AEM V2 HD Controller Kit - Internal MAP w/ 40psi Max

AEM V2 HD Water/Methanol Controller Kit | 40 PSI Internal MAP (PN 30-3306)

Upgrade your boost-dependent injection setup with the AEM V2 HD Water/Methanol Controller Kit (30-3306). Features internal 40 PSI MAP sensor, progressive control & easy wiring.

The AEM V2 HD Water/Methanol Controller Kit (Part # 30-3306) is a progressive injection controller designed for forced induction applications, high-boost gasoline engines, and heavy-duty diesel builds.

Engineered with an internal MAP sensor rated up to 40 PSI Max, this controller reads manifold pressure directly via a integrated barb fitting, eliminating the need for an external pressure sensor. The progressive design allows for fine-tuning fluid injection based on boost levels, ensuring precise delivery, lower intake air temperatures, suppressed engine detonation, and optimized overall power.

The unit features large, turn-resistant adjustment dials for setting start and full-activation points, an integrated status LED, and a splash-resistant housing. The included color-coded wiring harness with a positive-lock connector makes installation straightforward while shielding against electrical shorts.

Best Uses

1. High-Boost Turbocharged & Supercharged Engines: Fine-tuning water/methanol delivery on high-boost gasoline setups running up to 40 PSI.
2. Performance Diesel Applications: Lowering Exhaust Gas Temperatures (EGTs) and augmenting power under heavy towing or racing loads.
3. System Replacement or Upgrade: Upgrading older or non-progressive controllers in existing water/methanol injection systems.
4. Detonation Suppression: Running aggressive timing and boost levels reliably on lower-octane pump gas without knock.

Features

1. Internal 40 PSI MAP Sensor: Built-in sensor reads manifold pressure up to 40 PSI directly via an integrated hose barb fitting.
2. Progressive Injection Control: Features dual turn-resistant dials to set precise start and full-flow boost thresholds.
3. Integrated Status LED & Failsafe Capability: Provides live feedback on system status, low fluid levels, or error codes.
4. Positive-Lock Wiring Harness: Color-coded, pre-terminated wiring harness with integrated fuse protection prevents accidental short-circuiting.
5. Weather-Resistant Housing: Heavy-duty enclosure equipped with molded mounting tabs and covered controls for under-hood durability.

Benefits

1. Reduces Intake Temperatures & Knock: Atomized water/methanol mist significantly cools the intake charge to prevent destructive engine detonation.
2. Unlocks Additional Horsepower: Enables safer increases in boost pressure and ignition timing without requiring expensive race fuel.
3. Efficient Fluid Delivery: Progressive metering ensures fluid is injected only as boost increases, reducing overall fluid consumption.
4. Simplified Engine Bay Wiring: The pre-wired harness integrates power, ground, and sensor lines in a single bundle for a clean installation.
5. Eliminates External Sensor Costs: Internal MAP sensor removes the need to buy and mount separate 0–5V pressure transducers or external modules.
