AEM Electronics 30-3304 Water/Methanol Injection Controller Kit V3 (Internal 35psi MAP) – Performance Optimization for Turbocharged 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 precise injection of a water/methanol mixture, allowing safe power increases in high-performance setups.

Features

• Internal 35 psi MAP sensor — Boost-based control without additional external sensors.
• Boost Safe 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 — Precisely set start point and maximum injection point, even with gloves on.
• Simplified installation — Color-coded wiring and positive-lock connectors prevent installation 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 protection layer budget alternatives lack: in case of failure or low fluid level, it automatically disables boost, preventing knock under extreme conditions. The linear flow strategy ensures proportional delivery based on actual engine demand, guaranteeing reliability in high-level competition and daily use.

FAQ

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

What happens if the tank runs dry?
The level sensor detects low fluid and activates Boost Safe to protect the engine from detonation damage.

Is installation complicated?
Color-coded wiring and detailed manual make installation straightforward for professionals and advanced enthusiasts alike.
