The on-demand progressive Multi-Input Controller in AEM’s #30-3350 Water/Methanol Injection kit for petrol & diesel vehicles 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.
AEM’s engineers spent extensive time developing 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.
The new controller design features 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 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. The controller housing features an easy to access integrated fuse and moulded mounting tabs.
AEM’s Multi-Input Water/Methanol Injection kit’s wiring harness is terminated with a positive-lock connector on one end and has colour-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.
FOR OPTIMUM RESULTS, ALL WATER/METHANOL INJECTION SYSTEMS AND GAUGES SHOULD BE RUN WITH AN AEM INLINE FILTER (AEM PART #30-3003)
