AEM V3 Water/Methanol Injection Kit with Multi-Input Controller, No Tank - Part Number 30-3352

Racers with high compression naturally aspirated engines or boosted engines who are looking for an alternative to boost-dependent water/methanol injection controllers have a solution in AEM's Multi-Input WMI controller. The multiple input design 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 40 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 Multi-Input controller is offered in three kits; a one-gallon tank kit with a single injector for gas engines (PN 30-3350), a tank-less kit with a single injector (PN 30-3352), and a five-gallon tank kit with two injectors (PN 30-3351) for HD high-output gasoline applications. V2 Water/Methanol Nozzle and Controller Kit, Multi Input Controller - 0-5v/MAF Frequency or Voltage/Duty Cycle/Ext MAP, 200psi WM Pump, DOES NOT INCLUDE TANK

• Allows user to choose one of several signal inputs to control flow.
• No reservoir allows integration of custom of 3rd party reservoir.
• Optional wiring for W/M solenoid built into wiring harness
• V3 nozzle included, enhanced atomization of W/M mixture

The AEM V3 Water/Methanol Injection Kit with Multi-Input Controller provides flexible flow control for high-compression naturally aspirated engines and boosted applications. Designed for vehicles that need more than a boost-dependent water/methanol strategy, this tank-less kit allows integration with a custom or third-party reservoir while supporting multiple engine-management input signals.

The AEM Multi-Input controller can be configured for an external 0-5-volt MAP sensor, frequency-based Injector Duty Cycle, frequency-based Mass Airflow, or 0-5-volt MAF input. This flexibility makes the AEM 30-3352 suitable for naturally aspirated applications using MAF or IDC settings as well as ultra-high-boost vehicles operating above 40 PSI when paired with an appropriate external MAP sensor. The included 200 PSI pump and V3 nozzle help deliver consistent system operation and improved water/methanol mixture atomization.

The wiring harness includes provisions for an optional water/methanol solenoid, helping simplify custom installations and system integration. The kit does not include a reservoir, making it a practical choice for builders who already have a preferred tank or require a custom fluid-storage solution. Professional installation and proper calibration are recommended. This product is not emissions-certified for street use and is not approved for carbureted applications; verify applicable regulations before installation.

What's Included: Multi-Input controller, 200 PSI water/methanol pump, V3 injection nozzle, wiring harness, and related installation hardware. Reservoir is not included.

Features:

• Multi-input control: Supports 0-5-volt MAP, frequency-based Injector Duty Cycle, frequency-based MAF, and 0-5-volt MAF signals.
• Tank-less configuration: Allows integration of a custom or third-party reservoir for flexible installation.
• High-pressure operation: Includes a 200 PSI water/methanol pump for consistent fluid delivery.
• Enhanced atomization: The included V3 nozzle improves dispersion of the water/methanol mixture, while the harness provides wiring provisions for an optional solenoid.
