The on-demand progressive Multi-Input controller in AEM’s PN 30-3350 Water/Methanol Injection kit for gasoline 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.

THE AEM WATER/METHANOL INJECTION SYSTEM ADVANTAGE
Water/methanol injection for gas engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation on high compression naturally aspirated (NA) race engines. This allows racers to reliably increase boost and advance ignition timing—without using high-octane racing fuel—for improved power gains. AEM’s Water/Methanol Injection Systems utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol system.
AEM’s Multi Input controller design enables users to install Water/Methanol Injection on high compression naturally aspirated vehicles (NA) via the MAF/IDC settings. 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 Multi-Input Controller is available with a 1.15-gallon tank (PN 30-3350), five-gallon tank (PN 30-3351) and in a tank-less kit (PN30-3352).

Robust, Easy to Use Controller Design
The Multi Input Kit PN 30-3350 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, an easy-to-access integrated fuse and molded mounting tabs. Programming the Multi-Input controller for MAF, external MAP or IDC is easy; it has a plug covering the programming dipswitches and a programming legend on the back for the 0-5v and frequency based settings.
Innovative Injector Design Delivers Faster Cooling with Less Fluid Used
In testing at AEM, the new V3 250cc WMI nozzle and the V2 250cc WMI nozzle both achieved a 90-degree inlet temp reduction; however, the V3 nozzle design achieved this reduction nearly 6.5 seconds faster. Consider that on an average sportsman drag car this can represent close to 40% of track time. On a road race car, applying more timing 6.5 seconds faster can mean a critical time to pass on a corner exit.
We then tested a V3 250cc injector against a V2 500cc injector to see if the larger V2 injector would improve cooling speed. The V2 500cc injector achieved nearly identical cooling speed as the V3 250cc injector, but it required almost 44% more fluid to achieve the same cooling. Less fluid used means fewer refills of your WMI tank and less money spent refilling it. Using the V2 500cc nozzle with a one-gallon tank, you will get close to 7 minutes and 50 seconds of run time at full pressure. Using the V3 250cc nozzle with a one-gallon tank, you will get 13 minutes and 30 seconds of run time at full pressure.
Heavy-Duty Waterproof High Pressure Injection Pump – Safe for Engine Bay/Frame Rail Mounting
AEM’s internally-bypassed water/methanol injection pump is waterproof and safe for mounting in loactions that are exposed the elements. It does not cycle on and off and provides quiet, smooth operation. It features robust construction including integral hose fittings, EPDM seals and a Santoprene diaphragm that provides consistent and reliable fluid delivery.
Low-Profile 1.15 Gallon Tank
AEM’s gas Water/Methanol Injection Systems are available with or without a compact 1.15 gallon tank that features an anti-starvation reservoir. 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.
AEM’s Water/Methanol Injection kit’s wiring harness 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.
Integrated Boost Safe Feature
The controllers in AEM’s Water Methanol systems include an integrated “Boost Safe” output feature that monitors the entire injection system and triggers a ground signal via an output if it detects a voltage-related error (short, bad connection, broken wire, overheated pump, high or low voltage signal, etc.), 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. Combined with the integral and highly accurate conductive low-fluid switch in the tank, “Boost Safe” can also put your engine in safe mode before the system runs dry. This exclusive feature is found only on AEM Water/Methanol Injection Systems.
Revised Flow Control Strategy for More Linear Fluid Delivery
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.

Important Safety Notice Regarding Methanol
AEM strongly recommends that users never exceed a 50% methanol concentration when using any AEM Water Methanol system or component.
All AEM Water/Methanol injection systems and components (pump, lines, fittings, filter, flow sensor, tank, and nozzles) are 100% chemically compatible with methanol. However, for safety reasons we strongly recommend that users never use more than a 50% methanol concentration in our systems.
Methanol is a toxic and highly flammable chemical. 100% Methanol ignites easily and burns vigorously with an almost undetectable flame. Methanol can be absorbed through the skin and even small amounts can cause blindness or even death. Using this fluid at high pressures, without dilution, in an under-hood environment with nylon lines and push-to-connect fittings is very unsafe. The performance advantages of using greater than 50% methanol concentrations are small, if they exist at all. However, the safety issues are very real and far outweigh any perceived benefit of running high concentrations of methanol.
