AEM Electronics 30-3304 Water/Methanol Injection Controller Kit V3 (Internal MAP 35psi) – Performance Optimization for Turbo Gasoline Engines

The AEM Electronics 30-3304 is a third-generation water/methanol injection controller designed for turbocharged or supercharged gasoline engines. This system reduces intake air temperatures and controls detonation through the precise injection of a water and methanol mixture, allowing power to be safely increased in high-performance configurations.

Key features

• Internal 35 psi MAP sensor — Boost-pressure-based control with no need for additional external sensors.
• "Boost Safe" safety system — Automatically disables boost or alerts the driver in case of system failure or low fluid level, protecting the engine from detonation damage.
• Linear flow strategy — Progressive mixture delivery based on actual engine demand, improving efficiency and response.
• Large adjustment dials — Allow precise configuration of the start point and the maximum injection point, even with gloves on.
• Simplified installation — Color-coded wiring and positive-locking connectors to prevent mounting errors.

Why choose the AEM V3

Unlike basic controllers, the AEM 30-3304 uses a high-precision internal MAP sensor that eliminates injection lag. The Boost Safe system adds a layer of protection that budget alternatives do not offer: in case of failure or low fluid level, it automatically disables boost, preventing knocking under extreme conditions. The linear flow strategy ensures a proportional delivery based on actual engine demand, guaranteeing reliability in high-level competition and daily use.

Frequently asked questions

Do I need an external MAP sensor?
No, the 30-3304 model includes an internal MAP sensor capable of reading up to 35 psi of pressure.

What happens if the fluid in the tank runs out?
The level sensor detects the lack of fluid and activates the Boost Safe system to protect the engine from detonation damage.

Is installation complicated?
The color-coded wiring and detailed manual ease installation for both professionals and advanced enthusiasts.
