ground wires for the pump are 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.
