AEM V2 Multi Input Controller Kit - 0-5v/MAF Freq or V/Duty Cycle/MAP

AEM V2 Multi Input Water/Methanol Controller Kit | 0-5V, MAP, MAF & IDC

Upgrade your water/methanol setup with the AEM V2 Multi Input Controller Kit. Universal compatibility with 0-5V MAP, MAF frequency/voltage, and Injector Duty Cycle.

The AEM V2 Multi Input Water/Methanol Injection Controller Kit provides precise, progressive fluid delivery tailored to your engine's real-time performance needs. Unlike standard boost-dependent controllers that rely solely on manifold pressure, this multi-input controller accepts a wide variety of engine signals—including 0-5V voltage signals, frequency- or voltage-based Mass Air Flow (MAF) inputs, external MAP sensors, and Injector Duty Cycle (IDC) signals.

Equipped with an updated, progressive flow-control algorithm, the V2 controller delivers a linear fluid output that closely mirrors actual air/fuel requirements. The enclosure features large, turn-resistant adjustment dials for setting start and full activation points, integrated splash-resistant status LEDs, and a built-in "Boost Safe" fail-safe system that alerts you or cuts boost if a short, low fluid level, or wiring error occurs.

Best Uses

1. Naturally Aspirated & Supercharged Applications: Ideal for high-compression engines or supercharged setups where traditional manifold boost reference is unavailable or inaccurate.
2. High-Boost Forced Induction (Turbo/Supercharged): Suits high-horsepower builds requiring precise water/methanol flow mapped to exact airflow (MAF) or fuel demand (IDC).
3. Custom & Standalone ECU Tuning: Perfect for race vehicles using aftermarket 0-5V external MAP sensors or custom signal outputs.
4. Detonation Suppression & Charge Cooling: Designed for drivers seeking to safely run higher boost levels or advanced ignition timing without relying exclusively on expensive race fuels.

Features

1. Multi-Signal Compatibility: Supports 0-5V voltage inputs, frequency- or voltage-based MAF signals, external MAP inputs, and Injector Duty Cycle (IDC) inputs.
2. Progressive Linear Flow Strategy: Features an updated injection strategy that scales fluid volume smoothly relative to engine load signals.
3. Integrated "Boost Safe" Failsafe: Built-in circuit monitors system voltage, continuity, and fluid levels to trigger a protective ground output signal if an anomaly occurs.
4. Ergonomic & Weather-Resistant Housing: Includes turn-resistant adjustment dials, covered status LED/test buttons, easy-access fuse panel, and mounting tabs.
5. Simplified Wiring Harness: Plug-and-play style harness with positive-lock connectors and isolated power/ground paths to prevent accidental pump triggering.

Benefits

1. Universal Tuning Flexibility: Seamlessly integrates across diverse vehicle platforms without requiring a specific engine management system.
2. Engine Protection: Suppresses harmful detonation and lowers intake air temperatures (IATs), safeguarding high-output engines under heavy load.
3. Increased Power Potential: Enables safe advancement of ignition timing and higher boost levels on standard pump gas, achieving up to 20% power gains.
4. Failsafe Peace of Mind: Protects your engine against system shorts, pump failure, broken wiring, or fluid exhaustion before damage occurs.
5. Easy Setup & Adjustment: Intuitive internal DIP-switch configuration and simple dial adjustments allow quick on-the-fly calibration.
